+Please send Emacs bug reports to bug-gnu-emacs@gnu.org.
+If possible, use M-x report-emacs-bug.
+
+This file is about changes in Emacs version 22.
+
+See files NEWS.21, NEWS.20, NEWS.19, NEWS.18, and NEWS.1-17 for changes
+in older Emacs versions.
+
+You can narrow news to a specific version by calling `view-emacs-news'
+with a prefix argument or by typing C-u C-h C-n.
+\f
+* About external Lisp packages
+
+When you upgrade to Emacs 22 from a previous version, some older
+versions of external Lisp packages are known to behave badly.
+So in general, it is recommended that you upgrade to the latest
+versions of any external Lisp packages that you are using.
+
+You should also be aware that many Lisp packages have been included
+with Emacs 22 (see the extensive list below), and you should remove
+any older versions of these packages to ensure that the Emacs 22
+version is used. You can use M-x list-load-path-shadows to find such
+older packages.
+
+Some specific packages that are known to cause problems are:
+
+** Semantic (used by CEDET, ECB, JDEE): upgrade to latest version.
+
+** cua.el, cua-mode.el: remove old versions.
+\f
+* Installation Changes in Emacs 22.2
+
+** Emacs is now licensed under the GNU GPL version 3 (or later).
+
+* Changes in Emacs 22.2
+
+** The values of `dired-recursive-deletes' and `dired-recursive-copies'
+have been changed to `top'. This means that the user is asked once,
+before deleting/copying the indicated directory recursively.
+
+** In Image mode, whenever the displayed image is wider and/or higher
+than the window, the usual keys for moving the cursor cause the image
+to be scrolled horizontally or vertically instead.
+
+** Scrollbars follow the system theme on Windows XP and later.
+Windows XP introduced themed scrollbars, but applications have to take
+special steps to use them. Emacs now has the appropriate resources linked
+in to make it use the scrollbars from the system theme.
+
+* New Modes and Packages in Emacs 22.2
+
++** bibtex-style-mode helps you write BibTeX's *.bst files.
++
+** The new package css-mode.el provides a major mode for editing CSS files.
+
+** The new package vera-mode.el provides a major mode for editing Vera files.
+
+** The new package socks.el implements the SOCKS v5 protocol.
+
+** VC
+
+*** VC backends can provide completion of revision names.
+
+*** VC has some support for Mercurial (hg).
+
++*** VC has some support for Bazaar (Bzr).
++
+*** VC has some support for Git.
+
+* Lisp Changes in Emacs 22.2.
+
+** New function `window-full-width-p' returns t if a window is as wide
+as its frame.
+
+** The new function `image-refresh' refreshes all images associated
+with a given image specification.
+
++** The new function `split-string-and-unquote' does (what?)
++
++** The new function `combine-and-quote-strings' does (what?)
+\f
+* Installation Changes in Emacs 22.1
+
+** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk'
+when you run configure. This requires Gtk+ 2.4 or newer. This port
+provides a way to display multilingual text in menus (with some caveats).
+
+** The Emacs Lisp Reference Manual is now part of the distribution.
+
+The Emacs Lisp Reference Manual in Info format is built as part of the
+Emacs build procedure and installed together with the Emacs User
+Manual. A menu item was added to the menu bar to make it easily
+accessible (Help->More Manuals->Emacs Lisp Reference).
+
+** The Introduction to Programming in Emacs Lisp manual is now part of
+the distribution.
+
+This manual is now part of the standard distribution and is installed,
+together with the Emacs User Manual, into the Info directory. A menu
+item was added to the menu bar to make it easily accessible
+(Help->More Manuals->Introduction to Emacs Lisp).
+
+** Leim is now part of the Emacs distribution.
+You no longer need to download a separate tarball in order to build
+Emacs with Leim.
+
+** Support for MacOS X was added.
+See the files mac/README and mac/INSTALL for build instructions.
+
+** Mac OS 9 port now uses the Carbon API by default. You can also
+create a non-Carbon build by specifying `NonCarbon' as a target. See
+the files mac/README and mac/INSTALL for build instructions.
+
+** Support for a Cygwin build of Emacs was added.
+
+** Support for GNU/Linux systems on X86-64 machines was added.
+
+** Support for GNU/Linux systems on S390 machines was added.
+
+** Support for GNU/Linux systems on Tensilica Xtensa machines was added.
+
+** Support for FreeBSD/Alpha has been added.
+
+** New translations of the Emacs Tutorial are available in the
+following languages: Brasilian Portuguese, Bulgarian, Chinese (both
+with simplified and traditional characters), French, Russian, and
+Italian. Type `C-u C-h t' to choose one of them in case your language
+setup doesn't automatically select the right one.
+
+** New translations of the Emacs reference card are available in the
+Brasilian Portuguese and Russian. The corresponding PostScript files
+are also included.
+
+** A French translation of the `Emacs Survival Guide' is available.
+
+** Emacs now supports new configure options `--program-prefix',
+`--program-suffix' and `--program-transform-name' that affect the names of
+installed programs.
+
+** By default, Emacs now uses a setgid helper program to update game
+scores. The directory ${localstatedir}/games/emacs is the normal
+place for game scores to be stored. You can control this with the
+configure option `--with-game-dir'. The specific user that Emacs uses
+to own the game scores is controlled by `--with-game-user'. If access
+to a game user is not available, then scores will be stored separately
+in each user's home directory.
+
+** Emacs now includes support for loading image libraries on demand.
+(Currently this feature is only used on MS Windows.) You can configure
+the supported image types and their associated dynamic libraries by
+setting the variable `image-library-alist'.
+
+** Emacs can now be built without sound support.
+
+** Emacs Lisp source files are compressed by default if `gzip' is available.
+
+** All images used in Emacs have been consolidated in etc/images and subdirs.
+See also the changes to `find-image', documented below.
+
+** Emacs comes with a new set of icons.
+These icons are displayed on the taskbar and/or titlebar when Emacs
+runs in a graphical environment. Source files for these icons can be
+found in etc/images/icons. (You can't change the icons displayed by
+Emacs by changing these files directly. On X, the icon is compiled
+into the Emacs executable; see gnu.h in the source tree. On MS
+Windows, see nt/icons/emacs.ico.)
+
+** The `emacsserver' program has been removed, replaced with Lisp code.
+
+** The `yow' program has been removed.
+Use the corresponding Emacs feature instead.
+
+** The Emacs terminal emulation in term.el uses a different terminfo name.
+The Emacs terminal emulation in term.el now uses "eterm-color" as its
+terminfo name, since term.el now supports color.
+
+** The script etc/emacs-buffer.gdb can be used with gdb to retrieve the
+contents of buffers from a core dump and save them to files easily, should
+Emacs crash.
+
+** Building with -DENABLE_CHECKING does not automatically build with union
+types any more. Add -DUSE_LISP_UNION_TYPE if you want union types.
+
+** When pure storage overflows while dumping, Emacs now prints how
+much pure storage it will approximately need.
+
+\f
+* Startup Changes in Emacs 22.1
+
+** Init file changes
+If the init file ~/.emacs does not exist, Emacs will try
+~/.emacs.d/init.el or ~/.emacs.d/init.elc. Likewise, if the shell init file
+~/.emacs_SHELL is not found, Emacs will try ~/.emacs.d/init_SHELL.sh.
+
+** Emacs can now be invoked in full-screen mode on a windowed display.
+When Emacs is invoked on a window system, the new command-line options
+`--fullwidth', `--fullheight', and `--fullscreen' produce a frame
+whose width, height, or both width and height take up the entire
+screen size. (For now, this does not work with some window managers.)
+
+** Emacs now displays a splash screen by default even if command-line
+arguments were given. The new command-line option --no-splash
+disables the splash screen; see also the variable
+`inhibit-splash-screen' (which is also aliased as
+`inhibit-startup-message').
+
+** New user option `inhibit-startup-buffer-menu'.
+When loading many files, for instance with `emacs *', Emacs normally
+displays a buffer menu. This option turns the buffer menu off.
+
+** New command line option -nbc or --no-blinking-cursor disables
+the blinking cursor on graphical terminals.
+
+** The option --script FILE runs Emacs in batch mode and loads FILE.
+It is useful for writing Emacs Lisp shell script files, because they
+can start with this line:
+
+ #!/usr/bin/emacs --script
+
+** The -f option, used from the command line to call a function,
+now reads arguments for the function interactively if it is
+an interactively callable function.
+
+** The option --directory DIR now modifies `load-path' immediately.
+Directories are added to the front of `load-path' in the order they
+appear on the command line. For example, with this command line:
+
+ emacs -batch -L .. -L /tmp --eval "(require 'foo)"
+
+Emacs looks for library `foo' in the parent directory, then in /tmp, then
+in the other directories in `load-path'. (-L is short for --directory.)
+
+** When you specify a frame size with --geometry, the size applies to
+all frames you create. A position specified with --geometry only
+affects the initial frame.
+
+** Emacs built for MS-Windows now behaves like Emacs on X does,
+with respect to its frame position: if you don't specify a position
+(in your .emacs init file, in the Registry, or with the --geometry
+command-line option), Emacs leaves the frame position to the Windows'
+window manager.
+
+** The command line option --no-windows has been changed to
+--no-window-system. The old one still works, but is deprecated.
+
+** If the environment variable DISPLAY specifies an unreachable X display,
+Emacs will now startup as if invoked with the --no-window-system option.
+
+** Emacs now reads the standard abbrevs file ~/.abbrev_defs
+automatically at startup, if it exists. When Emacs offers to save
+modified buffers, it saves the abbrevs too if they have changed. It
+can do this either silently or asking for confirmation first,
+according to the value of `save-abbrevs'.
+
+** New command line option -Q or --quick.
+This is like using -q --no-site-file, but in addition it also disables
+the fancy startup screen.
+
+** New command line option -D or --basic-display.
+Disables the menu-bar, the tool-bar, the scroll-bars, tool tips, and
+the blinking cursor.
+
+** The default is now to use a bitmap as the icon.
+The command-line options --icon-type, -i have been replaced with
+options --no-bitmap-icon, -nbi to turn the bitmap icon off.
+
+** If the environment variable EMAIL is defined, Emacs now uses its value
+to compute the default value of `user-mail-address', in preference to
+concatenation of `user-login-name' with the name of your host machine.
+
+\f
+* Incompatible Editing Changes in Emacs 22.1
+
+** You can now follow links by clicking Mouse-1 on the link.
+
+See below for more details.
+
+** When the undo information of the current command gets really large
+(beyond the value of `undo-outer-limit'), Emacs discards it and warns
+you about it.
+
+** When Emacs prompts for file names, SPC no longer completes the file name.
+This is so filenames with embedded spaces could be input without the
+need to quote the space with a C-q. The underlying changes in the
+keymaps that are active in the minibuffer are described below under
+"New keymaps for typing file names".
+
+If you want the old behavior back, put these two key bindings to your
+~/.emacs init file:
+
+ (define-key minibuffer-local-filename-completion-map
+ " " 'minibuffer-complete-word)
+ (define-key minibuffer-local-must-match-filename-map
+ " " 'minibuffer-complete-word)
+
+** The completion commands TAB, SPC and ? in the minibuffer apply only
+to the text before point. If there is text in the buffer after point,
+it remains unchanged.
+
+** In incremental search, C-w is changed. M-%, C-M-w and C-M-y are special.
+
+See below under "incremental search changes".
+
+** M-g is now a prefix key.
+M-g g and M-g M-g run goto-line.
+M-g n and M-g M-n run next-error (like C-x `).
+M-g p and M-g M-p run previous-error.
+
+** C-u M-g M-g switches to the most recent previous buffer,
+and goes to the specified line in that buffer.
+
+When goto-line starts to execute, if there's a number in the buffer at
+point then it acts as the default argument for the minibuffer.
+
+** M-o now is the prefix key for setting text properties;
+M-o M-o requests refontification.
+
+** C-x C-f RET (find-file), typing nothing in the minibuffer, is no longer
+a special case.
+
+Since the default input is the current directory, this has the effect
+of specifying the current directory. Normally that means to visit the
+directory with Dired.
+
+You can get the old behavior by typing C-x C-f M-n RET, which fetches
+the actual file name into the minibuffer.
+
+** In Dired's ! command (dired-do-shell-command), `*' and `?' now
+control substitution of the file names only when they are surrounded
+by whitespace. This means you can now use them as shell wildcards
+too. If you want to use just plain `*' as a wildcard, type `*""'; the
+doublequotes make no difference in the shell, but they prevent
+special treatment in `dired-do-shell-command'.
+
+** The info-search bindings on C-h C-f, C-h C-k and C-h C-i
+have been moved to C-h F, C-h K and C-h S.
+
+** `apply-macro-to-region-lines' now operates on all lines that begin
+in the region, rather than on all complete lines in the region.
+
+** line-move-ignore-invisible now defaults to t.
+
+** Adaptive filling misfeature removed.
+It no longer treats `NNN.' or `(NNN)' as a prefix.
+
+** The old bindings C-M-delete and C-M-backspace have been deleted,
+since there are situations where one or the other will shut down
+the operating system or your X server.
+
+** The register compatibility key bindings (deprecated since Emacs 19)
+have been removed:
+ C-x / point-to-register (Use: C-x r SPC)
+ C-x j jump-to-register (Use: C-x r j)
+ C-x x copy-to-register (Use: C-x r s)
+ C-x g insert-register (Use: C-x r i)
+
+\f
+* Editing Changes in Emacs 22.1
+
+** The max size of buffers and integers has been doubled.
+On 32bit machines, it is now 256M (i.e. 268435455).
+
+** !MEM FULL! at the start of the mode line indicates that Emacs
+cannot get any more memory for Lisp data. This often means it could
+crash soon if you do things that use more memory. On most systems,
+killing buffers will get out of this state. If killing buffers does
+not make !MEM FULL! disappear, you should save your work and start
+a new Emacs.
+
+** `undo-only' does an undo which does not redo any previous undo.
+
+** Yanking text now discards certain text properties that can
+be inconvenient when you did not expect them. The variable
+`yank-excluded-properties' specifies which ones. Insertion
+of register contents and rectangles also discards these properties.
+
+** New command `kill-whole-line' kills an entire line at once.
+By default, it is bound to C-S-<backspace>.
+
+** M-SPC (just-one-space) when given a numeric argument N
+converts whitespace around point to N spaces.
+
+** You can now switch buffers in a cyclic order with C-x C-left
+(previous-buffer) and C-x C-right (next-buffer). C-x left and
+C-x right can be used as well. The functions keep a different buffer
+cycle for each frame, using the frame-local buffer list.
+
+** C-x 5 C-o displays a specified buffer in another frame
+but does not switch to that frame. It's the multi-frame
+analogue of C-x 4 C-o.
+
+** `special-display-buffer-names' and `special-display-regexps' now
+understand two new boolean pseudo-frame-parameters `same-frame' and
+`same-window'.
+
+** New commands to operate on pairs of open and close characters:
+`insert-pair', `delete-pair', `raise-sexp'.
+
+** M-x setenv now expands environment variable references.
+
+Substrings of the form `$foo' and `${foo}' in the specified new value
+now refer to the value of environment variable foo. To include a `$'
+in the value, use `$$'.
+
+** The default values of paragraph-start and indent-line-function have
+been changed to reflect those used in Text mode rather than those used
+in Paragraph-Indent Text mode.
+
+** The default for the paper size (variable ps-paper-type) is taken
+from the locale.
+
+** Help command changes:
+
+*** Changes in C-h bindings:
+
+C-h e displays the *Messages* buffer.
+
+C-h d runs apropos-documentation.
+
+C-h r visits the Emacs Manual in Info.
+
+C-h followed by a control character is used for displaying files
+ that do not change:
+
+C-h C-f displays the FAQ.
+C-h C-e displays the PROBLEMS file.
+
+The info-search bindings on C-h C-f, C-h C-k and C-h C-i
+have been moved to C-h F, C-h K and C-h S.
+
+C-h c, C-h k, C-h w, and C-h f now handle remapped interactive commands.
+- C-h c and C-h k report the actual command (after possible remapping)
+ run by the key sequence.
+- C-h w and C-h f on a command which has been remapped now report the
+ command it is remapped to, and the keys which can be used to run
+ that command.
+
+For example, if C-k is bound to kill-line, and kill-line is remapped
+to new-kill-line, these commands now report:
+- C-h c and C-h k C-k reports:
+ C-k runs the command new-kill-line
+- C-h w and C-h f kill-line reports:
+ kill-line is remapped to new-kill-line which is on C-k, <deleteline>
+- C-h w and C-h f new-kill-line reports:
+ new-kill-line is on C-k
+
+*** The apropos commands now accept a list of words to match.
+When more than one word is specified, at least two of those words must
+be present for an item to match. Regular expression matching is still
+available.
+
+*** The new option `apropos-sort-by-scores' causes the matching items
+to be sorted according to their score. The score for an item is a
+number calculated to indicate how well the item matches the words or
+regular expression that you entered to the apropos command. The best
+match is listed first, and the calculated score is shown for each
+matching item.
+
+*** Help commands `describe-function' and `describe-key' now show function
+arguments in lowercase italics on displays that support it. To change the
+default, customize face `help-argument-name' or redefine the function
+`help-default-arg-highlight'.
+
+*** C-h v and C-h f commands now include a hyperlink to the C source for
+variables and functions defined in C (if the C source is available).
+
+*** Help mode now only makes hyperlinks for faces when the face name is
+preceded or followed by the word `face'. It no longer makes
+hyperlinks for variables without variable documentation, unless
+preceded by one of the words `variable' or `option'. It now makes
+hyperlinks to Info anchors (or nodes) if the anchor (or node) name is
+enclosed in single quotes and preceded by `info anchor' or `Info
+anchor' (in addition to earlier `info node' and `Info node'). In
+addition, it now makes hyperlinks to URLs as well if the URL is
+enclosed in single quotes and preceded by `URL'.
+
+*** The new command `describe-char' (C-u C-x =) pops up a buffer with
+description various information about a character, including its
+encodings and syntax, its text properties, how to input, overlays, and
+widgets at point. You can get more information about some of them, by
+clicking on mouse-sensitive areas or moving there and pressing RET.
+
+*** The command `list-text-properties-at' has been deleted because
+C-u C-x = gives the same information and more.
+
+*** New command `display-local-help' displays any local help at point
+in the echo area. It is bound to `C-h .'. It normally displays the
+same string that would be displayed on mouse-over using the
+`help-echo' property, but, in certain cases, it can display a more
+keyboard oriented alternative.
+
+*** New user option `help-at-pt-display-when-idle' allows you to
+automatically show the help provided by `display-local-help' on
+point-over, after suitable idle time. The amount of idle time is
+determined by the user option `help-at-pt-timer-delay' and defaults
+to one second. This feature is turned off by default.
+
+** Mark command changes:
+
+*** A prefix argument is no longer required to repeat a jump to a
+previous mark if you set `set-mark-command-repeat-pop' to t. I.e. C-u
+C-SPC C-SPC C-SPC ... cycles through the mark ring. Use C-u C-u C-SPC
+to set the mark immediately after a jump.
+
+*** Marking commands extend the region when invoked multiple times.
+
+If you type C-M-SPC (mark-sexp), M-@ (mark-word), M-h
+(mark-paragraph), or C-M-h (mark-defun) repeatedly, the marked region
+extends each time, so you can mark the next two sexps with M-C-SPC
+M-C-SPC, for example. This feature also works for
+mark-end-of-sentence, if you bind that to a key. It also extends the
+region when the mark is active in Transient Mark mode, regardless of
+the last command. To start a new region with one of marking commands
+in Transient Mark mode, you can deactivate the active region with C-g,
+or set the new mark with C-SPC.
+
+*** Some commands do something special in Transient Mark mode when the
+mark is active--for instance, they limit their operation to the
+region. Even if you don't normally use Transient Mark mode, you might
+want to get this behavior from a particular command. There are two
+ways you can enable Transient Mark mode and activate the mark, for one
+command only.
+
+One method is to type C-SPC C-SPC; this enables Transient Mark mode
+and sets the mark at point. The other method is to type C-u C-x C-x.
+This enables Transient Mark mode temporarily but does not alter the
+mark or the region.
+
+After these commands, Transient Mark mode remains enabled until you
+deactivate the mark. That typically happens when you type a command
+that alters the buffer, but you can also deactivate the mark by typing
+C-g.
+
+*** Movement commands `beginning-of-buffer', `end-of-buffer',
+`beginning-of-defun', `end-of-defun' do not set the mark if the mark
+is already active in Transient Mark mode.
+
+*** M-h (mark-paragraph) now accepts a prefix arg.
+
+With positive arg, M-h marks the current and the following paragraphs;
+if the arg is negative, it marks the current and the preceding
+paragraphs.
+
+** Incremental Search changes:
+
+*** M-% typed in isearch mode invokes `query-replace' or
+`query-replace-regexp' (depending on search mode) with the current
+search string used as the string to replace.
+
+*** C-w in incremental search now grabs either a character or a word,
+making the decision in a heuristic way. This new job is done by the
+command `isearch-yank-word-or-char'. To restore the old behavior,
+bind C-w to `isearch-yank-word' in `isearch-mode-map'.
+
+*** C-y in incremental search now grabs the next line if point is already
+at the end of a line.
+
+*** C-M-w deletes and C-M-y grabs a character in isearch mode.
+Another method to grab a character is to enter the minibuffer by `M-e'
+and to type `C-f' at the end of the search string in the minibuffer.
+
+*** Vertical scrolling is now possible within incremental search.
+To enable this feature, customize the new user option
+`isearch-allow-scroll'. User written commands which satisfy stringent
+constraints can be marked as "scrolling commands". See the Emacs manual
+for details.
+
+*** Isearch no longer adds `isearch-resume' commands to the command
+history by default. To enable this feature, customize the new
+user option `isearch-resume-in-command-history'.
+
+** Replace command changes:
+
+*** When used interactively, the commands `query-replace-regexp' and
+`replace-regexp' allow \,expr to be used in a replacement string,
+where expr is an arbitrary Lisp expression evaluated at replacement
+time. `\#' in a replacement string now refers to the count of
+replacements already made by the replacement command. All regular
+expression replacement commands now allow `\?' in the replacement
+string to specify a position where the replacement string can be
+edited for each replacement. `query-replace-regexp-eval' is now
+deprecated since it offers no additional functionality.
+
+*** query-replace uses isearch lazy highlighting when the new user option
+`query-replace-lazy-highlight' is non-nil.
+
+*** The current match in query-replace is highlighted in new face
+`query-replace' which by default inherits from isearch face.
+
+*** New user option `query-replace-skip-read-only': when non-nil,
+`query-replace' and related functions simply ignore
+a match if part of it has a read-only property.
+
+** Local variables lists:
+
+*** If the local variables list contains any variable-value pairs that
+are not known to be safe, Emacs shows a prompt asking whether to apply
+the local variables list as a whole. In earlier versions, a prompt
+was only issued for variables explicitly marked as risky (for the
+definition of risky variables, see `risky-local-variable-p').
+
+At the prompt, you can choose to save the contents of this local
+variables list to `safe-local-variable-values'. This new customizable
+option is a list of variable-value pairs that are known to be safe.
+Variables can also be marked as safe with the existing
+`safe-local-variable' property (see `safe-local-variable-p').
+However, risky variables will not be added to
+`safe-local-variable-values' in this way.
+
+*** The variable `enable-local-variables' controls how local variable
+lists are handled. t, the default, specifies the standard querying
+behavior. :safe means use only safe values, and ignore the rest.
+:all means set all variables, whether or not they are safe.
+nil means ignore them all. Anything else means always query.
+
+*** The variable `safe-local-eval-forms' specifies a list of forms that
+are ok to evaluate when they appear in an `eval' local variables
+specification. Normally Emacs asks for confirmation before evaluating
+such a form, but if the form appears in this list, no confirmation is
+needed.
+
+*** If a function has a non-nil `safe-local-eval-function' property,
+that means it is ok to evaluate some calls to that function when it
+appears in an `eval' local variables specification. If the property
+is t, then any form calling that function with constant arguments is
+ok. If the property is a function or list of functions, they are called
+with the form as argument, and if any returns t, the form is ok to call.
+
+If the form is not "ok to call", that means Emacs asks for
+confirmation as before.
+
+*** In processing a local variables list, Emacs strips the prefix and
+suffix from every line before processing all the lines.
+
+*** Text properties in local variables.
+
+A file local variables list cannot specify a string with text
+properties--any specified text properties are discarded.
+
+** File operation changes:
+
+*** Unquoted `$' in file names do not signal an error any more when
+the corresponding environment variable does not exist.
+Instead, the `$ENVVAR' text is left as is, so that `$$' quoting
+is only rarely needed.
+
+*** C-x C-f RET, typing nothing in the minibuffer, is no longer a special case.
+
+Since the default input is the current directory, this has the effect
+of specifying the current directory. Normally that means to visit the
+directory with Dired.
+
+*** C-x s (save-some-buffers) now offers an option `d' to diff a buffer
+against its file, so you can see what changes you would be saving.
+
+*** Auto Compression mode is now enabled by default.
+
+*** If the user visits a file larger than `large-file-warning-threshold',
+Emacs asks for confirmation.
+
+*** The commands copy-file, rename-file, make-symbolic-link and
+add-name-to-file, when given a directory as the "new name" argument,
+convert it to a file name by merging in the within-directory part of
+the existing file's name. (This is the same convention that shell
+commands cp, mv, and ln follow.) Thus, M-x copy-file RET ~/foo RET
+/tmp RET copies ~/foo to /tmp/foo.
+
+*** require-final-newline now has two new possible values:
+
+`visit' means add a newline (as an undoable change) if it's needed
+when visiting the file.
+
+`visit-save' means add a newline (as an undoable change) if it's
+needed when visiting the file, and also add a newline if it's needed
+when saving the file.
+
+*** The new option mode-require-final-newline controls how certain
+major modes enable require-final-newline. Any major mode that's
+designed for a kind of file that should normally end in a newline
+sets require-final-newline based on mode-require-final-newline.
+So you can customize mode-require-final-newline to control what these
+modes do.
+
+*** When you are root, and you visit a file whose modes specify
+read-only, the Emacs buffer is now read-only too. Type C-x C-q if you
+want to make the buffer writable. (As root, you can in fact alter the
+file.)
+
+*** find-file-read-only visits multiple files in read-only mode,
+when the file name contains wildcard characters.
+
+*** find-alternate-file replaces the current file with multiple files,
+when the file name contains wildcard characters. It now asks if you
+wish save your changes and not just offer to kill the buffer.
+
+*** When used interactively, `format-write-file' now asks for confirmation
+before overwriting an existing file, unless a prefix argument is
+supplied. This behavior is analogous to `write-file'.
+
+*** The variable `auto-save-file-name-transforms' now has a third element that
+controls whether or not the function `make-auto-save-file-name' will
+attempt to construct a unique auto-save name (e.g. for remote files).
+
+*** The new option `write-region-inhibit-fsync' disables calls to fsync
+in `write-region'. This can be useful on laptops to avoid spinning up
+the hard drive upon each file save. Enabling this variable may result
+in data loss, use with care.
+
+** Minibuffer changes:
+
+*** The completion commands TAB, SPC and ? in the minibuffer apply only
+to the text before point. If there is text in the buffer after point,
+it remains unchanged.
+
+*** The new file-name-shadow-mode is turned ON by default, so that when
+entering a file name, any prefix which Emacs will ignore is dimmed.
+
+*** There's a new face `minibuffer-prompt'.
+Emacs adds this face to the list of text properties stored in the
+variable `minibuffer-prompt-properties', which is used to display the
+prompt string.
+
+*** Enhanced visual feedback in `*Completions*' buffer.
+
+Completions lists use faces to highlight what all completions
+have in common and where they begin to differ.
+
+The common prefix shared by all possible completions uses the face
+`completions-common-part', while the first character that isn't the
+same uses the face `completions-first-difference'. By default,
+`completions-common-part' inherits from `default', and
+`completions-first-difference' inherits from `bold'. The idea of
+`completions-common-part' is that you can use it to make the common
+parts less visible than normal, so that the rest of the differing
+parts is, by contrast, slightly highlighted.
+
+Above fontification is always done when listing completions is
+triggered at minibuffer. If you want to fontify completions whose
+listing is triggered at the other normal buffer, you have to pass
+the common prefix of completions to `display-completion-list' as
+its second argument.
+
+*** File-name completion can now ignore specified directories.
+If an element of the list in `completion-ignored-extensions' ends in a
+slash `/', it indicates a subdirectory that should be ignored when
+completing file names. Elements of `completion-ignored-extensions'
+which do not end in a slash are never considered when a completion
+candidate is a directory.
+
+*** New user option `history-delete-duplicates'.
+If set to t when adding a new history element, all previous identical
+elements are deleted from the history list.
+
+** Redisplay changes:
+
+*** The new face `mode-line-inactive' is used to display the mode line
+of non-selected windows. The `mode-line' face is now used to display
+the mode line of the currently selected window.
+
+The new variable `mode-line-in-non-selected-windows' controls whether
+the `mode-line-inactive' face is used.
+
+*** The mode line position information now comes before the major mode.
+When the file is maintained under version control, that information
+appears between the position information and the major mode.
+
+*** You can now customize the use of window fringes. To control this
+for all frames, use M-x fringe-mode or the Show/Hide submenu of the
+top-level Options menu, or customize the `fringe-mode' variable. To
+control this for a specific frame, use the command M-x
+set-fringe-style.
+
+*** Angle icons in the fringes can indicate the buffer boundaries. In
+addition, up and down arrow bitmaps in the fringe indicate which ways
+the window can be scrolled.
+
+This behavior is activated by setting the buffer-local variable
+`indicate-buffer-boundaries' to a non-nil value. The default value of
+this variable is found in `default-indicate-buffer-boundaries'.
+
+If value is `left' or `right', both angle and arrow bitmaps are
+displayed in the left or right fringe, resp.
+
+The value can also be an alist which specifies the presence and
+position of each bitmap individually.
+
+For example, ((top . left) (t . right)) places the top angle bitmap
+in left fringe, the bottom angle bitmap in right fringe, and both
+arrow bitmaps in right fringe. To show just the angle bitmaps in the
+left fringe, but no arrow bitmaps, use ((top . left) (bottom . left)).
+
+*** On window systems, lines which are exactly as wide as the window
+(not counting the final newline character) are no longer broken into
+two lines on the display (with just the newline on the second line).
+Instead, the newline now "overflows" into the right fringe, and the
+cursor will be displayed in the fringe when positioned on that newline.
+
+The new user option 'overflow-newline-into-fringe' can be set to nil to
+revert to the old behavior of continuing such lines.
+
+*** A window can now have individual fringe and scroll-bar settings,
+in addition to the individual display margin settings.
+
+Such individual settings are now preserved when windows are split
+horizontally or vertically, a saved window configuration is restored,
+or when the frame is resized.
+
+*** When a window has display margin areas, the fringes are now
+displayed between the margins and the buffer's text area, rather than
+outside those margins.
+
+*** New face `escape-glyph' highlights control characters and escape glyphs.
+
+*** Non-breaking space and hyphens are now displayed with a special
+face, either nobreak-space or escape-glyph. You can turn this off or
+specify a different mode by setting the variable `nobreak-char-display'.
+
+*** The parameters of automatic hscrolling can now be customized.
+The variable `hscroll-margin' determines how many columns away from
+the window edge point is allowed to get before automatic hscrolling
+will horizontally scroll the window. The default value is 5.
+
+The variable `hscroll-step' determines how many columns automatic
+hscrolling scrolls the window when point gets too close to the
+window edge. If its value is zero, the default, Emacs scrolls the
+window so as to center point. If its value is an integer, it says how
+many columns to scroll. If the value is a floating-point number, it
+gives the fraction of the window's width to scroll the window.
+
+The variable `automatic-hscrolling' was renamed to
+`auto-hscroll-mode'. The old name is still available as an alias.
+
+*** Moving or scrolling through images (and other lines) taller than
+the window now works sensibly, by automatically adjusting the window's
+vscroll property.
+
+*** Preemptive redisplay now adapts to current load and bandwidth.
+
+To avoid preempting redisplay on fast computers, networks, and displays,
+the arrival of new input is now performed at regular intervals during
+redisplay. The new variable `redisplay-preemption-period' specifies
+the period; the default is to check for input every 0.1 seconds.
+
+*** The %c and %l constructs are now ignored in frame-title-format.
+Due to technical limitations in how Emacs interacts with windowing
+systems, these constructs often failed to render properly, and could
+even cause Emacs to crash.
+
+*** If value of `auto-resize-tool-bars' is `grow-only', the tool bar
+will expand as needed, but not contract automatically. To contract
+the tool bar, you must type C-l.
+
+*** New customize option `overline-margin' controls the space between
+overline and text.
+
+*** New variable `x-underline-at-descent-line' controls the relative
+position of the underline. When set, it overrides the
+`x-use-underline-position-properties' variables.
+
+** New faces:
+
+*** `mode-line-highlight' is the standard face indicating mouse sensitive
+elements on mode-line (and header-line) like `highlight' face on text
+areas.
+
+*** `mode-line-buffer-id' is the standard face for buffer identification
+parts of the mode line.
+
+*** `shadow' face defines the appearance of the "shadowed" text, i.e.
+the text which should be less noticeable than the surrounding text.
+This can be achieved by using shades of grey in contrast with either
+black or white default foreground color. This generic shadow face
+allows customization of the appearance of shadowed text in one place,
+so package-specific faces can inherit from it.
+
+*** `vertical-border' face is used for the vertical divider between windows.
+
+** Font-Lock (syntax highlighting) changes:
+
+*** All modes now support using M-x font-lock-mode to toggle
+fontification, even those such as Occur, Info, and comint-derived
+modes that do their own fontification in a special way.
+
+The variable `Info-fontify' is no longer applicable; to disable
+fontification in Info, remove `turn-on-font-lock' from
+`Info-mode-hook'.
+
+*** New standard font-lock face `font-lock-comment-delimiter-face'.
+
+*** New standard font-lock face `font-lock-preprocessor-face'.
+
+*** Easy to overlook single character negation can now be font-locked.
+You can use the new variable `font-lock-negation-char-face' and the face of
+the same name to customize this. Currently the cc-modes, sh-script-mode,
+cperl-mode and make-mode support this.
+
+*** Font-Lock mode: in major modes such as Lisp mode, where some Emacs
+features assume that an open-paren in column 0 is always outside of
+any string or comment, Font-Lock now highlights any such open-paren in
+bold-red if it is inside a string or a comment, to indicate that it
+can cause trouble. You should rewrite the string or comment so that
+the open-paren is not in column 0.
+
+*** M-o now is the prefix key for setting text properties;
+M-o M-o requests refontification.
+
+*** The default settings for JIT stealth lock parameters are changed.
+The default value for the user option jit-lock-stealth-time is now nil
+instead of 3. This setting of jit-lock-stealth-time disables stealth
+fontification: on today's machines, it may be a bug in font lock
+patterns if fontification otherwise noticeably degrades interactivity.
+If you find movement in infrequently visited buffers sluggish (and the
+major mode maintainer has no better idea), customizing
+jit-lock-stealth-time to a non-nil value will let Emacs fontify
+buffers in the background when it considers the system to be idle.
+jit-lock-stealth-nice is now 0.5 instead of 0.125 which is supposed to
+cause less load than the old defaults.
+
+*** jit-lock can now be delayed with `jit-lock-defer-time'.
+
+If this variable is non-nil, its value should be the amount of Emacs
+idle time in seconds to wait before starting fontification. For
+example, if you set `jit-lock-defer-time' to 0.25, fontification will
+only happen after 0.25s of idle time.
+
+*** contextual refontification is now separate from stealth fontification.
+
+jit-lock-defer-contextually is renamed jit-lock-contextually and
+jit-lock-context-time determines the delay after which contextual
+refontification takes place.
+
+*** lazy-lock is considered obsolete.
+
+The `lazy-lock' package is superseded by `jit-lock' and is considered
+obsolete. `jit-lock' is activated by default; if you wish to continue
+using `lazy-lock', activate it in your ~/.emacs like this:
+ (setq font-lock-support-mode 'lazy-lock-mode)
+
+If you invoke `lazy-lock-mode' directly rather than through
+`font-lock-support-mode', it now issues a warning:
+ "Use font-lock-support-mode rather than calling lazy-lock-mode"
+
+** Menu support:
+
+*** A menu item "Show/Hide" was added to the top-level menu "Options".
+This menu allows you to turn various display features on and off (such
+as the fringes, the tool bar, the speedbar, and the menu bar itself).
+You can also move the vertical scroll bar to either side here or turn
+it off completely. There is also a menu-item to toggle displaying of
+current date and time, current line and column number in the mode-line.
+
+*** Speedbar has moved from the "Tools" top level menu to "Show/Hide".
+
+*** The menu item "Open File..." has been split into two items, "New File..."
+and "Open File...". "Open File..." now opens only existing files. This is
+to support existing GUI file selection dialogs better.
+
+*** The file selection dialog for Gtk+, Mac, W32 and Motif/LessTif can be
+disabled by customizing the variable `use-file-dialog'.
+
+*** The pop up menus for Lucid now stay up if you do a fast click and can
+be navigated with the arrow keys (like Gtk+, Mac and W32).
+
+*** The menu bar for Motif/LessTif/Lucid/Gtk+ can be navigated with keys.
+Pressing F10 shows the first menu in the menu bar. Navigation is done with
+the arrow keys, select with the return key and cancel with the escape keys.
+
+*** The Lucid menus can display multilingual text in your locale. You have
+to explicitly specify a fontSet resource for this to work, for example
+`-xrm "Emacs*fontSet: -*-helvetica-medium-r-*--*-120-*-*-*-*-*-*,*"'.
+
+*** Dialogs for Lucid/Athena and LessTif/Motif now pop down on pressing
+ESC, like they do for Gtk+, Mac and W32.
+
+*** For the Gtk+ version, you can make Emacs use the old file dialog
+by setting the variable `x-gtk-use-old-file-dialog' to t. Default is to use
+the new dialog.
+
+*** You can exit dialog windows and menus by typing C-g.
+
+** Buffer Menu changes:
+
+*** The new options `buffers-menu-show-directories' and
+`buffers-menu-show-status' let you control how buffers are displayed
+in the menu dropped down when you click "Buffers" from the menu bar.
+
+`buffers-menu-show-directories' controls whether the menu displays
+leading directories as part of the file name visited by the buffer.
+If its value is `unless-uniquify', the default, directories are
+shown unless uniquify-buffer-name-style' is non-nil. The value of nil
+and t turn the display of directories off and on, respectively.
+
+`buffers-menu-show-status' controls whether the Buffers menu includes
+the modified and read-only status of the buffers. By default it is
+t, and the status is shown.
+
+Setting these variables directly does not take effect until next time
+the Buffers menu is regenerated.
+
+*** New command `Buffer-menu-toggle-files-only' toggles display of file
+buffers only in the Buffer Menu. It is bound to T in Buffer Menu
+mode.
+
+*** `buffer-menu' and `list-buffers' now list buffers whose names begin
+with a space, when those buffers are visiting files. Normally buffers
+whose names begin with space are omitted.
+
+** Mouse changes:
+
+*** You can now follow links by clicking Mouse-1 on the link.
+
+Traditionally, Emacs uses a Mouse-1 click to set point and a Mouse-2
+click to follow a link, whereas most other applications use a Mouse-1
+click for both purposes, depending on whether you click outside or
+inside a link. Now the behavior of a Mouse-1 click has been changed
+to match this context-sensitive dual behavior. (If you prefer the old
+behavior, set the user option `mouse-1-click-follows-link' to nil.)
+
+Depending on the current mode, a Mouse-2 click in Emacs can do much
+more than just follow a link, so the new Mouse-1 behavior is only
+activated for modes which explicitly mark a clickable text as a "link"
+(see the new function `mouse-on-link-p' for details). The Lisp
+packages that are included in release 22.1 have been adapted to do
+this, but external packages may not yet support this. However, there
+is no risk in using such packages, as the worst thing that could
+happen is that you get the original Mouse-1 behavior when you click
+on a link, which typically means that you set point where you click.
+
+If you want to get the original Mouse-1 action also inside a link, you
+just need to press the Mouse-1 button a little longer than a normal
+click (i.e. press and hold the Mouse-1 button for half a second before
+you release it).
+
+Dragging the Mouse-1 inside a link still performs the original
+drag-mouse-1 action, typically copy the text.
+
+You can customize the new Mouse-1 behavior via the new user options
+`mouse-1-click-follows-link' and `mouse-1-click-in-non-selected-windows'.
+
+*** If you set the new variable `mouse-autoselect-window' to a non-nil
+value, windows are automatically selected as you move the mouse from
+one Emacs window to another, even within a frame. A minibuffer window
+can be selected only when it is active.
+
+*** On X, when the window manager requires that you click on a frame to
+select it (give it focus), the selected window and cursor position
+normally changes according to the mouse click position. If you set
+the variable x-mouse-click-focus-ignore-position to t, the selected
+window and cursor position do not change when you click on a frame
+to give it focus.
+
+*** Emacs normally highlights mouse sensitive text whenever the mouse
+is over the text. By setting the new variable `mouse-highlight', you
+can optionally enable mouse highlighting only after you move the
+mouse, so that highlighting disappears when you press a key. You can
+also disable mouse highlighting.
+
+*** You can now customize if selecting a region by dragging the mouse
+shall not copy the selected text to the kill-ring by setting the new
+variable mouse-drag-copy-region to nil.
+
+*** Under X, mouse-wheel-mode is turned on by default.
+
+*** Emacs ignores mouse-2 clicks while the mouse wheel is being moved.
+
+People tend to push the mouse wheel (which counts as a mouse-2 click)
+unintentionally while turning the wheel, so these clicks are now
+ignored. You can customize this with the mouse-wheel-click-event and
+mouse-wheel-inhibit-click-time variables.
+
+*** mouse-wheels can now scroll a specific fraction of the window
+(rather than a fixed number of lines) and the scrolling is `progressive'.
+
+** Multilingual Environment (Mule) changes:
+
+*** You can disable character translation for a file using the -*-
+construct. Include `enable-character-translation: nil' inside the
+-*-...-*- to disable any character translation that may happen by
+various global and per-coding-system translation tables. You can also
+specify it in a local variable list at the end of the file. For
+shortcut, instead of using this long variable name, you can append the
+character "!" at the end of coding-system name specified in -*-
+construct or in a local variable list. For example, if a file has the
+following header, it is decoded by the coding system `iso-latin-1'
+without any character translation:
+;; -*- coding: iso-latin-1!; -*-
+
+*** Language environment and various default coding systems are setup
+more correctly according to the current locale name. If the locale
+name doesn't specify a charset, the default is what glibc defines.
+This change can result in using the different coding systems as
+default in some locale (e.g. vi_VN).
+
+*** The keyboard-coding-system is now automatically set based on your
+current locale settings if you are not using a window system. This
+can mean that the META key doesn't work but generates non-ASCII
+characters instead, depending on how the terminal (or terminal
+emulator) works. Use `set-keyboard-coding-system' (or customize
+keyboard-coding-system) if you prefer META to work (the old default)
+or if the locale doesn't describe the character set actually generated
+by the keyboard. See Info node `Unibyte Mode'.
+
+*** The new command `set-file-name-coding-system' (C-x RET F) sets
+coding system for encoding and decoding file names. A new menu item
+(Options->Mule->Set Coding Systems->For File Name) invokes this
+command.
+
+*** The new command `revert-buffer-with-coding-system' (C-x RET r)
+revisits the current file using a coding system that you specify.
+
+*** New command `recode-region' decodes the region again by a specified
+coding system.
+
+*** The new command `recode-file-name' changes the encoding of the name
+of a file.
+
+*** New command `ucs-insert' inserts a character specified by its
+unicode.
+
+*** New command quail-show-key shows what key (or key sequence) to type
+in the current input method to input a character at point.
+
+*** Limited support for character `unification' has been added.
+Emacs now knows how to translate between different representations of
+the same characters in various Emacs charsets according to standard
+Unicode mappings. This applies mainly to characters in the ISO 8859
+sets plus some other 8-bit sets, but can be extended. For instance,
+translation works amongst the Emacs ...-iso8859-... charsets and the
+mule-unicode-... ones.
+
+By default this translation happens automatically on encoding.
+Self-inserting characters are translated to make the input conformant
+with the encoding of the buffer in which it's being used, where
+possible.
+
+You can force a more complete unification with the user option
+unify-8859-on-decoding-mode. That maps all the Latin-N character sets
+into Unicode characters (from the latin-iso8859-1 and
+mule-unicode-0100-24ff charsets) on decoding. Note that this mode
+will often effectively clobber data with an iso-2022 encoding.
+
+*** New language environments (set up automatically according to the
+locale): Belarusian, Bulgarian, Chinese-EUC-TW, Croatian, Esperanto,
+French, Georgian, Italian, Latin-7, Latvian, Lithuanian, Malayalam,
+Russian, Russian, Slovenian, Swedish, Tajik, Tamil, UTF-8,Ukrainian,
+Welsh,Latin-6, Windows-1255.
+
+*** New input methods: latin-alt-postfix, latin-postfix, latin-prefix,
+belarusian, bulgarian-bds, bulgarian-phonetic, chinese-sisheng (for
+Chinese Pinyin characters), croatian, dutch, georgian, latvian-keyboard,
+lithuanian-numeric, lithuanian-keyboard, malayalam-inscript, rfc1345,
+russian-computer, sgml, slovenian, tamil-inscript, ukrainian-computer,
+ucs, vietnamese-telex, welsh.
+
+*** There is support for decoding Greek and Cyrillic characters into
+either Unicode (the mule-unicode charsets) or the iso-8859 charsets,
+when possible. The latter are more space-efficient.
+ This is controlled by user option utf-fragment-on-decoding.
+
+*** Improved Thai support. A new minor mode `thai-word-mode' (which is
+automatically activated if you select Thai as a language
+environment) changes key bindings of most word-oriented commands to
+versions which recognize Thai words. Affected commands are
+ M-f (forward-word)
+ M-b (backward-word)
+ M-d (kill-word)
+ M-DEL (backward-kill-word)
+ M-t (transpose-words)
+ M-q (fill-paragraph)
+
+*** Indian support has been updated.
+The in-is13194 coding system is now Unicode-based. CDAC fonts are
+assumed. There is a framework for supporting various Indian scripts,
+but currently only Devanagari, Malayalam and Tamil are supported.
+
+*** The utf-8/16 coding systems have been enhanced.
+By default, untranslatable utf-8 sequences are simply composed into
+single quasi-characters. User option `utf-translate-cjk-mode' (it is
+turned on by default) arranges to translate many utf-8 CJK character
+sequences into real Emacs characters in a similar way to the Mule-UCS
+system. As this loads a fairly big data on demand, people who are not
+interested in CJK characters may want to customize it to nil.
+You can augment/amend the CJK translation via hash tables
+`ucs-mule-cjk-to-unicode' and `ucs-unicode-to-mule-cjk'. The utf-8
+coding system now also encodes characters from most of Emacs's
+one-dimensional internal charsets, specifically the ISO-8859 ones.
+The utf-16 coding system is affected similarly.
+
+*** A UTF-7 coding system is available in the library `utf-7'.
+
+*** A new coding system `euc-tw' has been added for traditional Chinese
+in CNS encoding; it accepts both Big 5 and CNS as input; on saving,
+Big 5 is then converted to CNS.
+
+*** Many new coding systems are available in the `code-pages' library.
+These include complete versions of most of those in codepage.el, based
+on Unicode mappings. `codepage-setup' is now obsolete and is used
+only in the MS-DOS port of Emacs. All coding systems defined in
+`code-pages' are auto-loaded.
+
+*** New variable `utf-translate-cjk-unicode-range' controls which
+Unicode characters to translate in `utf-translate-cjk-mode'.
+
+*** iso-10646-1 (`Unicode') fonts can be used to display any range of
+characters encodable by the utf-8 coding system. Just specify the
+fontset appropriately.
+
+** Customize changes:
+
+*** Custom themes are collections of customize options. Create a
+custom theme with M-x customize-create-theme. Use M-x load-theme to
+load and enable a theme, and M-x disable-theme to disable it. Use M-x
+enable-theme to enable a disabled theme.
+
+*** The commands M-x customize-face and M-x customize-face-other-window
+now look at the character after point. If a face or faces are
+specified for that character, the commands by default customize those
+faces.
+
+*** The face-customization widget has been reworked to be less confusing.
+In particular, when you enable a face attribute using the corresponding
+check-box, there's no longer a redundant `*' option in value selection
+for that attribute; the values you can choose are only those which make
+sense for the attribute. When an attribute is de-selected by unchecking
+its check-box, then the (now ignored, but still present temporarily in
+case you re-select the attribute) value is hidden.
+
+*** When you set or reset a variable's value in a Customize buffer,
+the previous value becomes the "backup value" of the variable.
+You can go back to that backup value by selecting "Use Backup Value"
+under the "[State]" button.
+
+** Dired mode:
+
+*** In Dired's ! command (dired-do-shell-command), `*' and `?' now
+control substitution of the file names only when they are surrounded
+by whitespace. This means you can now use them as shell wildcards
+too. If you want to use just plain `*' as a wildcard, type `*""'; the
+double quotes make no difference in the shell, but they prevent
+special treatment in `dired-do-shell-command'.
+
+*** The Dired command `dired-goto-file' is now bound to j, not M-g.
+This is to avoid hiding the global key binding of M-g.
+
+*** New faces dired-header, dired-mark, dired-marked, dired-flagged,
+dired-ignored, dired-directory, dired-symlink, dired-warning
+introduced for Dired mode instead of font-lock faces.
+
+*** New Dired command `dired-compare-directories' marks files
+with different file attributes in two dired buffers.
+
+*** New Dired command `dired-do-touch' (bound to T) changes timestamps
+of marked files with the value entered in the minibuffer.
+
+*** In Dired, the w command now stores the current line's file name
+into the kill ring. With a zero prefix arg, it stores the absolute file name.
+
+*** In Dired-x, Omitting files is now a minor mode, dired-omit-mode.
+
+The mode toggling command is bound to M-o. A new command
+dired-mark-omitted, bound to * O, marks omitted files. The variable
+dired-omit-files-p is obsoleted, use the mode toggling function
+instead.
+
+*** The variables dired-free-space-program and dired-free-space-args
+have been renamed to directory-free-space-program and
+directory-free-space-args, and they now apply whenever Emacs puts a
+directory listing into a buffer.
+
+** Comint changes:
+
+*** The new INSIDE_EMACS environment variable is set to "t" in subshells
+running inside Emacs. This supersedes the EMACS environment variable,
+which will be removed in a future Emacs release. Programs that need
+to know whether they are started inside Emacs should check INSIDE_EMACS
+instead of EMACS.
+
+*** The comint prompt can now be made read-only, using the new user
+option `comint-prompt-read-only'. This is not enabled by default,
+except in IELM buffers. The read-only status of IELM prompts can be
+controlled with the new user option `ielm-prompt-read-only', which
+overrides `comint-prompt-read-only'.
+
+The new commands `comint-kill-whole-line' and `comint-kill-region'
+support editing comint buffers with read-only prompts.
+
+`comint-kill-whole-line' is like `kill-whole-line', but ignores both
+read-only and field properties. Hence, it always kill entire
+lines, including any prompts.
+
+`comint-kill-region' is like `kill-region', except that it ignores
+read-only properties, if it is safe to do so. This means that if any
+part of a prompt is deleted, then the entire prompt must be deleted
+and that all prompts must stay at the beginning of a line. If this is
+not the case, then `comint-kill-region' behaves just like
+`kill-region' if read-only properties are involved: it copies the text
+to the kill-ring, but does not delete it.
+
+*** The new command `comint-insert-previous-argument' in comint-derived
+modes (shell-mode, etc.) inserts arguments from previous command lines,
+like bash's `ESC .' binding. It is bound by default to `C-c .', but
+otherwise behaves quite similarly to the bash version.
+
+*** `comint-use-prompt-regexp-instead-of-fields' has been renamed
+`comint-use-prompt-regexp'. The old name has been kept as an alias,
+but declared obsolete.
+
+** M-x Compile changes:
+
+*** M-x compile has become more robust and reliable
+
+Quite a few more kinds of messages are recognized. Messages that are
+recognized as warnings or informational come in orange or green, instead of
+red. Informational messages are by default skipped with `next-error'
+(controlled by `compilation-skip-threshold').
+
+Location data is collected on the fly as the *compilation* buffer changes.
+This means you could modify messages to make them point to different files.
+This also means you can not go to locations of messages you may have deleted.
+
+The variable `compilation-error-regexp-alist' has now become customizable. If
+you had added your own regexps to this, you'll probably need to include a
+leading `^', otherwise they'll match anywhere on a line. There is now also a
+`compilation-mode-font-lock-keywords' and it nicely handles all the checks
+that configure outputs and -o options so you see at a glance where you are.
+
+The new file etc/compilation.txt gives examples of each type of message.
+
+*** New user option `compilation-environment'.
+This option allows you to specify environment variables for inferior
+compilation processes without affecting the environment that all
+subprocesses inherit.
+
+*** New user option `compilation-disable-input'.
+If this is non-nil, send end-of-file as compilation process input.
+
+*** New options `next-error-highlight' and `next-error-highlight-no-select'
+specify the method of highlighting of the corresponding source line
+in new face `next-error'.
+
+*** A new minor mode `next-error-follow-minor-mode' can be used in
+compilation-mode, grep-mode, occur-mode, and diff-mode (i.e. all the
+modes that can use `next-error'). In this mode, cursor motion in the
+buffer causes automatic display in another window of the corresponding
+matches, compilation errors, etc. This minor mode can be toggled with
+C-c C-f.
+
+*** When the left fringe is displayed, an arrow points to current message in
+the compilation buffer.
+
+*** The new variable `compilation-context-lines' controls lines of leading
+context before the current message. If nil and the left fringe is displayed,
+it doesn't scroll the compilation output window. If there is no left fringe,
+no arrow is displayed and a value of nil means display the message at the top
+of the window.
+
+** Occur mode changes:
+
+*** The new command `multi-occur' is just like `occur', except it can
+search multiple buffers. There is also a new command
+`multi-occur-in-matching-buffers' which allows you to specify the
+buffers to search by their filenames or buffer names. Internally,
+Occur mode has been rewritten, and now uses font-lock, among other
+changes.
+
+*** You can now use next-error (C-x `) and previous-error to advance to
+the next/previous matching line found by M-x occur.
+
+*** In the *Occur* buffer, `o' switches to it in another window, and
+C-o displays the current line's occurrence in another window without
+switching to it.
+
+** Grep changes:
+
+*** Grep has been decoupled from compilation mode setup.
+
+There's a new separate package grep.el, with its own submenu and
+customization group.
+
+*** `grep-find' is now also available under the name `find-grep' where
+people knowing `find-grep-dired' would probably expect it.
+
+*** New commands `lgrep' (local grep) and `rgrep' (recursive grep) are
+more user-friendly versions of `grep' and `grep-find', which prompt
+separately for the regular expression to match, the files to search,
+and the base directory for the search. Case sensitivity of the
+search is controlled by the current value of `case-fold-search'.
+
+These commands build the shell commands based on the new variables
+`grep-template' (lgrep) and `grep-find-template' (rgrep).
+
+The files to search can use aliases defined in `grep-files-aliases'.
+
+Subdirectories listed in `grep-find-ignored-directories' such as those
+typically used by various version control systems, like CVS and arch,
+are automatically skipped by `rgrep'.
+
+*** The grep commands provide highlighting support.
+
+Hits are fontified in green, and hits in binary files in orange. Grep buffers
+can be saved and automatically revisited.
+
+*** New option `grep-highlight-matches' highlights matches in *grep*
+buffer. It uses a special feature of some grep programs which accept
+--color option to output markers around matches. When going to the next
+match with `next-error' the exact match is highlighted in the source
+buffer. Otherwise, if `grep-highlight-matches' is nil, the whole
+source line is highlighted.
+
+*** New key bindings in grep output window:
+SPC and DEL scrolls window up and down. C-n and C-p moves to next and
+previous match in the grep window. RET jumps to the source line of
+the current match. `n' and `p' shows next and previous match in
+other window, but does not switch buffer. `{' and `}' jumps to the
+previous or next file in the grep output. TAB also jumps to the next
+file.
+
+*** M-x grep now tries to avoid appending `/dev/null' to the command line
+by using GNU grep `-H' option instead. M-x grep automatically
+detects whether this is possible or not the first time it is invoked.
+When `-H' is used, the grep command line supplied by the user is passed
+unchanged to the system to execute, which allows more complicated
+command lines to be used than was possible before.
+
+*** The new variables `grep-window-height' and `grep-scroll-output' override
+the corresponding compilation mode settings, for grep commands only.
+
+** Cursor display changes:
+
+*** Emacs can produce an underscore-like (horizontal bar) cursor.
+The underscore cursor is set by putting `(cursor-type . hbar)' in
+default-frame-alist. It supports variable heights, like the `bar'
+cursor does.
+
+*** The variable `cursor-in-non-selected-windows' can now be set to any
+of the recognized cursor types.
+
+*** Display of hollow cursors now obeys the buffer-local value (if any)
+of `cursor-in-non-selected-windows' in the buffer that the cursor
+appears in.
+
+*** On text terminals, the variable `visible-cursor' controls whether Emacs
+uses the "very visible" cursor (the default) or the normal cursor.
+
+*** The X resource cursorBlink can be used to turn off cursor blinking.
+
+*** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is
+now controlled by the variable `blink-cursor-alist'.
+
+** X Windows Support:
+
+*** Emacs now supports drag and drop for X. Dropping a file on a window
+opens it, dropping text inserts the text. Dropping a file on a dired
+buffer copies or moves the file to that directory.
+
+*** Under X11, it is possible to swap Alt and Meta (and Super and Hyper).
+The new variables `x-alt-keysym', `x-hyper-keysym', `x-meta-keysym',
+and `x-super-keysym' can be used to choose which keysyms Emacs should
+use for the modifiers. For example, the following two lines swap
+Meta and Alt:
+ (setq x-alt-keysym 'meta)
+ (setq x-meta-keysym 'alt)
+
+*** The X resource useXIM can be used to turn off use of XIM, which can
+speed up Emacs with slow networking to the X server.
+
+If the configure option `--without-xim' was used to turn off use of
+XIM by default, the X resource useXIM can be used to turn it on.
+
+*** The new variable `x-select-request-type' controls how Emacs
+requests X selection. The default value is nil, which means that
+Emacs requests X selection with types COMPOUND_TEXT and UTF8_STRING,
+and use the more appropriately result.
+
+*** The scrollbar under LessTif or Motif has a smoother drag-scrolling.
+On the other hand, the size of the thumb does not represent the actual
+amount of text shown any more (only a crude approximation of it).
+
+** Xterm support:
+
+*** If you enable Xterm Mouse mode, Emacs will respond to mouse clicks
+on the mode line, header line and display margin, when run in an xterm.
+
+*** Improved key bindings support when running in an xterm.
+When Emacs is running in an xterm more key bindings are available.
+The following should work:
+{C,S,C-S,A}-{right,left,up,down,prior,next,delete,insert,F1-12}.
+These key bindings work on xterm from X.org 6.8 (and later versions),
+they might not work on some older versions of xterm, or on some
+proprietary versions.
+The various keys generated by xterm when the "modifyOtherKeys"
+resource is set are also supported.
+
+** Character terminal color support changes:
+
+*** The new command-line option --color=MODE lets you specify a standard
+mode for a tty color support. It is meant to be used on character
+terminals whose capabilities are not set correctly in the terminal
+database, or with terminal emulators which support colors, but don't
+set the TERM environment variable to a name of a color-capable
+terminal. "emacs --color" uses the same color commands as GNU `ls'
+when invoked with "ls --color", so if your terminal can support colors
+in "ls --color", it will support "emacs --color" as well. See the
+user manual for the possible values of the MODE parameter.
+
+*** Emacs now supports several character terminals which provide more
+than 8 colors. For example, for `xterm', 16-color, 88-color, and
+256-color modes are supported. Emacs automatically notes at startup
+the extended number of colors, and defines the appropriate entries for
+all of these colors.
+
+*** Emacs now uses the full range of available colors for the default
+faces when running on a color terminal, including 16-, 88-, and
+256-color xterms. This means that when you run "emacs -nw" on an
+88-color or 256-color xterm, you will see essentially the same face
+colors as on X.
+
+*** There's a new support for colors on `rxvt' terminal emulator.
+
+** ebnf2ps changes:
+
+*** New option `ebnf-arrow-extra-width' which specify extra width for arrow
+shape drawing.
+The extra width is used to avoid that the arrowhead and the terminal border
+overlap. It depends on `ebnf-arrow-shape' and `ebnf-line-width'.
+
+*** New option `ebnf-arrow-scale' which specify the arrow scale.
+Values lower than 1.0, shrink the arrow.
+Values greater than 1.0, expand the arrow.
+\f
+* New Modes and Packages in Emacs 22.1
+
+** CUA mode is now part of the Emacs distribution.
+
+The new cua package provides CUA-like keybindings using C-x for
+cut (kill), C-c for copy, C-v for paste (yank), and C-z for undo.
+With cua, the region can be set and extended using shifted movement
+keys (like pc-selection-mode) and typed text replaces the active
+region (like delete-selection-mode). Do not enable these modes with
+cua-mode. Customize the variable `cua-mode' to enable cua.
+
+The cua-selection-mode enables the CUA keybindings for the region but
+does not change the bindings for C-z/C-x/C-c/C-v. It can be used as a
+replacement for pc-selection-mode.
+
+In addition, cua provides unified rectangle support with visible
+rectangle highlighting: Use C-return to start a rectangle, extend it
+using the movement commands (or mouse-3), and cut or copy it using C-x
+or C-c (using C-w and M-w also works).
+
+Use M-o and M-c to `open' or `close' the rectangle, use M-b or M-f, to
+fill it with blanks or another character, use M-u or M-l to upcase or
+downcase the rectangle, use M-i to increment the numbers in the
+rectangle, use M-n to fill the rectangle with a numeric sequence (such
+as 10 20 30...), use M-r to replace a regexp in the rectangle, and use
+M-' or M-/ to restrict command on the rectangle to a subset of the
+rows. See the commentary in cua-base.el for more rectangle commands.
+
+Cua also provides unified support for registers: Use a numeric
+prefix argument between 0 and 9, i.e. M-0 .. M-9, for C-x, C-c, and
+C-v to cut or copy into register 0-9, or paste from register 0-9.
+
+The last text deleted (not killed) is automatically stored in
+register 0. This includes text deleted by typing text.
+
+Finally, cua provides a global mark which is set using S-C-space.
+When the global mark is active, any text which is cut or copied is
+automatically inserted at the global mark position. See the
+commentary in cua-base.el for more global mark related commands.
+
+The features of cua also works with the standard Emacs bindings for
+kill, copy, yank, and undo. If you want to use cua mode, but don't
+want the C-x, C-c, C-v, and C-z bindings, you can customize the
+`cua-enable-cua-keys' variable.
+
+Note: This version of cua mode is not backwards compatible with older
+versions of cua.el and cua-mode.el. To ensure proper operation, you
+must remove older versions of cua.el or cua-mode.el as well as the
+loading and customization of those packages from the .emacs file.
+
+** Tramp is now part of the distribution.
+
+This package is similar to Ange-FTP: it allows you to edit remote
+files. But whereas Ange-FTP uses FTP to access the remote host,
+Tramp uses a shell connection. The shell connection is always used
+for filename completion and directory listings and suchlike, but for
+the actual file transfer, you can choose between the so-called
+`inline' methods (which transfer the files through the shell
+connection using base64 or uu encoding) and the `out-of-band' methods
+(which invoke an external copying program such as `rcp' or `scp' or
+`rsync' to do the copying).
+
+Shell connections can be acquired via `rsh', `ssh', `telnet' and also
+`su' and `sudo'. Ange-FTP is still supported via the `ftp' method.
+
+If you want to disable Tramp you should set
+
+ (setq tramp-default-method "ftp")
+
+Removing Tramp, and re-enabling Ange-FTP, can be achieved by M-x
+tramp-unload-tramp.
+
+** The image-dired.el package allows you to easily view, tag and in
+other ways manipulate image files and their thumbnails, using dired as
+the main interface. Image-Dired provides functionality to generate
+simple image galleries.
+
+** Image files are normally visited in Image mode, which lets you toggle
+between viewing the image and viewing the text using C-c C-c.
+
+** The new python.el package is used to edit Python and Jython programs.
+
+** The URL package (which had been part of W3) is now part of Emacs.
+
+** Calc is now part of the Emacs distribution.
+
+Calc is an advanced desk calculator and mathematical tool written in
+Emacs Lisp. The prefix for Calc has been changed to `C-x *' and Calc
+can be started with `C-x * *'. The Calc manual is separate from the
+Emacs manual; within Emacs, type "C-h i m calc RET" to read the
+manual. A reference card is available in `etc/calccard.tex' and
+`etc/calccard.ps'.
+
+** Org mode is now part of the Emacs distribution
+
+Org mode is a mode for keeping notes, maintaining ToDo lists, and
+doing project planning with a fast and effective plain-text system.
+It also contains a plain-text table editor with spreadsheet-like
+capabilities.
+
+The Org mode table editor can be integrated into any major mode by
+activating the minor Orgtbl-mode.
+
+The documentation for org-mode is in a separate manual; within Emacs,
+type "C-h i m org RET" to read that manual. A reference card is
+available in `etc/orgcard.tex' and `etc/orgcard.ps'.
+
+** ERC is now part of the Emacs distribution.
+
+ERC is a powerful, modular, and extensible IRC client for Emacs.
+
+To see what modules are available, type
+M-x customize-option erc-modules RET.
+
+To start an IRC session with ERC, type M-x erc, and follow the prompts
+for server, port, and nick.
+
+** Rcirc is now part of the Emacs distribution.
+
+Rcirc is an Internet relay chat (IRC) client. It supports
+simultaneous connections to multiple IRC servers. Each discussion
+takes place in its own buffer. For each connection you can join
+several channels (many-to-many) and participate in private
+(one-to-one) chats. Both channel and private chats are contained in
+separate buffers.
+
+To start an IRC session using the default parameters, type M-x irc.
+If you type C-u M-x irc, it prompts you for the server, nick, port and
+startup channel parameters before connecting.
+
+** The new package ibuffer provides a powerful, completely
+customizable replacement for buff-menu.el.
+
+** Newsticker is now part of the Emacs distribution.
+
+Newsticker asynchronously retrieves headlines (RSS) from a list of news
+sites, prepares these headlines for reading, and allows for loading the
+corresponding articles in a web browser. Its documentation is in a
+separate manual.
+
+** The wdired.el package allows you to use normal editing commands on Dired
+buffers to change filenames, permissions, etc...
+
+** Ido mode is now part of the Emacs distribution.
+
+The ido (interactively do) package is an extension of the iswitchb
+package to do interactive opening of files and directories in addition
+to interactive buffer switching. Ido is a superset of iswitchb (with
+a few exceptions), so don't enable both packages.
+
+** The new global minor mode `file-name-shadow-mode' modifies the way
+filenames being entered by the user in the minibuffer are displayed, so
+that it's clear when part of the entered filename will be ignored due to
+Emacs' filename parsing rules. The ignored portion can be made dim,
+invisible, or otherwise less visually noticeable. The display method can
+be displayed by customizing the variable `file-name-shadow-properties'.
+
+** Emacs' keyboard macro facilities have been enhanced by the new
+kmacro package.
+
+Keyboard macros are now defined and executed via the F3 and F4 keys:
+F3 starts a macro, F4 ends the macro, and pressing F4 again executes
+the last macro. While defining the macro, F3 inserts a counter value
+which automatically increments every time the macro is executed.
+
+There is now a keyboard macro ring which stores the most recently
+defined macros.
+
+The C-x C-k sequence is now a prefix for the kmacro keymap which
+defines bindings for moving through the keyboard macro ring,
+C-x C-k C-p and C-x C-k C-n, editing the last macro C-x C-k C-e,
+manipulating the macro counter and format via C-x C-k C-c,
+C-x C-k C-a, and C-x C-k C-f. See the commentary in kmacro.el
+for more commands.
+
+The original macro bindings C-x (, C-x ), and C-x e are still
+available, but they now interface to the keyboard macro ring too.
+
+The C-x e command now automatically terminates the current macro
+before calling it, if used while defining a macro.
+
+In addition, when ending or calling a macro with C-x e, the macro can
+be repeated immediately by typing just the `e'. You can customize
+this behavior via the variables kmacro-call-repeat-key and
+kmacro-call-repeat-with-arg.
+
+Keyboard macros can now be debugged and edited interactively.
+C-x C-k SPC steps through the last keyboard macro one key sequence
+at a time, prompting for the actions to take.
+
+** The new keypad setup package provides several common bindings for
+the numeric keypad which is available on most keyboards. The numeric
+keypad typically has the digits 0 to 9, a decimal point, keys marked
++, -, /, and *, an Enter key, and a NumLock toggle key. The keypad
+package only controls the use of the digit and decimal keys.
+
+By customizing the variables `keypad-setup', `keypad-shifted-setup',
+`keypad-numlock-setup', and `keypad-numlock-shifted-setup', or by
+using the function `keypad-setup', you can rebind all digit keys and
+the decimal key of the keypad in one step for each of the four
+possible combinations of the Shift key state (not pressed/pressed) and
+the NumLock toggle state (off/on).
+
+The choices for the keypad keys in each of the above states are:
+`Plain numeric keypad' where the keys generates plain digits,
+`Numeric keypad with decimal key' where the character produced by the
+decimal key can be customized individually (for internationalization),
+`Numeric Prefix Arg' where the keypad keys produce numeric prefix args
+for Emacs editing commands, `Cursor keys' and `Shifted Cursor keys'
+where the keys work like (shifted) arrow keys, home/end, etc., and
+`Unspecified/User-defined' where the keypad keys (kp-0, kp-1, etc.)
+are left unspecified and can be bound individually through the global
+or local keymaps.
+
+** The printing package is now part of the Emacs distribution.
+
+If you enable the printing package by including (require 'printing) in
+the .emacs file, the normal Print item on the File menu is replaced
+with a Print sub-menu which allows you to preview output through
+ghostview, use ghostscript to print (if you don't have a PostScript
+printer) or send directly to printer a PostScript code generated by
+`ps-print' package. Use M-x pr-help for more information.
+
+** The new package longlines.el provides a minor mode for editing text
+files composed of long lines, based on the `use-hard-newlines'
+mechanism. The long lines are broken up by inserting soft newlines,
+which are automatically removed when saving the file to disk or
+copying into the kill ring, clipboard, etc. By default, Longlines
+mode inserts soft newlines automatically during editing, a behavior
+referred to as "soft word wrap" in other text editors. This is
+similar to Refill mode, but more reliable. To turn the word wrap
+feature off, set `longlines-auto-wrap' to nil.
+
+** SES mode (ses-mode) is a new major mode for creating and editing
+spreadsheet files. Besides the usual Emacs features (intuitive command
+letters, undo, cell formulas in Lisp, plaintext files, etc.) it also offers
+viral immunity and import/export of tab-separated values.
+
+** The new package table.el implements editable, WYSIWYG, embedded
+`text tables' in Emacs buffers. It simulates the effect of putting
+these tables in a special major mode. The package emulates WYSIWYG
+table editing available in modern word processors. The package also
+can generate a table source in typesetting and markup languages such
+as latex and html from the visually laid out text table.
+
+** Filesets are collections of files. You can define a fileset in
+various ways, such as based on a directory tree or based on
+program files that include other program files.
+
+Once you have defined a fileset, you can perform various operations on
+all the files in it, such as visiting them or searching and replacing
+in them.
+
+** The minor mode Reveal mode makes text visible on the fly as you
+move your cursor into hidden regions of the buffer.
+It should work with any package that uses overlays to hide parts
+of a buffer, such as outline-minor-mode, hs-minor-mode, hide-ifdef-mode, ...
+
+There is also Global Reveal mode which affects all buffers.
+
+** New minor mode, Visible mode, toggles invisibility in the current buffer.
+When enabled, it makes all invisible text visible. When disabled, it
+restores the previous value of `buffer-invisibility-spec'.
+
+** The new package flymake.el does on-the-fly syntax checking of program
+source files. See the Flymake's Info manual for more details.
+
+** savehist saves minibuffer histories between sessions.
+To use this feature, turn on savehist-mode in your `.emacs' file.
+
+** The ruler-mode.el library provides a minor mode for displaying an
+"active" ruler in the header line. You can use the mouse to visually
+change the `fill-column', `window-margins' and `tab-stop-list'
+settings.
+
+** The file t-mouse.el is now part of Emacs and provides access to mouse
+events from the console. It still requires gpm to work but has been updated
+for Emacs 22. In particular, the mode-line is now position sensitive.
+
+** The new package scroll-lock.el provides the Scroll Lock minor mode
+for pager-like scrolling. Keys which normally move point by line or
+paragraph will scroll the buffer by the respective amount of lines
+instead and point will be kept vertically fixed relative to window
+boundaries during scrolling.
+
+** The new global minor mode `size-indication-mode' (off by default)
+shows the size of accessible part of the buffer on the mode line.
+
+** The new package conf-mode.el handles thousands of configuration files, with
+varying syntaxes for comments (;, #, //, /* */ or !), assignment (var = value,
+var : value, var value or keyword var value) and sections ([section] or
+section { }). Many files under /etc/, or with suffixes like .cf through
+.config, .properties (Java), .desktop (KDE/Gnome), .ini and many others are
+recognized.
+
+** GDB-Script-mode is used for files like .gdbinit.
+
+** The new package dns-mode.el adds syntax highlighting of DNS master files.
+It is a modern replacement for zone-mode.el, which is now obsolete.
+
+** `cfengine-mode' is a major mode for editing GNU Cfengine
+configuration files.
+
+** The TCL package tcl-mode.el was replaced by tcl.el.
+This was actually done in Emacs-21.1, and was not documented.
+\f
+* Changes in Specialized Modes and Packages in Emacs 22.1:
+
+** Changes in Dired
+
+*** Bindings for Image-Dired added.
+Several new keybindings, all starting with the C-t prefix, have been
+added to Dired. They are all bound to commands in Image-Dired. As a
+starting point, mark some image files in a dired buffer and do C-t d
+to display thumbnails of them in a separate buffer.
+
+** Info mode changes
+
+*** Images in Info pages are supported.
+
+Info pages show embedded images, in Emacs frames with image support.
+Info documentation that includes images, processed with makeinfo
+version 4.7 or newer, compiles to Info pages with embedded images.
+
+*** `Info-index' offers completion.
+
+*** http and ftp links in Info are now operational: they look like cross
+references and following them calls `browse-url'.
+
+*** isearch in Info uses Info-search and searches through multiple nodes.
+
+Before leaving the initial Info node isearch fails once with the error
+message [initial node], and with subsequent C-s/C-r continues through
+other nodes. When isearch fails for the rest of the manual, it wraps
+around the whole manual to the top/final node. The user option
+`Info-isearch-search' controls whether to use Info-search for isearch,
+or the default isearch search function that wraps around the current
+Info node.
+
+*** New search commands: `Info-search-case-sensitively' (bound to S),
+`Info-search-backward', and `Info-search-next' which repeats the last
+search without prompting for a new search string.
+
+*** New command `info-apropos' searches the indices of the known
+Info files on your system for a string, and builds a menu of the
+possible matches.
+
+*** New command `Info-history-forward' (bound to r and new toolbar icon)
+moves forward in history to the node you returned from after using
+`Info-history-back' (renamed from `Info-last').
+
+*** New command `Info-history' (bound to L) displays a menu of visited nodes.
+
+*** New command `Info-toc' (bound to T) creates a node with table of contents
+from the tree structure of menus of the current Info file.
+
+*** New command `Info-copy-current-node-name' (bound to w) copies
+the current Info node name into the kill ring. With a zero prefix
+arg, puts the node name inside the `info' function call.
+
+*** New face `info-xref-visited' distinguishes visited nodes from unvisited
+and a new option `Info-fontify-visited-nodes' to control this.
+
+*** A numeric prefix argument of `info' selects an Info buffer
+with the number appended to the `*info*' buffer name (e.g. "*info*<2>").
+
+*** Info now hides node names in menus and cross references by default.
+
+If you prefer the old behavior, you can set the new user option
+`Info-hide-note-references' to nil.
+
+*** The default value for `Info-scroll-prefer-subnodes' is now nil.
+
+** Emacs server changes
+
+*** You can have several Emacs servers on the same machine.
+
+ % emacs --eval '(setq server-name "foo")' -f server-start &
+ % emacs --eval '(setq server-name "bar")' -f server-start &
+ % emacsclient -s foo file1
+ % emacsclient -s bar file2
+
+*** The `emacsclient' command understands the options `--eval' and
+`--display' which tell Emacs respectively to evaluate the given Lisp
+expression and to use the given display when visiting files.
+
+*** User option `server-mode' can be used to start a server process.
+
+** Locate changes
+
+*** By default, reverting the *Locate* buffer now just runs the last
+`locate' command back over again without offering to update the locate
+database (which normally only works if you have root privileges). If
+you prefer the old behavior, set the new customizable option
+`locate-update-when-revert' to t.
+
+** Desktop package
+
+*** Desktop saving is now a minor mode, `desktop-save-mode'.
+
+*** The variable `desktop-enable' is obsolete.
+
+Customize `desktop-save-mode' to enable desktop saving.
+
+*** Buffers are saved in the desktop file in the same order as that in the
+buffer list.
+
+*** The desktop package can be customized to restore only some buffers
+immediately, remaining buffers are restored lazily (when Emacs is
+idle).
+
+*** New command line option --no-desktop
+
+*** New commands:
+ - desktop-revert reverts to the last loaded desktop.
+ - desktop-change-dir kills current desktop and loads a new.
+ - desktop-save-in-desktop-dir saves desktop in the directory from which
+ it was loaded.
+ - desktop-lazy-complete runs the desktop load to completion.
+ - desktop-lazy-abort aborts lazy loading of the desktop.
+
+*** New customizable variables:
+ - desktop-save. Determines whether the desktop should be saved when it is
+ killed.
+ - desktop-file-name-format. Format in which desktop file names should be saved.
+ - desktop-path. List of directories in which to lookup the desktop file.
+ - desktop-locals-to-save. List of local variables to save.
+ - desktop-globals-to-clear. List of global variables that `desktop-clear' will clear.
+ - desktop-clear-preserve-buffers-regexp. Regexp identifying buffers that `desktop-clear'
+ should not delete.
+ - desktop-restore-eager. Number of buffers to restore immediately. Remaining buffers are
+ restored lazily (when Emacs is idle).
+ - desktop-lazy-verbose. Verbose reporting of lazily created buffers.
+ - desktop-lazy-idle-delay. Idle delay before starting to create buffers.
+
+*** New hooks:
+ - desktop-after-read-hook run after a desktop is loaded.
+ - desktop-no-desktop-file-hook run when no desktop file is found.
+
+** Recentf changes
+
+The recent file list is now automatically cleaned up when recentf mode is
+enabled. The new option `recentf-auto-cleanup' controls when to do
+automatic cleanup.
+
+The ten most recent files can be quickly opened by using the shortcut
+keys 1 to 9, and 0, when the recent list is displayed in a buffer via
+the `recentf-open-files', or `recentf-open-more-files' commands.
+
+The `recentf-keep' option replaces `recentf-keep-non-readable-files-p'
+and provides a more general mechanism to customize which file names to
+keep in the recent list.
+
+With the more advanced option `recentf-filename-handlers', you can
+specify functions that successively transform recent file names. For
+example, if set to `file-truename' plus `abbreviate-file-name', the
+same file will not be in the recent list with different symbolic
+links, and the file name will be abbreviated.
+
+To follow naming convention, `recentf-menu-append-commands-flag'
+replaces the misnamed option `recentf-menu-append-commands-p'. The
+old name remains available as alias, but has been marked obsolete.
+
+** Auto-Revert changes
+
+*** You can now use Auto Revert mode to `tail' a file.
+
+If point is at the end of a file buffer before reverting, Auto Revert
+mode keeps it at the end after reverting. Similarly if point is
+displayed at the end of a file buffer in any window, it stays at the end
+of the buffer in that window. This allows you to "tail" a file: just
+put point at the end of the buffer and it stays there. This rule
+applies to file buffers. For non-file buffers, the behavior can be mode
+dependent.
+
+If you are sure that the file will only change by growing at the end,
+then you can tail the file more efficiently by using the new minor
+mode Auto Revert Tail mode. The function `auto-revert-tail-mode'
+toggles this mode.
+
+*** Auto Revert mode is now more careful to avoid excessive reverts and
+other potential problems when deciding which non-file buffers to
+revert. This matters especially if Global Auto Revert mode is enabled
+and `global-auto-revert-non-file-buffers' is non-nil. Auto Revert
+mode only reverts a non-file buffer if the buffer has a non-nil
+`revert-buffer-function' and a non-nil `buffer-stale-function', which
+decides whether the buffer should be reverted. Currently, this means
+that auto reverting works for Dired buffers (although this may not
+work properly on all operating systems) and for the Buffer Menu.
+
+*** If the new user option `auto-revert-check-vc-info' is non-nil, Auto
+Revert mode reliably updates version control info (such as the version
+control number in the mode line), in all version controlled buffers in
+which it is active. If the option is nil, the default, then this info
+only gets updated whenever the buffer gets reverted.
+
+** Changes in Shell Mode
+
+*** Shell output normally scrolls so that the input line is at the
+bottom of the window -- thus showing the maximum possible text. (This
+is similar to the way sequential output to a terminal works.)
+
+** Changes in Hi Lock
+
+*** hi-lock-mode now only affects a single buffer, and a new function
+`global-hi-lock-mode' enables Hi Lock in all buffers. By default, if
+hi-lock-mode is used in what appears to be the initialization file, a
+warning message suggests to use global-hi-lock-mode instead. However,
+if the new variable `hi-lock-archaic-interface-deduce' is non-nil,
+using hi-lock-mode in an initialization file will turn on Hi Lock in all
+buffers and no warning will be issued (for compatibility with the
+behavior in older versions of Emacs).
+
+** Changes in Allout
+
+*** Topic cryptography added, enabling easy gpg topic encryption and
+decryption. Per-topic basis enables interspersing encrypted-text and
+clear-text within a single file to your heart's content, using symmetric
+and/or public key modes. Time-limited key caching, user-provided
+symmetric key hinting and consistency verification, auto-encryption of
+pending topics on save, and more, make it easy to use encryption in
+powerful ways. Encryption behavior customization is collected in the
+allout-encryption customization group.
+
+*** Default command prefix was changed to "\C-c " (control-c space), to
+avoid intruding on user's keybinding space. Customize the
+`allout-command-prefix' variable to your preference.
+
+*** Some previously rough topic-header format edge cases are reconciled.
+Level 1 topics use the mode's comment format, and lines starting with the
+asterisk - for instance, the comment close of some languages (eg, c's "*/"
+or mathematica's "*)") - at the beginning of line are no longer are
+interpreted as level 1 topics in those modes.
+
+*** Many or most commonly occurring "accidental" topics are disqualified.
+Text in item bodies that looks like a low-depth topic is no longer mistaken
+for one unless its first offspring (or that of its next sibling with
+offspring) is only one level deeper.
+
+For example, pasting some text with a bunch of leading asterisks into a
+topic that's followed by a level 3 or deeper topic will not cause the
+pasted text to be mistaken for outline structure.
+
+The same constraint is applied to any level 2 or 3 topics.
+
+This settles an old issue where typed or pasted text needed to be carefully
+reviewed, and sometimes doctored, to avoid accidentally disrupting the
+outline structure. Now that should be generally unnecessary, as the most
+prone-to-occur accidents are disqualified.
+
+*** Allout now refuses to create "containment discontinuities", where a
+topic is shifted deeper than the offspring-depth of its container. On the
+other hand, allout now operates gracefully with existing containment
+discontinuities, revealing excessively contained topics rather than either
+leaving them hidden or raising an error.
+
+*** Navigation within an item is easier. Repeated beginning-of-line and
+end-of-line key commands (usually, ^A and ^E) cycle through the
+beginning/end-of-line and then beginning/end of topic, etc. See new
+customization vars `allout-beginning-of-line-cycles' and
+`allout-end-of-line-cycles'.
+
+*** New or revised allout-mode activity hooks enable creation of
+cooperative enhancements to allout mode without changes to the mode,
+itself.
+
+See `allout-exposure-change-hook', `allout-structure-added-hook',
+`allout-structure-deleted-hook', and `allout-structure-shifted-hook'.
+
+`allout-exposure-change-hook' replaces the existing
+`allout-view-change-hook', which is being deprecated. Both are still
+invoked, but `allout-view-change-hook' will eventually be ignored.
+`allout-exposure-change-hook' is called with explicit arguments detailing
+the specifics of each change (as are the other new hooks), making it easier
+to use than the old version.
+
+There is a new mode deactivation hook, `allout-mode-deactivate-hook', for
+coordinating with deactivation of allout-mode. Both that and the mode
+activation hook, `allout-mode-hook' are now run after the `allout-mode'
+variable is changed, rather than before.
+
+*** Allout now uses text overlay's `invisible' property for concealed text,
+instead of selective-display. This simplifies the code, in particular
+avoiding the need for kludges for isearch dynamic-display, discretionary
+handling of edits of concealed text, undo concerns, etc.
+
+*** There are many other fixes and refinements, including:
+
+ - repaired inhibition of inadvertent edits to concealed text, without
+ inhibiting undo; we now reveal undo changes within concealed text.
+ - auto-fill-mode is now left inactive when allout-mode starts, if it
+ already was inactive. also, `allout-inhibit-auto-fill' custom
+ configuration variable makes it easy to disable auto fill in allout
+ outlines in general or on a per-buffer basis.
+ - allout now tolerates fielded text in outlines without disruption.
+ - hot-spot navigation now is modularized with a new function,
+ `allout-hotspot-key-handler', enabling easier use and enhancement of
+ the functionality in allout addons.
+ - repaired retention of topic body hanging indent upon topic depth shifts
+ - bulleting variation is simpler and more accommodating, both in the
+ default behavior and in ability to vary when creating new topics
+ - mode deactivation now does cleans up effectively, more properly
+ restoring affected variables and hooks to former state, removing
+ overlays, etc. see `allout-add-resumptions' and
+ `allout-do-resumptions', which replace the old `allout-resumptions'.
+ - included a few unit-tests for interior functionality. developers can
+ have them automatically run at the end of module load by customizing
+ the option `allout-run-unit-tests-on-load'.
+ - many, many other, more minor tweaks, fixes, and refinements.
+ - version number incremented to 2.2
+
+** Hideshow mode changes
+
+*** New variable `hs-set-up-overlay' allows customization of the overlay
+used to effect hiding for hideshow minor mode. Integration with isearch
+handles the overlay property `display' specially, preserving it during
+temporary overlay showing in the course of an isearch operation.
+
+*** New variable `hs-allow-nesting' non-nil means that hiding a block does
+not discard the hidden state of any "internal" blocks; when the parent
+block is later shown, the internal blocks remain hidden. Default is nil.
+
+** FFAP changes
+
+*** New ffap commands and keybindings:
+
+C-x C-r (`ffap-read-only'),
+C-x C-v (`ffap-alternate-file'), C-x C-d (`ffap-list-directory'),
+C-x 4 r (`ffap-read-only-other-window'), C-x 4 d (`ffap-dired-other-window'),
+C-x 5 r (`ffap-read-only-other-frame'), C-x 5 d (`ffap-dired-other-frame').
+
+*** FFAP accepts wildcards in a file name by default.
+
+C-x C-f passes the file name to `find-file' with non-nil WILDCARDS
+argument, which visits multiple files, and C-x d passes it to `dired'.
+
+** Changes in Skeleton
+
+*** In skeleton.el, `-' marks the `skeleton-point' without interregion interaction.
+
+`@' has reverted to only setting `skeleton-positions' and no longer
+sets `skeleton-point'. Skeletons which used @ to mark
+`skeleton-point' independent of `_' should now use `-' instead. The
+updated `skeleton-insert' docstring explains these new features along
+with other details of skeleton construction.
+
+*** The variables `skeleton-transformation', `skeleton-filter', and
+`skeleton-pair-filter' have been renamed to
+`skeleton-transformation-function', `skeleton-filter-function', and
+`skeleton-pair-filter-function'. The old names are still available
+as aliases.
+
+** HTML/SGML changes
+
+*** Emacs now tries to set up buffer coding systems for HTML/XML files
+automatically.
+
+*** SGML mode has indentation and supports XML syntax.
+The new variable `sgml-xml-mode' tells SGML mode to use XML syntax.
+When this option is enabled, SGML tags are inserted in XML style,
+i.e., there is always a closing tag.
+By default, its setting is inferred on a buffer-by-buffer basis
+from the file name or buffer contents.
+
+*** The variable `sgml-transformation' has been renamed to
+`sgml-transformation-function'. The old name is still available as
+alias.
+
+*** `xml-mode' is now an alias for `sgml-mode', which has XML support.
+
+** TeX modes
+
+*** New major mode Doctex mode, for *.dtx files.
+
+*** C-c C-c prompts for a command to run, and tries to offer a good default.
+
+*** The user option `tex-start-options-string' has been replaced
+by two new user options: `tex-start-options', which should hold
+command-line options to feed to TeX, and `tex-start-commands' which should hold
+TeX commands to use at startup.
+
+*** verbatim environments are now highlighted in courier by font-lock
+and super/sub-scripts are made into super/sub-scripts.
+
+** RefTeX mode changes
+
+*** Changes to RefTeX's table of contents
+
+The new command keys "<" and ">" in the TOC buffer promote/demote the
+section at point or all sections in the current region, with full
+support for multifile documents.
+
+The new command `reftex-toc-recenter' (`C-c -') shows the current
+section in the TOC buffer without selecting the TOC window.
+Recentering can happen automatically in idle time when the option
+`reftex-auto-recenter-toc' is turned on. The highlight in the TOC
+buffer stays when the focus moves to a different window. A dedicated
+frame can show the TOC with the current section always automatically
+highlighted. The frame is created and deleted from the toc buffer
+with the `d' key.
+
+The toc window can be split off horizontally instead of vertically.
+See new option `reftex-toc-split-windows-horizontally'.
+
+Labels can be renamed globally from the table of contents using the
+key `M-%'.
+
+The new command `reftex-goto-label' jumps directly to a label
+location.
+
+*** Changes related to citations and BibTeX database files
+
+Commands that insert a citation now prompt for optional arguments when
+called with a prefix argument. Related new options are
+`reftex-cite-prompt-optional-args' and `reftex-cite-cleanup-optional-args'.
+
+The new command `reftex-create-bibtex-file' creates a BibTeX database
+with all entries referenced in the current document. The keys "e" and
+"E" allow to produce a BibTeX database file from entries marked in a
+citation selection buffer.
+
+The command `reftex-citation' uses the word in the buffer before the
+cursor as a default search string.
+
+The support for chapterbib has been improved. Different chapters can
+now use BibTeX or an explicit `thebibliography' environment.
+
+The macros which specify the bibliography file (like \bibliography)
+can be configured with the new option `reftex-bibliography-commands'.
+
+Support for jurabib has been added.
+
+*** Global index matched may be verified with a user function.
+
+During global indexing, a user function can verify an index match.
+See new option `reftex-index-verify-function'.
+
+*** Parsing documents with many labels can be sped up.
+
+Operating in a document with thousands of labels can be sped up
+considerably by allowing RefTeX to derive the type of a label directly
+from the label prefix like `eq:' or `fig:'. The option
+`reftex-trust-label-prefix' needs to be configured in order to enable
+this feature. While the speed-up is significant, this may reduce the
+quality of the context offered by RefTeX to describe a label.
+
+*** Miscellaneous changes
+
+The macros which input a file in LaTeX (like \input, \include) can be
+configured in the new option `reftex-include-file-commands'.
+
+RefTeX supports global incremental search.
+
+** BibTeX mode
+
+*** The new command `bibtex-url' browses a URL for the BibTeX entry at
+point (bound to C-c C-l and mouse-2, RET on clickable fields).
+
+*** The new command `bibtex-entry-update' (bound to C-c C-u) updates
+an existing BibTeX entry by inserting fields that may occur but are not
+present.
+
+*** New `bibtex-entry-format' option `required-fields', enabled by default.
+
+*** `bibtex-maintain-sorted-entries' can take values `plain',
+`crossref', and `entry-class' which control the sorting scheme used
+for BibTeX entries. `bibtex-sort-entry-class' controls the sorting
+scheme `entry-class'. TAB completion for reference keys and
+automatic detection of duplicates does not require anymore that
+`bibtex-maintain-sorted-entries' is non-nil.
+
+*** The new command `bibtex-complete' completes word fragment before
+point according to context (bound to M-tab).
+
+*** In BibTeX mode the command `fill-paragraph' (M-q) fills
+individual fields of a BibTeX entry.
+
+*** The new variable `bibtex-autofill-types' contains a list of entry
+types for which fields are filled automatically (if possible).
+
+*** The new commands `bibtex-find-entry' and `bibtex-find-crossref'
+locate entries and crossref'd entries (bound to C-c C-s and C-c C-x).
+Crossref fields are clickable (bound to mouse-2, RET).
+
+*** The new variables `bibtex-files' and `bibtex-file-path' define a set
+of BibTeX files that are searched for entry keys.
+
+*** The new command `bibtex-validate-globally' checks for duplicate keys
+in multiple BibTeX files.
+
+*** If the new variable `bibtex-autoadd-commas' is non-nil,
+automatically add missing commas at end of BibTeX fields.
+
+*** The new command `bibtex-copy-summary-as-kill' pushes summary
+of BibTeX entry to kill ring (bound to C-c C-t).
+
+*** If the new variable `bibtex-parse-keys-fast' is non-nil,
+use fast but simplified algorithm for parsing BibTeX keys.
+
+*** The new variables bibtex-expand-strings and
+bibtex-autokey-expand-strings control the expansion of strings when
+extracting the content of a BibTeX field.
+
+*** The variables `bibtex-autokey-name-case-convert' and
+`bibtex-autokey-titleword-case-convert' have been renamed to
+`bibtex-autokey-name-case-convert-function' and
+`bibtex-autokey-titleword-case-convert-function'. The old names are
+still available as aliases.
+
+** GUD changes
+
+*** The new package gdb-ui.el provides an enhanced graphical interface to
+GDB. You can interact with GDB through the GUD buffer in the usual way, but
+there are also further buffers which control the execution and describe the
+state of your program. It can separate the input/output of your program from
+that of GDB and watches expressions in the speedbar. It also uses features of
+Emacs 21/22 such as the toolbar, and bitmaps in the fringe to indicate
+breakpoints.
+
+To use this package just type M-x gdb. See the Emacs manual if you want the
+old behaviour.
+
+*** GUD mode has its own tool bar for controlling execution of the inferior
+and other common debugger commands.
+
+*** In GUD mode, when talking to GDB, C-x C-a C-j "jumps" the program
+counter to the specified source line (the one where point is).
+
+*** The variable tooltip-gud-tips-p has been removed. GUD tooltips can now be
+toggled independently of normal tooltips with the minor mode
+`gud-tooltip-mode'.
+
+*** In graphical mode, with a C program, GUD Tooltips have been extended to
+display the #define directive associated with an identifier when program is
+not executing.
+
+*** GUD mode improvements for jdb:
+
+**** Search for source files using jdb classpath and class information.
+Fast startup since there is no need to scan all source files up front.
+There is also no need to create and maintain lists of source
+directories to scan. Look at `gud-jdb-use-classpath' and
+`gud-jdb-classpath' customization variables documentation.
+
+**** The previous method of searching for source files has been
+preserved in case someone still wants/needs to use it.
+Set `gud-jdb-use-classpath' to nil.
+
+**** Supports the standard breakpoint (gud-break, gud-clear)
+set/clear operations from Java source files under the classpath, stack
+traversal (gud-up, gud-down), and run until current stack finish
+(gud-finish).
+
+**** Supports new jdb (Java 1.2 and later) in addition to oldjdb
+(Java 1.1 jdb).
+
+*** Added jdb Customization Variables
+
+**** `gud-jdb-command-name'. What command line to use to invoke jdb.
+
+**** `gud-jdb-use-classpath'. Allows selection of java source file searching
+method: set to t for new method, nil to scan `gud-jdb-directories' for
+java sources (previous method).
+
+**** `gud-jdb-directories'. List of directories to scan and search for Java
+classes using the original gud-jdb method (if `gud-jdb-use-classpath'
+is nil).
+
+*** Minor Improvements
+
+**** The STARTTLS wrapper (starttls.el) can now use GNUTLS
+instead of the OpenSSL based `starttls' tool. For backwards
+compatibility, it prefers `starttls', but you can toggle
+`starttls-use-gnutls' to switch to GNUTLS (or simply remove the
+`starttls' tool).
+
+**** Do not allow debugger output history variable to grow without bounds.
+
+** Lisp mode changes
+
+*** Lisp mode now uses `font-lock-doc-face' for doc strings.
+
+*** C-u C-M-q in Emacs Lisp mode pretty-prints the list after point.
+
+*** New features in evaluation commands
+
+**** The function `eval-defun' (C-M-x) called on defface reinitializes
+the face to the value specified in the defface expression.
+
+**** Typing C-x C-e twice prints the value of the integer result
+in additional formats (octal, hexadecimal, character) specified
+by the new function `eval-expression-print-format'. The same
+function also defines the result format for `eval-expression' (M-:),
+`eval-print-last-sexp' (C-j) and some edebug evaluation functions.
+
+** Changes to cmuscheme
+
+*** Emacs now offers to start Scheme if the user tries to
+evaluate a Scheme expression but no Scheme subprocess is running.
+
+*** If the file ~/.emacs_NAME or ~/.emacs.d/init_NAME.scm (where NAME
+is the name of the Scheme interpreter) exists, its contents are sent
+to the Scheme subprocess upon startup.
+
+*** There are new commands to instruct the Scheme interpreter to trace
+procedure calls (`scheme-trace-procedure') and to expand syntactic forms
+(`scheme-expand-current-form'). The commands actually sent to the Scheme
+subprocess are controlled by the user options `scheme-trace-command',
+`scheme-untrace-command' and `scheme-expand-current-form'.
+
+** Ewoc changes
+
+*** The new function `ewoc-delete' deletes specified nodes.
+
+*** `ewoc-create' now takes optional arg NOSEP, which inhibits insertion of
+a newline after each pretty-printed entry and after the header and footer.
+This allows you to create multiple-entry ewocs on a single line and to
+effect "invisible" nodes by arranging for the pretty-printer to not print
+anything for those nodes.
+
+For example, these two sequences of expressions behave identically:
+
+;; NOSEP nil
+(defun PP (data) (insert (format "%S" data)))
+(ewoc-create 'PP "start\n")
+
+;; NOSEP t
+(defun PP (data) (insert (format "%S\n" data)))
+(ewoc-create 'PP "start\n\n" "\n" t)
+
+** CC mode changes
+
+*** The CC Mode manual has been extensively revised.
+The information about using CC Mode has been separated from the larger
+and more difficult chapters about configuration.
+
+*** New Minor Modes
+**** Electric Minor Mode toggles the electric action of non-alphabetic keys.
+The new command c-toggle-electric-mode is bound to C-c C-l. Turning the
+mode off can be helpful for editing chaotically indented code and for
+users new to CC Mode, who sometimes find electric indentation
+disconcerting. Its current state is displayed in the mode line with an
+'l', e.g. "C/al".
+
+**** Subword Minor Mode makes Emacs recognize word boundaries at upper case
+letters in StudlyCapsIdentifiers. You enable this feature by C-c C-w. It can
+also be used in non-CC Mode buffers. :-) Contributed by Masatake YAMATO.
+
+*** Support for the AWK language.
+Support for the AWK language has been introduced. The implementation is
+based around GNU AWK version 3.1, but it should work pretty well with
+any AWK. As yet, not all features of CC Mode have been adapted for AWK.
+Here is a summary:
+
+**** Indentation Engine
+The CC Mode indentation engine fully supports AWK mode.
+
+AWK mode handles code formatted in the conventional AWK fashion: `{'s
+which start actions, user-defined functions, or compound statements are
+placed on the same line as the associated construct; the matching `}'s
+are normally placed under the start of the respective pattern, function
+definition, or structured statement.
+
+The predefined line-up functions haven't yet been adapted for AWK
+mode, though some of them may work serendipitously. There shouldn't
+be any problems writing custom indentation functions for AWK mode.
+
+**** Font Locking
+There is a single level of font locking in AWK mode, rather than the
+three distinct levels the other modes have. There are several
+idiosyncrasies in AWK mode's font-locking due to the peculiarities of
+the AWK language itself.
+
+**** Comment and Movement Commands
+These commands all work for AWK buffers. The notion of "defun" has
+been augmented to include AWK pattern-action pairs - the standard
+"defun" commands on key sequences C-M-a, C-M-e, and C-M-h use this
+extended definition.
+
+**** "awk" style, Auto-newline Insertion and Clean-ups
+A new style, "awk" has been introduced, and this is now the default
+style for AWK code. With auto-newline enabled, the clean-up
+c-one-liner-defun (see above) is useful.
+
+*** Font lock support.
+CC Mode now provides font lock support for all its languages. This
+supersedes the font lock patterns that have been in the core font lock
+package for C, C++, Java and Objective-C. Like indentation, font
+locking is done in a uniform way across all languages (except the new
+AWK mode - see below). That means that the new font locking will be
+different from the old patterns in various details for most languages.
+
+The main goal of the font locking in CC Mode is accuracy, to provide a
+dependable aid in recognizing the various constructs. Some, like
+strings and comments, are easy to recognize while others like
+declarations and types can be very tricky. CC Mode can go to great
+lengths to recognize declarations and casts correctly, especially when
+the types aren't recognized by standard patterns. This is a fairly
+demanding analysis which can be slow on older hardware, and it can
+therefore be disabled by choosing a lower decoration level with the
+variable font-lock-maximum-decoration.
+
+Note that the most demanding font lock level has been tuned with lazy
+fontification in mind; Just-In-Time-Lock mode should be enabled for
+the highest font lock level (by default, it is). Fontifying a file
+with several thousand lines in one go can take the better part of a
+minute.
+
+**** The (c|c++|objc|java|idl|pike)-font-lock-extra-types variables
+are now used by CC Mode to recognize identifiers that are certain to
+be types. (They are also used in cases that aren't related to font
+locking.) At the maximum decoration level, types are often recognized
+properly anyway, so these variables should be fairly restrictive and
+not contain patterns for uncertain types.
+
+**** Support for documentation comments.
+There is a "plugin" system to fontify documentation comments like
+Javadoc and the markup within them. It's independent of the host
+language, so it's possible to e.g. turn on Javadoc font locking in C
+buffers. See the variable c-doc-comment-style for details.
+
+Currently three kinds of doc comment styles are recognized: Sun's
+Javadoc, Autodoc (which is used in Pike) and GtkDoc (used in C). (The
+last was contributed by Masatake YAMATO). This is by no means a
+complete list of the most common tools; if your doc comment extractor
+of choice is missing then please drop a note to bug-cc-mode@gnu.org.
+
+**** Better handling of C++ templates.
+As a side effect of the more accurate font locking, C++ templates are
+now handled much better. The angle brackets that delimit them are
+given parenthesis syntax so that they can be navigated like other
+parens.
+
+This also improves indentation of templates, although there still is
+work to be done in that area. E.g. it's required that multiline
+template clauses are written in full and then refontified to be
+recognized, and the indentation of nested templates is a bit odd and
+not as configurable as it ought to be.
+
+**** Improved handling of Objective-C and CORBA IDL.
+Especially the support for Objective-C and IDL has gotten an overhaul.
+The special "@" declarations in Objective-C are handled correctly.
+All the keywords used in CORBA IDL, PSDL, and CIDL are recognized and
+handled correctly, also wrt indentation.
+
+*** Changes in Key Sequences
+**** c-toggle-auto-hungry-state is no longer bound to C-c C-t.
+
+**** c-toggle-hungry-state is no longer bound to C-c C-d.
+This binding has been taken over by c-hungry-delete-forwards.
+
+**** c-toggle-auto-state (C-c C-t) has been renamed to c-toggle-auto-newline.
+c-toggle-auto-state remains as an alias.
+
+**** The new commands c-hungry-backspace and c-hungry-delete-forwards
+have key bindings C-c C-DEL (or C-c DEL, for the benefit of TTYs) and
+C-c C-d (or C-c C-<delete> or C-c <delete>) respectively. These
+commands delete entire blocks of whitespace with a single
+key-sequence. [N.B. "DEL" is the <backspace> key.]
+
+**** The new command c-toggle-electric-mode is bound to C-c C-l.
+
+**** The new command c-subword-mode is bound to C-c C-w.
+
+*** C-c C-s (`c-show-syntactic-information') now highlights the anchor
+position(s).
+
+*** New syntactic symbols in IDL mode.
+The top level constructs "module" and "composition" (from CIDL) are
+now handled like "namespace" in C++: They are given syntactic symbols
+module-open, module-close, inmodule, composition-open,
+composition-close, and incomposition.
+
+*** New functions to do hungry delete without enabling hungry delete mode.
+The new functions `c-hungry-backspace' and `c-hungry-delete-forward'
+provide hungry deletion without having to toggle a mode. They are
+bound to C-c C-DEL and C-c C-d (and several variants, for the benefit
+of different keyboard setups. See "Changes in key sequences" above).
+
+*** Better control over `require-final-newline'.
+
+The variable `c-require-final-newline' specifies which of the modes
+implemented by CC mode should insert final newlines. Its value is a
+list of modes, and only those modes should do it. By default the list
+includes C, C++ and Objective-C modes.
+
+Whichever modes are in this list will set `require-final-newline'
+based on `mode-require-final-newline'.
+
+*** Format change for syntactic context elements.
+
+The elements in the syntactic context returned by `c-guess-basic-syntax'
+and stored in `c-syntactic-context' has been changed somewhat to allow
+attaching more information. They are now lists instead of single cons
+cells. E.g. a line that previously had the syntactic analysis
+
+((inclass . 11) (topmost-intro . 13))
+
+is now analyzed as
+
+((inclass 11) (topmost-intro 13))
+
+In some cases there are more than one position given for a syntactic
+symbol.
+
+This change might affect code that calls `c-guess-basic-syntax'
+directly, and custom lineup functions if they use
+`c-syntactic-context'. However, the argument given to lineup
+functions is still a single cons cell with nil or an integer in the
+cdr.
+
+*** API changes for derived modes.
+
+There have been extensive changes "under the hood" which can affect
+derived mode writers. Some of these changes are likely to cause
+incompatibilities with existing derived modes, but on the other hand
+care has now been taken to make it possible to extend and modify CC
+Mode with less risk of such problems in the future.
+
+**** New language variable system.
+These are variables whose values vary between CC Mode's different
+languages. See the comment blurb near the top of cc-langs.el.
+
+**** New initialization functions.
+The initialization procedure has been split up into more functions to
+give better control: `c-basic-common-init', `c-font-lock-init', and
+`c-init-language-vars'.
+
+*** Changes in analysis of nested syntactic constructs.
+The syntactic analysis engine has better handling of cases where
+several syntactic constructs appear nested on the same line. They are
+now handled as if each construct started on a line of its own.
+
+This means that CC Mode now indents some cases differently, and
+although it's more consistent there might be cases where the old way
+gave results that's more to one's liking. So if you find a situation
+where you think that the indentation has become worse, please report
+it to bug-cc-mode@gnu.org.
+
+**** New syntactic symbol substatement-label.
+This symbol is used when a label is inserted between a statement and
+its substatement. E.g:
+
+ if (x)
+ x_is_true:
+ do_stuff();
+
+*** Better handling of multiline macros.
+
+**** Syntactic indentation inside macros.
+The contents of multiline #define's are now analyzed and indented
+syntactically just like other code. This can be disabled by the new
+variable `c-syntactic-indentation-in-macros'. A new syntactic symbol
+`cpp-define-intro' has been added to control the initial indentation
+inside `#define's.
+
+**** New lineup function `c-lineup-cpp-define'.
+
+Now used by default to line up macro continuation lines. The behavior
+of this function closely mimics the indentation one gets if the macro
+is indented while the line continuation backslashes are temporarily
+removed. If syntactic indentation in macros is turned off, it works
+much line `c-lineup-dont-change', which was used earlier, but handles
+empty lines within the macro better.
+
+**** Automatically inserted newlines continues the macro if used within one.
+This applies to the newlines inserted by the auto-newline mode, and to
+`c-context-line-break' and `c-context-open-line'.
+
+**** Better alignment of line continuation backslashes.
+`c-backslash-region' tries to adapt to surrounding backslashes. New
+variable `c-backslash-max-column' puts a limit on how far out
+backslashes can be moved.
+
+**** Automatic alignment of line continuation backslashes.
+This is controlled by the new variable `c-auto-align-backslashes'. It
+affects `c-context-line-break', `c-context-open-line' and newlines
+inserted in Auto-Newline mode.
+
+**** Line indentation works better inside macros.
+Regardless whether syntactic indentation and syntactic indentation
+inside macros are enabled or not, line indentation now ignores the
+line continuation backslashes. This is most noticeable when syntactic
+indentation is turned off and there are empty lines (save for the
+backslash) in the macro.
+
+*** indent-for-comment is more customizable.
+The behavior of M-; (indent-for-comment) is now configurable through
+the variable `c-indent-comment-alist'. The indentation behavior is
+based on the preceding code on the line, e.g. to get two spaces after
+#else and #endif but indentation to `comment-column' in most other
+cases (something which was hardcoded earlier).
+
+*** New function `c-context-open-line'.
+It's the open-line equivalent of `c-context-line-break'.
+
+*** New clean-ups
+
+**** `comment-close-slash'.
+With this clean-up, a block (i.e. c-style) comment can be terminated by
+typing a slash at the start of a line.
+
+**** `c-one-liner-defun'
+This clean-up compresses a short enough defun (for example, an AWK
+pattern/action pair) onto a single line. "Short enough" is configurable.
+
+*** New lineup functions
+
+**** `c-lineup-string-cont'
+This lineup function lines up a continued string under the one it
+continues. E.g:
+
+result = prefix + "A message "
+ "string."; <- c-lineup-string-cont
+
+**** `c-lineup-cascaded-calls'
+Lines up series of calls separated by "->" or ".".
+
+**** `c-lineup-knr-region-comment'
+Gives (what most people think is) better indentation of comments in
+the "K&R region" between the function header and its body.
+
+**** `c-lineup-gcc-asm-reg'
+Provides better indentation inside asm blocks.
+
+**** `c-lineup-argcont'
+Lines up continued function arguments after the preceding comma.
+
+*** Added toggle for syntactic indentation.
+The function `c-toggle-syntactic-indentation' can be used to toggle
+syntactic indentation.
+
+*** Better caching of the syntactic context.
+CC Mode caches the positions of the opening parentheses (of any kind)
+of the lists surrounding the point. Those positions are used in many
+places as anchor points for various searches. The cache is now
+improved so that it can be reused to a large extent when the point is
+moved. The less it moves, the less needs to be recalculated.
+
+The effect is that CC Mode should be fast most of the time even when
+opening parens are hung (i.e. aren't in column zero). It's typically
+only the first time after the point is moved far down in a complex
+file that it'll take noticeable time to find out the syntactic
+context.
+
+*** Statements are recognized in a more robust way.
+Statements are recognized most of the time even when they occur in an
+"invalid" context, e.g. in a function argument. In practice that can
+happen when macros are involved.
+
+*** Improved the way `c-indent-exp' chooses the block to indent.
+It now indents the block for the closest sexp following the point
+whose closing paren ends on a different line. This means that the
+point doesn't have to be immediately before the block to indent.
+Also, only the block and the closing line is indented; the current
+line is left untouched.
+
+** Changes in Makefile mode
+
+*** Makefile mode has submodes for automake, gmake, makepp, BSD make and imake.
+
+The former two couldn't be differentiated before, and the latter three
+are new. Font-locking is robust now and offers new customizable
+faces.
+
+*** The variable `makefile-query-one-target-method' has been renamed
+to `makefile-query-one-target-method-function'. The old name is still
+available as alias.
+
+** Sql changes
+
+*** The variable `sql-product' controls the highlighting of different
+SQL dialects. This variable can be set globally via Customize, on a
+buffer-specific basis via local variable settings, or for the current
+session using the new SQL->Product submenu. (This menu replaces the
+SQL->Highlighting submenu.)
+
+The following values are supported:
+
+ ansi ANSI Standard (default)
+ db2 DB2
+ informix Informix
+ ingres Ingres
+ interbase Interbase
+ linter Linter
+ ms Microsoft
+ mysql MySQL
+ oracle Oracle
+ postgres Postgres
+ solid Solid
+ sqlite SQLite
+ sybase Sybase
+
+The current product name will be shown on the mode line following the
+SQL mode indicator.
+
+The technique of setting `sql-mode-font-lock-defaults' directly in
+your `.emacs' will no longer establish the default highlighting -- Use
+`sql-product' to accomplish this.
+
+ANSI keywords are always highlighted.
+
+*** The function `sql-add-product-keywords' can be used to add
+font-lock rules to the product specific rules. For example, to have
+all identifiers ending in `_t' under MS SQLServer treated as a type,
+you would use the following line in your .emacs file:
+
+ (sql-add-product-keywords 'ms
+ '(("\\<\\w+_t\\>" . font-lock-type-face)))
+
+*** Oracle support includes keyword highlighting for Oracle 9i.
+
+Most SQL and PL/SQL keywords are implemented. SQL*Plus commands are
+highlighted in `font-lock-doc-face'.
+
+*** Microsoft SQLServer support has been significantly improved.
+
+Keyword highlighting for SqlServer 2000 is implemented.
+sql-interactive-mode defaults to use osql, rather than isql, because
+osql flushes its error stream more frequently. Thus error messages
+are displayed when they occur rather than when the session is
+terminated.
+
+If the username and password are not provided to `sql-ms', osql is
+called with the `-E' command line argument to use the operating system
+credentials to authenticate the user.
+
+*** Postgres support is enhanced.
+Keyword highlighting of Postgres 7.3 is implemented. Prompting for
+the username and the pgsql `-U' option is added.
+
+*** MySQL support is enhanced.
+Keyword highlighting of MySql 4.0 is implemented.
+
+*** Imenu support has been enhanced to locate tables, views, indexes,
+packages, procedures, functions, triggers, sequences, rules, and
+defaults.
+
+*** Added SQL->Start SQLi Session menu entry which calls the
+appropriate `sql-interactive-mode' wrapper for the current setting of
+`sql-product'.
+
+*** sql.el supports the SQLite interpreter--call 'sql-sqlite'.
+
+** Fortran mode changes
+
+*** F90 mode and Fortran mode have support for `hs-minor-mode' (hideshow).
+It cannot deal with every code format, but ought to handle a sizeable
+majority.
+
+*** F90 mode and Fortran mode have new navigation commands
+`f90-end-of-block', `f90-beginning-of-block', `f90-next-block',
+`f90-previous-block', `fortran-end-of-block',
+`fortran-beginning-of-block'.
+
+*** Fortran mode does more font-locking by default. Use level 3
+highlighting for the old default.
+
+*** Fortran mode has a new variable `fortran-directive-re'.
+Adapt this to match the format of any compiler directives you use.
+Lines that match are never indented, and are given distinctive font-locking.
+
+*** The new function `f90-backslash-not-special' can be used to change
+the syntax of backslashes in F90 buffers.
+
+** Miscellaneous programming mode changes
+
+*** In sh-script, a continuation line is only indented if the backslash was
+preceded by a SPC or a TAB.
+
+*** Perl mode has a new variable `perl-indent-continued-arguments'.
+
+*** The old Octave mode bindings C-c f and C-c i have been changed
+to C-c C-f and C-c C-i. The C-c C-i subcommands now have duplicate
+bindings on control characters--thus, C-c C-i C-b is the same as
+C-c C-i b, and so on.
+
+*** Prolog mode has a new variable `prolog-font-lock-keywords'
+to support use of font-lock.
+
+** VC Changes
+
+*** New backends for Subversion and Meta-CVS.
+
+*** The new variable `vc-cvs-global-switches' specifies switches that
+are passed to any CVS command invoked by VC.
+
+These switches are used as "global options" for CVS, which means they
+are inserted before the command name. For example, this allows you to
+specify a compression level using the `-z#' option for CVS.
+
+*** The key C-x C-q only changes the read-only state of the buffer
+(toggle-read-only). It no longer checks files in or out.
+
+We made this change because we held a poll and found that many users
+were unhappy with the previous behavior. If you do prefer this
+behavior, you can bind `vc-toggle-read-only' to C-x C-q in your
+`.emacs' file:
+
+ (global-set-key "\C-x\C-q" 'vc-toggle-read-only)
+
+The function `vc-toggle-read-only' will continue to exist.
+
+*** VC-Annotate mode enhancements
+
+In VC-Annotate mode, you can now use the following key bindings for
+enhanced functionality to browse the annotations of past revisions, or
+to view diffs or log entries directly from vc-annotate-mode:
+
+ P: annotates the previous revision
+ N: annotates the next revision
+ J: annotates the revision at line
+ A: annotates the revision previous to line
+ D: shows the diff of the revision at line with its previous revision
+ L: shows the log of the revision at line
+ W: annotates the workfile (most up to date) version
+
+** pcl-cvs changes
+
+*** In pcl-cvs mode, there is a new `d y' command to view the diffs
+between the local version of the file and yesterday's head revision
+in the repository.
+
+*** In pcl-cvs mode, there is a new `d r' command to view the changes
+anyone has committed to the repository since you last executed
+`checkout', `update' or `commit'. That means using cvs diff options
+-rBASE -rHEAD.
+
+** Diff changes
+
+*** M-x diff uses Diff mode instead of Compilation mode.
+
+*** Diff mode key bindings changed.
+
+These are the new bindings:
+
+C-c C-e diff-ediff-patch (old M-A)
+C-c C-n diff-restrict-view (old M-r)
+C-c C-r diff-reverse-direction (old M-R)
+C-c C-u diff-context->unified (old M-U)
+C-c C-w diff-refine-hunk (old C-c C-r)
+
+To convert unified to context format, use C-u C-c C-u.
+In addition, C-c C-u now operates on the region
+in Transient Mark mode when the mark is active.
+
+** EDiff changes.
+
+*** When comparing directories.
+Typing D brings up a buffer that lists the differences between the contents of
+directories. Now it is possible to use this buffer to copy the missing files
+from one directory to another.
+
+*** When comparing files or buffers.
+Typing the = key now offers to perform the word-by-word comparison of the
+currently highlighted regions in an inferior Ediff session. If you answer 'n'
+then it reverts to the old behavior and asks the user to select regions for
+comparison.
+
+*** The new command `ediff-backup' compares a file with its most recent
+backup using `ediff'. If you specify the name of a backup file,
+`ediff-backup' compares it with the file of which it is a backup.
+
+** Etags changes.
+
+*** New regular expressions features
+
+**** New syntax for regular expressions, multi-line regular expressions.
+
+The syntax --ignore-case-regexp=/regex/ is now undocumented and retained
+only for backward compatibility. The new equivalent syntax is
+--regex=/regex/i. More generally, it is --regex=/TAGREGEX/TAGNAME/MODS,
+where `/TAGNAME' is optional, as usual, and MODS is a string of 0 or
+more characters among `i' (ignore case), `m' (multi-line) and `s'
+(single-line). The `m' and `s' modifiers behave as in Perl regular
+expressions: `m' allows regexps to match more than one line, while `s'
+(which implies `m') means that `.' matches newlines. The ability to
+span newlines allows writing of much more powerful regular expressions
+and rapid prototyping for tagging new languages.
+
+**** Regular expressions can use char escape sequences as in GCC.
+
+The escaped character sequence \a, \b, \d, \e, \f, \n, \r, \t, \v,
+respectively, stand for the ASCII characters BEL, BS, DEL, ESC, FF, NL,
+CR, TAB, VT.
+
+**** Regular expressions can be bound to a given language.
+
+The syntax --regex={LANGUAGE}REGEX means that REGEX is used to make tags
+only for files of language LANGUAGE, and ignored otherwise. This is
+particularly useful when storing regexps in a file.
+
+**** Regular expressions can be read from a file.
+
+The --regex=@regexfile option means read the regexps from a file, one
+per line. Lines beginning with space or tab are ignored.
+
+*** New language parsing features
+
+**** New language HTML.
+
+Tags are generated for `title' as well as `h1', `h2', and `h3'. Also,
+when `name=' is used inside an anchor and whenever `id=' is used.
+
+**** New language PHP.
+
+Functions, classes and defines are tags. If the --members option is
+specified to etags, variables are tags also.
+
+**** New language Lua.
+
+All functions are tagged.
+
+**** The `::' qualifier triggers C++ parsing in C file.
+
+Previously, only the `template' and `class' keywords had this effect.
+
+**** The GCC __attribute__ keyword is now recognized and ignored.
+
+**** In C and derived languages, etags creates tags for #undef
+
+**** In Makefiles, constants are tagged.
+
+If you want the old behavior instead, thus avoiding to increase the
+size of the tags file, use the --no-globals option.
+
+**** In Perl, packages are tags.
+
+Subroutine tags are named from their package. You can jump to sub tags
+as you did before, by the sub name, or additionally by looking for
+package::sub.
+
+**** In Prolog, etags creates tags for rules in addition to predicates.
+
+**** New default keywords for TeX.
+
+The new keywords are def, newcommand, renewcommand, newenvironment and
+renewenvironment.
+
+*** Honor #line directives.
+
+When Etags parses an input file that contains C preprocessor's #line
+directives, it creates tags using the file name and line number
+specified in those directives. This is useful when dealing with code
+created from Cweb source files. When Etags tags the generated file, it
+writes tags pointing to the source file.
+
+*** New option --parse-stdin=FILE.
+
+This option is mostly useful when calling etags from programs. It can
+be used (only once) in place of a file name on the command line. Etags
+reads from standard input and marks the produced tags as belonging to
+the file FILE.
+
+*** The --members option is now the default.
+
+Use --no-members if you want the old default behaviour of not tagging
+struct members in C, members variables in C++ and variables in PHP.
+
+** Ctags changes.
+
+*** Ctags now allows duplicate tags
+
+** Rmail changes
+
+*** Support for `movemail' from GNU mailutils was added to Rmail.
+
+This version of `movemail' allows you to read mail from a wide range of
+mailbox formats, including remote POP3 and IMAP4 mailboxes with or
+without TLS encryption. If GNU mailutils is installed on the system
+and its version of `movemail' can be found in exec-path, it will be
+used instead of the native one.
+
+*** The new commands rmail-end-of-message and rmail-summary end-of-message,
+by default bound to `/', go to the end of the current mail message in
+Rmail and Rmail summary buffers.
+
+*** Rmail now displays 5-digit message ids in its summary buffer.
+
+** Gnus package
+
+*** Gnus now includes Sieve and PGG
+
+Sieve is a library for managing Sieve scripts. PGG is a library to handle
+PGP/MIME.
+
+*** There are many news features, bug fixes and improvements.
+
+See the file GNUS-NEWS or the node "Oort Gnus" in the Gnus manual for details.
+
+** MH-E changes.
+
+Upgraded to MH-E version 8.0.3. There have been major changes since
+version 5.0.2; see MH-E-NEWS for details.
+
+** Miscellaneous mail changes
+
+*** The new variable `mail-default-directory' specifies
+`default-directory' for mail buffers. This directory is used for
+auto-save files of mail buffers. It defaults to "~/".
+
+*** The mode line can indicate new mail in a directory or file.
+
+See the documentation of the user option `display-time-mail-directory'.
+
+** Calendar changes
+
+*** There is a new calendar package, icalendar.el, that can be used to
+convert Emacs diary entries to/from the iCalendar format.
+
+*** The new package cal-html.el writes HTML files with calendar and
+diary entries.
+
+*** The new functions `diary-from-outlook', `diary-from-outlook-gnus',
+and `diary-from-outlook-rmail' can be used to import diary entries
+from Outlook-format appointments in mail messages. The variable
+`diary-outlook-formats' can be customized to recognize additional
+formats.
+
+*** The procedure for activating appointment reminders has changed:
+use the new function `appt-activate'. The new variable
+`appt-display-format' controls how reminders are displayed, replacing
+`appt-issue-message', `appt-visible', and `appt-msg-window'.
+
+*** The function `simple-diary-display' now by default sets a header line.
+This can be controlled through the variables `diary-header-line-flag'
+and `diary-header-line-format'.
+
+*** Diary sexp entries can have custom marking in the calendar.
+Diary sexp functions which only apply to certain days (such as
+`diary-block' or `diary-cyclic') now take an optional parameter MARK,
+which is the name of a face or a single-character string indicating
+how to highlight the day in the calendar display. Specifying a
+single-character string as @var{mark} places the character next to the
+day in the calendar. Specifying a face highlights the day with that
+face. This lets you have different colors or markings for vacations,
+appointments, paydays or anything else using a sexp.
+
+*** The meanings of C-x < and C-x > have been interchanged.
+< means to scroll backward in time, and > means to scroll forward.
+
+*** You can now use < and >, instead of C-x < and C-x >, to scroll
+the calendar left or right.
+
+*** The new function `calendar-goto-day-of-year' (g D) prompts for a
+year and day number, and moves to that date. Negative day numbers
+count backward from the end of the year.
+
+*** The new Calendar function `calendar-goto-iso-week' (g w)
+prompts for a year and a week number, and moves to the first
+day of that ISO week.
+
+*** The functions `holiday-easter-etc' and `holiday-advent' now take
+optional arguments, in order to only report on the specified holiday
+rather than all. This makes customization of variables such as
+`christian-holidays' simpler.
+
+*** The new variable `calendar-minimum-window-height' affects the
+window generated by the function `generate-calendar-window'.
+
+** Speedbar changes
+
+*** Speedbar items can now be selected by clicking mouse-1, based on
+the `mouse-1-click-follows-link' mechanism.
+
+*** The new command `speedbar-toggle-line-expansion', bound to SPC,
+contracts or expands the line under the cursor.
+
+*** New command `speedbar-create-directory', bound to `M'.
+
+*** The new commands `speedbar-expand-line-descendants' and
+`speedbar-contract-line-descendants', bound to `[' and `]'
+respectively, expand and contract the line under cursor with all of
+its descendents.
+
+*** The new user option `speedbar-use-tool-tips-flag', if non-nil,
+means to display tool-tips for speedbar items.
+
+*** The new user option `speedbar-query-confirmation-method' controls
+how querying is performed for file operations. A value of 'always
+means to always query before file operations; 'none-but-delete means
+to not query before any file operations, except before a file
+deletion.
+
+*** The new user option `speedbar-select-frame-method' specifies how
+to select a frame for displaying a file opened with the speedbar. A
+value of 'attached means to use the attached frame (the frame that
+speedbar was started from.) A number such as 1 or -1 means to pass
+that number to `other-frame'.
+
+*** SPC and DEL are no longer bound to scroll up/down in the speedbar
+keymap.
+
+*** The frame management code in speedbar.el has been split into a new
+`dframe' library. Emacs Lisp code that makes use of the speedbar
+should use `dframe-attached-frame' instead of
+`speedbar-attached-frame', `dframe-timer' instead of `speedbar-timer',
+`dframe-close-frame' instead of `speedbar-close-frame', and
+`dframe-activity-change-focus-flag' instead of
+`speedbar-activity-change-focus-flag'. The variables
+`speedbar-update-speed' and `speedbar-navigating-speed' are also
+obsolete; use `dframe-update-speed' instead.
+
+** battery.el changes
+
+*** display-battery-mode replaces display-battery.
+
+*** battery.el now works on recent versions of OS X.
+
+** Games
+
+*** The game `mpuz' is enhanced.
+
+`mpuz' now allows the 2nd factor not to have two identical digits. By
+default, all trivial operations involving whole lines are performed
+automatically. The game uses faces for better visual feedback.
+
+** Obsolete and deleted packages
+
+*** fast-lock.el and lazy-lock.el are obsolete. Use jit-lock.el instead.
+
+*** iso-acc.el is now obsolete. Use one of the latin input methods instead.
+
+*** zone-mode.el is now obsolete. Use dns-mode.el instead.
+
+*** cplus-md.el has been deleted.
+
+** Miscellaneous
+
+*** The variable `woman-topic-at-point' is renamed
+to `woman-use-topic-at-point' and behaves differently: if this
+variable is non-nil, the `woman' command uses the word at point
+automatically, without asking for a confirmation. Otherwise, the word
+at point is suggested as default, but not inserted at the prompt.
+
+*** You can now customize `fill-nobreak-predicate' to control where
+filling can break lines. The value is now normally a list of
+functions, but it can also be a single function, for compatibility.
+
+Emacs provide two predicates, `fill-single-word-nobreak-p' and
+`fill-french-nobreak-p', for use as the value of
+`fill-nobreak-predicate'.
+
+*** M-x view-file and commands that use it now avoid interfering
+with special modes such as Tar mode.
+
+*** `global-whitespace-mode' is a new alias for `whitespace-global-mode'.
+
+*** The saveplace.el package now filters out unreadable files.
+
+When you exit Emacs, the saved positions in visited files no longer
+include files that aren't readable, e.g. files that don't exist.
+Customize the new option `save-place-forget-unreadable-files' to nil
+to get the old behavior. The new options `save-place-save-skipped'
+and `save-place-skip-check-regexp' allow further fine-tuning of this
+feature.
+
+*** Commands `winner-redo' and `winner-undo', from winner.el, are now
+bound to C-c <left> and C-c <right>, respectively. This is an
+incompatible change.
+
+*** The type-break package now allows `type-break-file-name' to be nil
+and if so, doesn't store any data across sessions. This is handy if
+you don't want the `.type-break' file in your home directory or are
+annoyed by the need for interaction when you kill Emacs.
+
+*** `ps-print' can now print characters from the mule-unicode charsets.
+
+Printing text with characters from the mule-unicode-* sets works with
+`ps-print', provided that you have installed the appropriate BDF
+fonts. See the file INSTALL for URLs where you can find these fonts.
+
+*** New command `strokes-global-set-stroke-string'.
+This is like `strokes-global-set-stroke', but it allows you to bind
+the stroke directly to a string to insert. This is convenient for
+using strokes as an input method.
+
+*** In Outline mode, `hide-body' no longer hides lines at the top
+of the file that precede the first header line.
+
+*** `hide-ifdef-mode' now uses overlays rather than selective-display
+to hide its text. This should be mostly transparent but slightly
+changes the behavior of motion commands like C-e and C-p.
+
+*** In Artist mode the variable `artist-text-renderer' has been
+renamed to `artist-text-renderer-function'. The old name is still
+available as alias.
+
+*** In Enriched mode, `set-left-margin' and `set-right-margin' are now
+by default bound to `C-c [' and `C-c ]' instead of the former `C-c C-l'
+and `C-c C-r'.
+
+*** `partial-completion-mode' now handles partial completion on directory names.
+
+*** You can now disable pc-selection-mode after enabling it.
+
+M-x pc-selection-mode behaves like a proper minor mode, and with no
+argument it toggles the mode. Turning off PC-Selection mode restores
+the global key bindings that were replaced by turning on the mode.
+
+*** `uniquify-strip-common-suffix' tells uniquify to prefer
+`file|dir1' and `file|dir2' to `file|dir1/subdir' and `file|dir2/subdir'.
+
+*** New user option `add-log-always-start-new-record'.
+
+When this option is enabled, M-x add-change-log-entry always
+starts a new record regardless of when the last record is.
+
+*** M-x compare-windows now can automatically skip non-matching text to
+resync points in both windows.
+
+*** PO translation files are decoded according to their MIME headers
+when Emacs visits them.
+
+*** Telnet now prompts you for a port number with C-u M-x telnet.
+
+*** calculator.el now has radix grouping mode.
+
+To enable this, set `calculator-output-radix' non-nil. In this mode a
+separator character is used every few digits, making it easier to see
+byte boundaries etc. For more info, see the documentation of the
+variable `calculator-radix-grouping-mode'.
+
+*** LDAP support now defaults to ldapsearch from OpenLDAP version 2.
+
+*** The terminal emulation code in term.el has been improved; it can
+run most curses applications now.
+
+*** Support for `magic cookie' standout modes has been removed.
+
+Emacs still works on terminals that require magic cookies in order to
+use standout mode, but they can no longer display mode-lines in
+inverse-video.
+
+\f
+* Changes in Emacs 22.1 on non-free operating systems
+
+** The HOME directory defaults to Application Data under the user profile.
+
+If you used a previous version of Emacs without setting the HOME
+environment variable and a `.emacs' was saved, then Emacs will continue
+using C:/ as the default HOME. But if you are installing Emacs afresh,
+the default location will be the "Application Data" (or similar
+localized name) subdirectory of your user profile. A typical location
+of this directory is "C:\Documents and Settings\USERNAME\Application Data",
+where USERNAME is your user name.
+
+This change means that users can now have their own `.emacs' files on
+shared computers, and the default HOME directory is less likely to be
+read-only on computers that are administered by someone else.
+
+** Images are now supported on MS Windows.
+
+PBM and XBM images are supported out of the box. Other image formats
+depend on external libraries. All of these libraries have been ported
+to Windows, and can be found in both source and binary form at
+http://gnuwin32.sourceforge.net/. Note that libpng also depends on
+zlib, and tiff depends on the version of jpeg that it was compiled
+against. For additional information, see nt/INSTALL.
+
+** Sound is now supported on MS Windows.
+
+WAV format is supported on all versions of Windows, other formats such
+as AU, AIFF and MP3 may be supported in the more recent versions of
+Windows, or when other software provides hooks into the system level
+sound support for those formats.
+
+** Tooltips now work on MS Windows.
+
+See the Emacs 21.1 NEWS entry for tooltips for details.
+
+** Pointing devices with more than 3 buttons are now supported on MS Windows.
+
+The new variable `w32-pass-extra-mouse-buttons-to-system' controls
+whether Emacs should handle the extra buttons itself (the default), or
+pass them to Windows to be handled with system-wide functions.
+
+** Passing resources on the command line now works on MS Windows.
+
+You can use --xrm to pass resource settings to Emacs, overriding any
+existing values. For example:
+
+ emacs --xrm "Emacs.Background:red" --xrm "Emacs.Geometry:100x20"
+
+will start up Emacs on an initial frame of 100x20 with red background,
+irrespective of geometry or background setting on the Windows registry.
+
+** Emacs takes note of colors defined in Control Panel on MS-Windows.
+
+The Control Panel defines some default colors for applications in much
+the same way as wildcard X Resources do on X. Emacs now adds these
+colors to the colormap prefixed by System (eg SystemMenu for the
+default Menu background, SystemMenuText for the foreground), and uses
+some of them to initialize some of the default faces.
+`list-colors-display' shows the list of System color names, in case
+you wish to use them in other faces.
+
+** Running in a console window in Windows now uses the console size.
+
+Previous versions of Emacs erred on the side of having a usable Emacs
+through telnet, even though that was inconvenient if you use Emacs in
+a local console window with a scrollback buffer. The default value of
+w32-use-full-screen-buffer is now nil, which favors local console
+windows. Recent versions of Windows telnet also work well with this
+setting. If you are using an older telnet server then Emacs detects
+that the console window dimensions that are reported are not sane, and
+defaults to 80x25. If you use such a telnet server regularly at a size
+other than 80x25, you can still manually set
+w32-use-full-screen-buffer to t.
+
+** Different shaped mouse pointers are supported on MS Windows.
+
+The mouse pointer changes shape depending on what is under the pointer.
+
+** On MS Windows, the "system caret" now follows the cursor.
+
+This enables Emacs to work better with programs that need to track the
+cursor, for example screen magnifiers and text to speech programs.
+When such a program is in use, the system caret is made visible
+instead of Emacs drawing its own cursor. This seems to be required by
+some programs. The new variable w32-use-visible-system-caret allows
+the caret visibility to be manually toggled.
+
+** On MS Windows NT/W2K/XP, Emacs uses Unicode for clipboard operations.
+
+Those systems use Unicode internally, so this allows Emacs to share
+multilingual text with other applications. On other versions of
+MS Windows, Emacs now uses the appropriate locale coding-system, so
+the clipboard should work correctly for your local language without
+any customizations.
+
+** On Mac OS, `keyboard-coding-system' changes based on the keyboard script.
+
+** The variable `mac-keyboard-text-encoding' and the constants
+`kTextEncodingMacRoman', `kTextEncodingISOLatin1', and
+`kTextEncodingISOLatin2' are obsolete.
+
+** The variable `mac-command-key-is-meta' is obsolete. Use
+`mac-command-modifier' and `mac-option-modifier' instead.
+\f
+* Incompatible Lisp Changes in Emacs 22.1
+
+** Mode line display ignores text properties as well as the
+:propertize and :eval forms in the value of a variable whose
+`risky-local-variable' property is nil.
+
+The function `comint-send-input' now accepts 3 optional arguments:
+
+ (comint-send-input &optional no-newline artificial)
+
+Callers sending input not from the user should use bind the 3rd
+argument `artificial' to a non-nil value, to prevent Emacs from
+deleting the part of subprocess output that matches the input.
+
+** The `read-file-name' function now returns a null string if the
+user just types RET.
+
+** The variables post-command-idle-hook and post-command-idle-delay have
+been removed. Use run-with-idle-timer instead.
+
+** A hex or octal escape in a string constant forces the string to
+be multibyte or unibyte, respectively.
+
+** The explicit method of creating a display table element by
+combining a face number and a character code into a numeric
+glyph code is deprecated.
+
+Instead, the new functions `make-glyph-code', `glyph-char', and
+`glyph-face' must be used to create and decode glyph codes in
+display tables.
+
+** `suppress-keymap' now works by remapping `self-insert-command' to
+the command `undefined'. (In earlier Emacs versions, it used
+`substitute-key-definition' to rebind self inserting characters to
+`undefined'.)
+
+** The third argument of `accept-process-output' is now milliseconds.
+It used to be microseconds.
+
+** The function find-operation-coding-system may be called with a cons
+(FILENAME . BUFFER) in the second argument if the first argument
+OPERATION is `insert-file-contents', and thus a function registered in
+`file-coding-system-alist' is also called with such an argument.
+
+** When Emacs receives a USR1 or USR2 signal, this generates
+input events: sigusr1 or sigusr2. Use special-event-map to
+handle these events.
+
+** The variable `memory-full' now remains t until
+there is no longer a shortage of memory.
+
+** Support for Mocklisp has been removed.
+
+\f
+* Lisp Changes in Emacs 22.1
+
+** General Lisp changes:
+
+*** New syntax: \s now stands for the SPACE character.
+
+`?\s' is a new way to write the space character. You must make sure
+it is not followed by a dash, since `?\s-...' indicates the "super"
+modifier. However, it would be strange to write a character constant
+and a following symbol (beginning with `-') with no space between
+them.
+
+`\s' stands for space in strings, too, but it is not really meant for
+strings; it is easier and nicer just to write a space.
+
+*** New syntax: \uXXXX and \UXXXXXXXX specify Unicode code points in hex.
+
+For instance, you can use "\u0428" to specify a string consisting of
+CYRILLIC CAPITAL LETTER SHA, or `"U0001D6E2" to specify one consisting
+of MATHEMATICAL ITALIC CAPITAL ALPHA (the latter is greater than
+#xFFFF and thus needs the longer syntax).
+
+This syntax works for both character constants and strings.
+
+*** New function `unsafep' determines whether a Lisp form is safe.
+
+It returns nil if the given Lisp form can't possibly do anything
+dangerous; otherwise it returns a reason why the form might be unsafe
+(calls unknown function, alters global variable, etc.).
+
+*** The function `eql' is now available without requiring the CL package.
+
+*** The new function `memql' is like `memq', but uses `eql' for comparison,
+that is, floats are compared by value and other elements with `eq'.
+
+*** New functions `string-or-null-p' and `booleanp'.
+
++`string-or-null-p' returns non-nil if OBJECT is a string or nil.
++`booleanp' returns non-nil if OBJECT is t or nil.
+
+*** `makehash' is now obsolete. Use `make-hash-table' instead.
+
+*** Minor change in the function `format'.
+
+Some flags that were accepted but not implemented (such as "*") are no
+longer accepted.
+
+*** `add-to-list' takes an optional third argument, APPEND.
+
+If APPEND is non-nil, the new element gets added at the end of the
+list instead of at the beginning. This change actually occurred in
+Emacs 21.1, but was not documented then.
+
+*** New function `add-to-ordered-list' is like `add-to-list' but
+associates a numeric ordering of each element added to the list.
+
+*** New function `add-to-history' adds an element to a history list.
+
+Lisp packages should use this function to add elements to their
+history lists.
+
+If `history-delete-duplicates' is non-nil, it removes duplicates of
+the new element from the history list it updates.
+
+*** New function `copy-tree' makes a copy of a tree.
+
+It recursively copies through both CARs and CDRs.
+
+*** New function `delete-dups' deletes `equal' duplicate elements from a list.
+
+It modifies the list destructively, like `delete'. Of several `equal'
+occurrences of an element in the list, the one that's kept is the
+first one.
+
+*** New function `rassq-delete-all'.
+
+(rassq-delete-all VALUE ALIST) deletes, from ALIST, each element whose
+CDR is `eq' to the specified value.
+
+*** Functions `get' and `plist-get' no longer give errors for bad plists.
+
+They return nil for a malformed property list or if the list is
+cyclic.
+
+*** New functions `lax-plist-get' and `lax-plist-put'.
+
+They are like `plist-get' and `plist-put', except that they compare
+the property name using `equal' rather than `eq'.
+
+*** The function `number-sequence' makes a list of equally-separated numbers.
+
+For instance, (number-sequence 4 9) returns (4 5 6 7 8 9). By
+default, the separation is 1, but you can specify a different
+separation as the third argument. (number-sequence 1.5 6 2) returns
+(1.5 3.5 5.5).
+
+*** New variables `most-positive-fixnum' and `most-negative-fixnum'.
+
+They hold the largest and smallest possible integer values.
+
+*** The function `expt' handles negative exponents differently.
+The value for `(expt A B)', if both A and B are integers and B is
+negative, is now a float. For example: (expt 2 -2) => 0.25.
+
+*** The function `atan' now accepts an optional second argument.
+
+When called with 2 arguments, as in `(atan Y X)', `atan' returns the
+angle in radians between the vector [X, Y] and the X axis. (This is
+equivalent to the standard C library function `atan2'.)
+
+*** New macro `with-case-table'
+
+This executes the body with the case table temporarily set to a given
+case table.
+
+*** New macro `with-local-quit' temporarily allows quitting.
+
+A quit inside the body of `with-local-quit' is caught by the
+`with-local-quit' form itself, but another quit will happen later once
+the code that has inhibited quitting exits.
+
+This is for use around potentially blocking or long-running code
+inside timer functions and `post-command-hook' functions.
+
+*** New macro `define-obsolete-function-alias'.
+
+This combines `defalias' and `make-obsolete'.
+
+*** New macro `eval-at-startup' specifies expressions to
+evaluate when Emacs starts up. If this is done after startup,
+it evaluates those expressions immediately.
+
+This is useful in packages that can be preloaded.
+
+*** New function `macroexpand-all' expands all macros in a form.
+
+It is similar to the Common-Lisp function of the same name.
+One difference is that it guarantees to return the original argument
+if no expansion is done, which can be tested using `eq'.
+
+*** A function or macro's doc string can now specify the calling pattern.
+
+You put this info in the doc string's last line. It should be
+formatted so as to match the regexp "\n\n(fn .*)\\'". If you don't
+specify this explicitly, Emacs determines it from the actual argument
+names. Usually that default is right, but not always.
+
+*** New variable `print-continuous-numbering'.
+
+When this is non-nil, successive calls to print functions use a single
+numbering scheme for circular structure references. This is only
+relevant when `print-circle' is non-nil.
+
+When you bind `print-continuous-numbering' to t, you should
+also bind `print-number-table' to nil.
+
+*** `list-faces-display' takes an optional argument, REGEXP.
+
+If it is non-nil, the function lists only faces matching this regexp.
+
+*** New hook `command-error-function'.
+
+By setting this variable to a function, you can control
+how the editor command loop shows the user an error message.
+
+*** `debug-on-entry' accepts primitive functions that are not special forms.
+
+** Lisp code indentation features:
+
+*** The `defmacro' form can contain indentation and edebug declarations.
+
+These declarations specify how to indent the macro calls in Lisp mode
+and how to debug them with Edebug. You write them like this:
+
+ (defmacro NAME LAMBDA-LIST [DOC-STRING] [DECLARATION ...] ...)
+
+DECLARATION is a list `(declare DECLARATION-SPECIFIER ...)'. The
+possible declaration specifiers are:
+
+(indent INDENT)
+ Set NAME's `lisp-indent-function' property to INDENT.
+
+(edebug DEBUG)
+ Set NAME's `edebug-form-spec' property to DEBUG. (This is
+ equivalent to writing a `def-edebug-spec' for the macro,
+ but this is cleaner.)
+
+*** cl-indent now allows customization of Indentation of backquoted forms.
+
+See the new user option `lisp-backquote-indentation'.
+
+*** cl-indent now handles indentation of simple and extended `loop' forms.
+
+The new user options `lisp-loop-keyword-indentation',
+`lisp-loop-forms-indentation', and `lisp-simple-loop-indentation' can
+be used to customize the indentation of keywords and forms in loop
+forms.
+
+** Variable aliases:
+
+*** New function: defvaralias ALIAS-VAR BASE-VAR [DOCSTRING]
+
+This function defines the symbol ALIAS-VAR as a variable alias for
+symbol BASE-VAR. This means that retrieving the value of ALIAS-VAR
+returns the value of BASE-VAR, and changing the value of ALIAS-VAR
+changes the value of BASE-VAR.
+
+DOCSTRING, if present, is the documentation for ALIAS-VAR; else it has
+the same documentation as BASE-VAR.
+
+*** The macro `define-obsolete-variable-alias' combines `defvaralias' and
+`make-obsolete-variable'.
+
+*** New function: indirect-variable VARIABLE
+
+This function returns the variable at the end of the chain of aliases
+of VARIABLE. If VARIABLE is not a symbol, or if VARIABLE is not
+defined as an alias, the function returns VARIABLE.
+
+It might be noteworthy that variables aliases work for all kinds of
+variables, including buffer-local and frame-local variables.
+
+** defcustom changes:
+
+*** The package-version keyword has been added to provide
+`customize-changed-options' functionality to packages in the future.
+Developers who make use of this keyword must also update the new
+variable `customize-package-emacs-version-alist'.
+
+*** The new customization type `float' requires a floating point number.
+
+** String changes:
+
+*** A hex escape in a string constant forces the string to be multibyte.
+
+*** An octal escape in a string constant forces the string to be unibyte.
+
+*** New function `string-to-multibyte' converts a unibyte string to a
+multibyte string with the same individual character codes.
+
+*** `split-string' now includes null substrings in the returned list if
+the optional argument SEPARATORS is non-nil and there are matches for
+SEPARATORS at the beginning or end of the string. If SEPARATORS is
+nil, or if the new optional third argument OMIT-NULLS is non-nil, all
+empty matches are omitted from the returned list.
+
+*** The new function `assoc-string' replaces `assoc-ignore-case' and
+`assoc-ignore-representation', which are still available, but have
+been declared obsolete.
+
+*** New function `substring-no-properties' returns a substring without
+text properties.
+
+** Displaying warnings to the user.
+
+See the functions `warn' and `display-warning', or the Lisp Manual.
+If you want to be sure the warning will not be overlooked, this
+facility is much better than using `message', since it displays
+warnings in a separate window.
+
+** Progress reporters.
+
+These provide a simple and uniform way for commands to present
+progress messages for the user.
+
+See the new functions `make-progress-reporter',
+`progress-reporter-update', `progress-reporter-force-update',
+`progress-reporter-done', and `dotimes-with-progress-reporter'.
+
+** Buffer positions:
+
+*** Function `compute-motion' now calculates the usable window
+width if the WIDTH argument is nil. If the TOPOS argument is nil,
+the usable window height and width is used.
+
+*** The `line-move', `scroll-up', and `scroll-down' functions will now
+modify the window vscroll to scroll through display rows that are
+taller that the height of the window, for example in the presence of
+large images. To disable this feature, bind the new variable
+`auto-window-vscroll' to nil.
+
+*** The argument to `forward-word', `backward-word' is optional.
+
+It defaults to 1.
+
+*** Argument to `forward-to-indentation' and `backward-to-indentation' is optional.
+
+It defaults to 1.
+
+*** `field-beginning' and `field-end' take new optional argument, LIMIT.
+
+This argument tells them not to search beyond LIMIT. Instead they
+give up and return LIMIT.
+
+*** New function `window-line-height' is an efficient way to get
+information about a specific text line in a window provided that the
+window's display is up-to-date.
+
+*** New function `line-number-at-pos' returns the line number of a position.
+
+It an optional buffer position argument that defaults to point.
+
+*** Function `pos-visible-in-window-p' now returns the pixel coordinates
+and partial visibility state of the corresponding row, if the PARTIALLY
+arg is non-nil.
+
+*** New functions `posn-at-point' and `posn-at-x-y' return
+click-event-style position information for a given visible buffer
+position or for a given window pixel coordinate.
+
+*** New function `mouse-on-link-p' tests if a position is in a clickable link.
+
+This is the function used by the new `mouse-1-click-follows-link'
+functionality.
+
+** Text modification:
+
+*** The new function `buffer-chars-modified-tick' returns a buffer's
+tick counter for changes to characters. Each time text in that buffer
+is inserted or deleted, the character-change counter is updated to the
+tick counter (`buffer-modified-tick'). Text property changes leave it
+unchanged.
+
+*** The new function `insert-for-yank' normally works like `insert', but
+removes the text properties in the `yank-excluded-properties' list
+and handles the `yank-handler' text property.
+
+*** The new function `insert-buffer-substring-as-yank' is like
+`insert-for-yank' except that it gets the text from another buffer as
+in `insert-buffer-substring'.
+
+*** The new function `insert-buffer-substring-no-properties' is like
+`insert-buffer-substring', but removes all text properties from the
+inserted substring.
+
+*** The new function `filter-buffer-substring' extracts a buffer
+substring, passes it through a set of filter functions, and returns
+the filtered substring. Use it instead of `buffer-substring' or
+`delete-and-extract-region' when copying text into a user-accessible
+data structure, such as the kill-ring, X clipboard, or a register.
+
+The list of filter function is specified by the new variable
+`buffer-substring-filters'. For example, Longlines mode adds to
+`buffer-substring-filters' to remove soft newlines from the copied
+text.
+
+*** Function `translate-region' accepts also a char-table as TABLE
+argument.
+
+*** The new translation table `translation-table-for-input'
+is used for customizing self-insertion. The character to
+be inserted is translated through it.
+
+*** Text clones.
+
+The new function `text-clone-create'. Text clones are chunks of text
+that are kept identical by transparently propagating changes from one
+clone to the other.
+
+*** The function `insert-string' is now obsolete.
+
+** Filling changes.
+
+*** In determining an adaptive fill prefix, Emacs now tries the function in
+`adaptive-fill-function' _before_ matching the buffer line against
+`adaptive-fill-regexp' rather than _after_ it.
+
+** Atomic change groups.
+
+To perform some changes in the current buffer "atomically" so that
+they either all succeed or are all undone, use `atomic-change-group'
+around the code that makes changes. For instance:
+
+ (atomic-change-group
+ (insert foo)
+ (delete-region x y))
+
+If an error (or other nonlocal exit) occurs inside the body of
+`atomic-change-group', it unmakes all the changes in that buffer that
+were during the execution of the body. The change group has no effect
+on any other buffers--any such changes remain.
+
+If you need something more sophisticated, you can directly call the
+lower-level functions that `atomic-change-group' uses. Here is how.
+
+To set up a change group for one buffer, call `prepare-change-group'.
+Specify the buffer as argument; it defaults to the current buffer.
+This function returns a "handle" for the change group. You must save
+the handle to activate the change group and then finish it.
+
+Before you change the buffer again, you must activate the change
+group. Pass the handle to `activate-change-group' afterward to
+do this.
+
+After you make the changes, you must finish the change group. You can
+either accept the changes or cancel them all. Call
+`accept-change-group' to accept the changes in the group as final;
+call `cancel-change-group' to undo them all.
+
+You should use `unwind-protect' to make sure the group is always
+finished. The call to `activate-change-group' should be inside the
+`unwind-protect', in case the user types C-g just after it runs.
+(This is one reason why `prepare-change-group' and
+`activate-change-group' are separate functions.) Once you finish the
+group, don't use the handle again--don't try to finish the same group
+twice.
+
+To make a multibuffer change group, call `prepare-change-group' once
+for each buffer you want to cover, then use `nconc' to combine the
+returned values, like this:
+
+ (nconc (prepare-change-group buffer-1)
+ (prepare-change-group buffer-2))
+
+You can then activate the multibuffer change group with a single call
+to `activate-change-group', and finish it with a single call to
+`accept-change-group' or `cancel-change-group'.
+
+Nested use of several change groups for the same buffer works as you
+would expect. Non-nested use of change groups for the same buffer
+will lead to undesirable results, so don't let it happen; the first
+change group you start for any given buffer should be the last one
+finished.
+
+** Buffer-related changes:
+
+*** The new function `buffer-local-value' returns the buffer-local
+binding of VARIABLE (a symbol) in buffer BUFFER. If VARIABLE does not
+have a buffer-local binding in buffer BUFFER, it returns the default
+value of VARIABLE instead.
+
+*** `list-buffers-noselect' now takes an additional argument, BUFFER-LIST.
+
+If it is non-nil, it specifies which buffers to list.
+
+*** `kill-buffer-hook' is now a permanent local.
+
+*** The function `frame-or-buffer-changed-p' now lets you maintain
+various status records in parallel.
+
+It takes a variable (a symbol) as argument. If the variable is non-nil,
+then its value should be a vector installed previously by
+`frame-or-buffer-changed-p'. If the frame names, buffer names, buffer
+order, or their read-only or modified flags have changed, since the
+time the vector's contents were recorded by a previous call to
+`frame-or-buffer-changed-p', then the function returns t. Otherwise
+it returns nil.
+
+On the first call to `frame-or-buffer-changed-p', the variable's
+value should be nil. `frame-or-buffer-changed-p' stores a suitable
+vector into the variable and returns t.
+
+If the variable is itself nil, then `frame-or-buffer-changed-p' uses,
+for compatibility, an internal variable which exists only for this
+purpose.
+
+*** The function `read-buffer' follows the convention for reading from
+the minibuffer with a default value: if DEF is non-nil, the minibuffer
+prompt provided in PROMPT is edited to show the default value provided
+in DEF before the terminal colon and space.
+
+** Searching and matching changes:
+
+*** New function `looking-back' checks whether a regular expression matches
+the text before point. Specifying the LIMIT argument bounds how far
+back the match can start; this is a way to keep it from taking too long.
+
+*** The new variable `search-spaces-regexp' controls how to search
+for spaces in a regular expression. If it is non-nil, it should be a
+regular expression, and any series of spaces stands for that regular
+expression. If it is nil, spaces stand for themselves.
+
+Spaces inside of constructs such as `[..]' and inside loops such as
+`*', `+', and `?' are never replaced with `search-spaces-regexp'.
+
+*** New regular expression operators, `\_<' and `\_>'.
+
+These match the beginning and end of a symbol. A symbol is a
+non-empty sequence of either word or symbol constituent characters, as
+specified by the syntax table.
+
+*** `skip-chars-forward' and `skip-chars-backward' now handle
+character classes such as `[:alpha:]', along with individual
+characters and ranges.
+
+*** In `replace-match', the replacement text no longer inherits
+properties from surrounding text.
+
+*** The list returned by `(match-data t)' now has the buffer as a final
+element, if the last match was on a buffer. `set-match-data'
+accepts such a list for restoring the match state.
+
+*** Functions `match-data' and `set-match-data' now have an optional
+argument `reseat'. When non-nil, all markers in the match data list
+passed to these functions will be reseated to point to nowhere.
+
+*** rx.el has new corresponding `symbol-start' and `symbol-end' elements.
+
+*** The default value of `sentence-end' is now defined using the new
+variable `sentence-end-without-space', which contains such characters
+that end a sentence without following spaces.
+
+The function `sentence-end' should be used to obtain the value of the
+variable `sentence-end'. If the variable `sentence-end' is nil, then
+this function returns the regexp constructed from the variables
+`sentence-end-without-period', `sentence-end-double-space' and
+`sentence-end-without-space'.
+
+** Undo changes:
+
+*** `buffer-undo-list' allows programmable elements.
+
+These elements have the form (apply FUNNAME . ARGS), where FUNNAME is
+a symbol other than t or nil. That stands for a high-level change
+that should be undone by evaluating (apply FUNNAME ARGS).
+
+These entries can also have the form (apply DELTA BEG END FUNNAME . ARGS)
+which indicates that the change which took place was limited to the
+range BEG...END and increased the buffer size by DELTA.
+
+*** If the buffer's undo list for the current command gets longer than
+`undo-outer-limit', garbage collection empties it. This is to prevent
+it from using up the available memory and choking Emacs.
+
+** Killing and yanking changes:
+
+*** New `yank-handler' text property can be used to control how
+previously killed text on the kill ring is reinserted.
+
+The value of the `yank-handler' property must be a list with one to four
+elements with the following format:
+ (FUNCTION PARAM NOEXCLUDE UNDO).
+
+The `insert-for-yank' function looks for a yank-handler property on
+the first character on its string argument (typically the first
+element on the kill-ring). If a `yank-handler' property is found,
+the normal behavior of `insert-for-yank' is modified in various ways:
+
+ When FUNCTION is present and non-nil, it is called instead of `insert'
+to insert the string. FUNCTION takes one argument--the object to insert.
+ If PARAM is present and non-nil, it replaces STRING as the object
+passed to FUNCTION (or `insert'); for example, if FUNCTION is
+`yank-rectangle', PARAM should be a list of strings to insert as a
+rectangle.
+ If NOEXCLUDE is present and non-nil, the normal removal of the
+`yank-excluded-properties' is not performed; instead FUNCTION is
+responsible for removing those properties. This may be necessary
+if FUNCTION adjusts point before or after inserting the object.
+ If UNDO is present and non-nil, it is a function that will be called
+by `yank-pop' to undo the insertion of the current object. It is
+called with two arguments, the start and end of the current region.
+FUNCTION can set `yank-undo-function' to override the UNDO value.
+
+*** The functions `kill-new', `kill-append', and `kill-region' now have an
+optional argument to specify the `yank-handler' text property to put on
+the killed text.
+
+*** The function `yank-pop' will now use a non-nil value of the variable
+`yank-undo-function' (instead of `delete-region') to undo the previous
+`yank' or `yank-pop' command (or a call to `insert-for-yank'). The function
+`insert-for-yank' automatically sets that variable according to the UNDO
+element of the string argument's `yank-handler' text property if present.
+
+*** The function `insert-for-yank' now supports strings where the
+`yank-handler' property does not span the first character of the
+string. The old behavior is available if you call
+`insert-for-yank-1' instead.
+
+** Syntax table changes:
+
+*** The new function `syntax-ppss' provides an efficient way to find the
+current syntactic context at point.
+
+*** The new function `syntax-after' returns the syntax code
+of the character after a specified buffer position, taking account
+of text properties as well as the character code.
+
+*** `syntax-class' extracts the class of a syntax code (as returned
+by `syntax-after').
+
+*** The macro `with-syntax-table' no longer copies the syntax table.
+
+** File operation changes:
+
+*** New vars `exec-suffixes' and `load-suffixes' used when
+searching for an executable or an Emacs Lisp file.
+
+*** New function `locate-file' searches for a file in a list of directories.
+`locate-file' accepts a name of a file to search (a string), and two
+lists: a list of directories to search in and a list of suffixes to
+try; typical usage might use `exec-path' and `load-path' for the list
+of directories, and `exec-suffixes' and `load-suffixes' for the list
+of suffixes. The function also accepts a predicate argument to
+further filter candidate files.
+
+One advantage of using this function is that the list of suffixes in
+`exec-suffixes' is OS-dependant, so this function will find
+executables without polluting Lisp code with OS dependencies.
+
+*** The new function `file-remote-p' tests a file name and returns
+non-nil if it specifies a remote file (one that Emacs accesses using
+its own special methods and not directly through the file system).
+The value in that case is an identifier for the remote file system.
+
+*** The new hook `before-save-hook' is invoked by `basic-save-buffer'
+before saving buffers. This allows packages to perform various final
+tasks. For example, it can be used by the copyright package to make
+sure saved files have the current year in any copyright headers.
+
+*** `file-chase-links' now takes an optional second argument LIMIT which
+specifies the maximum number of links to chase through. If after that
+many iterations the file name obtained is still a symbolic link,
+`file-chase-links' returns it anyway.
+
+*** Functions `file-name-sans-extension' and `file-name-extension' now
+ignore the leading dots in file names, so that file names such as
+`.emacs' are treated as extensionless.
+
+*** If `buffer-save-without-query' is non-nil in some buffer,
+`save-some-buffers' will always save that buffer without asking (if
+it's modified).
+
+*** `buffer-auto-save-file-format' is the new name for what was
+formerly called `auto-save-file-format'. It is now a permanent local.
+
+*** `visited-file-modtime' and `calendar-time-from-absolute' now return
+a list of two integers, instead of a cons.
+
+*** The precedence of file name handlers has been changed.
+
+Instead of choosing the first handler that matches,
+`find-file-name-handler' now gives precedence to a file name handler
+that matches nearest the end of the file name. More precisely, the
+handler whose (match-beginning 0) is the largest is chosen. In case
+of ties, the old "first matched" rule applies.
+
+*** A file name handler can declare which operations it handles.
+
+You do this by putting an `operation' property on the handler name
+symbol. The property value should be a list of the operations that
+the handler really handles. It won't be called for any other
+operations.
+
+This is useful for autoloaded handlers, to prevent them from being
+autoloaded when not really necessary.
+
+*** The function `make-auto-save-file-name' is now handled by file
+name handlers. This will be exploited for remote files mainly.
+
+*** The function `file-name-completion' accepts an optional argument
+PREDICATE, and rejects completion candidates that don't satisfy PREDICATE.
+
+*** The new primitive `set-file-times' sets a file's access and
+modification times. Magic file name handlers can handle this
+operation.
+
+** Input changes:
+
+*** Functions `y-or-n-p', `read-char', `read-key-sequence' and the like, that
+display a prompt but don't use the minibuffer, now display the prompt
+using the text properties (esp. the face) of the prompt string.
+
+*** The functions `read-event', `read-char', and `read-char-exclusive'
+have a new optional argument SECONDS. If non-nil, this specifies a
+maximum time to wait for input, in seconds. If no input arrives after
+this time elapses, the functions stop waiting and return nil.
+
+*** An interactive specification can now use the code letter `U' to get
+the up-event that was discarded in case the last key sequence read for a
+previous `k' or `K' argument was a down-event; otherwise nil is used.
+
+*** The new interactive-specification `G' reads a file name
+much like `F', but if the input is a directory name (even defaulted),
+it returns just the directory name.
+
+*** (while-no-input BODY...) runs BODY, but only so long as no input
+arrives. If the user types or clicks anything, BODY stops as if a
+quit had occurred. `while-no-input' returns the value of BODY, if BODY
+finishes. It returns nil if BODY was aborted by a quit, and t if
+BODY was aborted by arrival of input.
+
+*** `recent-keys' now returns the last 300 keys.
+
+** Minibuffer changes:
+
+*** The new function `minibufferp' returns non-nil if its optional
+buffer argument is a minibuffer. If the argument is omitted, it
+defaults to the current buffer.
+
+*** New function `minibuffer-selected-window' returns the window which
+was selected when entering the minibuffer.
+
+*** The `read-file-name' function now takes an additional argument which
+specifies a predicate which the file name read must satisfy. The
+new variable `read-file-name-predicate' contains the predicate argument
+while reading the file name from the minibuffer; the predicate in this
+variable is used by read-file-name-internal to filter the completion list.
+
+*** The new variable `read-file-name-function' can be used by Lisp code
+to override the built-in `read-file-name' function.
+
+*** The new variable `read-file-name-completion-ignore-case' specifies
+whether completion ignores case when reading a file name with the
+`read-file-name' function.
+
+*** The new function `read-directory-name' is for reading a directory name.
+
+It is like `read-file-name' except that the defaulting works better
+for directories, and completion inside it shows only directories.
+
+*** The new variable `history-add-new-input' specifies whether to add new
+elements in history. If set to nil, minibuffer reading functions don't
+add new elements to the history list, so it is possible to do this
+afterwards by calling `add-to-history' explicitly.
+
+** Completion changes:
+
+*** The new function `minibuffer-completion-contents' returns the contents
+of the minibuffer just before point. That is what completion commands
+operate on.
+
+*** The functions `all-completions' and `try-completion' now accept lists
+of strings as well as hash-tables additionally to alists, obarrays
+and functions. Furthermore, the function `test-completion' is now
+exported to Lisp. The keys in alists and hash tables can be either
+strings or symbols, which are automatically converted with to strings.
+
+*** The new macro `dynamic-completion-table' supports using functions
+as a dynamic completion table.
+
+ (dynamic-completion-table FUN)
+
+FUN is called with one argument, the string for which completion is required,
+and it should return an alist containing all the intended possible
+completions. This alist can be a full list of possible completions so that FUN
+can ignore the value of its argument. If completion is performed in the
+minibuffer, FUN will be called in the buffer from which the minibuffer was
+entered. `dynamic-completion-table' then computes the completion.
+
+*** The new macro `lazy-completion-table' initializes a variable
+as a lazy completion table.
+
+ (lazy-completion-table VAR FUN)
+
+If the completion table VAR is used for the first time (e.g., by passing VAR
+as an argument to `try-completion'), the function FUN is called with no
+arguments. FUN must return the completion table that will be stored in VAR.
+If completion is requested in the minibuffer, FUN will be called in the buffer
+from which the minibuffer was entered. The return value of
+`lazy-completion-table' must be used to initialize the value of VAR.
+
+** Abbrev changes:
+
+*** `define-abbrev' now accepts an optional argument SYSTEM-FLAG.
+
+If non-nil, this marks the abbrev as a "system" abbrev, which means
+that it won't be stored in the user's abbrevs file if he saves the
+abbrevs. Major modes that predefine some abbrevs should always
+specify this flag.
+
+*** The new function `copy-abbrev-table' copies an abbrev table.
+
+It returns a new abbrev table that is a copy of a given abbrev table.
+
+** Enhancements to keymaps.
+
+*** Cleaner way to enter key sequences.
+
+You can enter a constant key sequence in a more natural format, the
+same one used for saving keyboard macros, using the macro `kbd'. For
+example,
+
+(kbd "C-x C-f") => "\^x\^f"
+
+Actually, this format has existed since Emacs 20.1.
+
+*** Interactive commands can be remapped through keymaps.
+
+This is an alternative to using `defadvice' or `substitute-key-definition'
+to modify the behavior of a key binding using the normal keymap
+binding and lookup functionality.
+
+When a key sequence is bound to a command, and that command is
+remapped to another command, that command is run instead of the
+original command.
+
+Example:
+Suppose that minor mode `my-mode' has defined the commands
+`my-kill-line' and `my-kill-word', and it wants C-k (and any other key
+bound to `kill-line') to run the command `my-kill-line' instead of
+`kill-line', and likewise it wants to run `my-kill-word' instead of
+`kill-word'.
+
+Instead of rebinding C-k and the other keys in the minor mode map,
+command remapping allows you to directly map `kill-line' into
+`my-kill-line' and `kill-word' into `my-kill-word' using `define-key':
+
+ (define-key my-mode-map [remap kill-line] 'my-kill-line)
+ (define-key my-mode-map [remap kill-word] 'my-kill-word)
+
+When `my-mode' is enabled, its minor mode keymap is enabled too. So
+when the user types C-k, that runs the command `my-kill-line'.
+
+Only one level of remapping is supported. In the above example, this
+means that if `my-kill-line' is remapped to `other-kill', then C-k still
+runs `my-kill-line'.
+
+The following changes have been made to provide command remapping:
+
+- Command remappings are defined using `define-key' with a prefix-key
+ `remap', i.e. `(define-key MAP [remap CMD] DEF)' remaps command CMD
+ to definition DEF in keymap MAP. The definition is not limited to
+ another command; it can be anything accepted for a normal binding.
+
+- The new function `command-remapping' returns the binding for a
+ remapped command in the current keymaps, or nil if not remapped.
+
+- `key-binding' now remaps interactive commands unless the optional
+ third argument NO-REMAP is non-nil.
+
+- `where-is-internal' now returns nil for a remapped command (e.g.
+ `kill-line', when `my-mode' is enabled), and the actual key binding for
+ the command it is remapped to (e.g. C-k for my-kill-line).
+ It also has a new optional fifth argument, NO-REMAP, which inhibits
+ remapping if non-nil (e.g. it returns "C-k" for `kill-line', and
+ "<kill-line>" for `my-kill-line').
+
+- The new variable `this-original-command' contains the original
+ command before remapping. It is equal to `this-command' when the
+ command was not remapped.
+
+*** The definition of a key-binding passed to define-key can use XEmacs-style
+key-sequences, such as [(control a)].
+
+*** New keymaps for typing file names
+
+Two new keymaps, `minibuffer-local-filename-completion-map' and
+`minibuffer-local-must-match-filename-map', apply whenever
+Emacs reads a file name in the minibuffer. These key maps override
+the usual binding of SPC to `minibuffer-complete-word' (so that file
+names with embedded spaces could be typed without the need to quote
+the spaces).
+
+*** New function `current-active-maps' returns a list of currently
+active keymaps.
+
+*** New function `describe-buffer-bindings' inserts the list of all
+defined keys and their definitions.
+
+*** New function `keymap-prompt' returns the prompt string of a keymap.
+
+*** If text has a `keymap' property, that keymap takes precedence
+over minor mode keymaps.
+
+*** The `keymap' property now also works at the ends of overlays and
+text properties, according to their stickiness. This also means that it
+works with empty overlays. The same hold for the `local-map' property.
+
+*** `key-binding' will now look up mouse-specific bindings. The
+keymaps consulted by `key-binding' will get adapted if the key
+sequence is started with a mouse event. Instead of letting the click
+position be determined from the key sequence itself, it is also
+possible to specify it with an optional argument explicitly.
+
+*** `define-key-after' now accepts keys longer than 1.
+
+*** (map-keymap FUNCTION KEYMAP) applies the function to each binding
+in the keymap.
+
+*** New variable `emulation-mode-map-alists'.
+
+Lisp packages using many minor mode keymaps can now maintain their own
+keymap alist separate from `minor-mode-map-alist' by adding their
+keymap alist to this list.
+
+*** Dense keymaps now handle inheritance correctly.
+
+Previously a dense keymap would hide all of the simple-char key
+bindings of the parent keymap.
+
+** Enhancements to process support
+
+*** Adaptive read buffering of subprocess output.
+
+On some systems, when Emacs reads the output from a subprocess, the
+output data is read in very small blocks, potentially resulting in
+very poor performance. This behavior can be remedied to some extent
+by setting the new variable `process-adaptive-read-buffering' to a
+non-nil value (the default), as it will automatically delay reading
+from such processes, allowing them to produce more output before
+Emacs tries to read it.
+
+*** Processes now have an associated property list where programs can
+maintain process state and other per-process related information.
+
+Use the new functions `process-get' and `process-put' to access, add,
+and modify elements on this property list. Use the new functions
+`process-plist' and `set-process-plist' to access and replace the
+entire property list of a process.
+
+*** Function `list-processes' now has an optional argument; if non-nil,
+it lists only the processes whose query-on-exit flag is set.
+
+*** New fns `set-process-query-on-exit-flag' and `process-query-on-exit-flag'.
+
+These replace the old function `process-kill-without-query'. That
+function is still supported, but new code should use the new
+functions.
+
+*** The new function `call-process-shell-command'.
+
+This executes a shell command synchronously in a separate process.
+
+*** The new function `process-file' is similar to `call-process', but
+obeys file handlers. The file handler is chosen based on
+`default-directory'.
+
+*** Function `signal-process' now accepts a process object or process
+name in addition to a process id to identify the signaled process.
+
+*** Function `accept-process-output' has a new optional fourth arg
+JUST-THIS-ONE. If non-nil, only output from the specified process
+is handled, suspending output from other processes. If value is an
+integer, also inhibit running timers. This feature is generally not
+recommended, but may be necessary for specific applications, such as
+speech synthesis.
+
+*** A process filter function gets the output as multibyte string
+if the process specifies t for its filter's multibyteness.
+
+That multibyteness is decided by the value of
+`default-enable-multibyte-characters' when the process is created, and
+you can change it later with `set-process-filter-multibyte'.
+
+*** The new function `set-process-filter-multibyte' sets the
+multibyteness of the strings passed to the process's filter.
+
+*** The new function `process-filter-multibyte-p' returns the
+multibyteness of the strings passed to the process's filter.
+
+*** If a process's coding system is `raw-text' or `no-conversion' and its
+buffer is multibyte, the output of the process is at first converted
+to multibyte by `string-to-multibyte' then inserted in the buffer.
+Previously, it was converted to multibyte by `string-as-multibyte',
+which was not compatible with the behavior of file reading.
+
+** Enhanced networking support.
+
+*** The new `make-network-process' function makes network connections.
+It allows opening of stream and datagram connections to a server, as well as
+create a stream or datagram server inside Emacs.
+
+- A server is started using :server t arg.
+- Datagram connection is selected using :type 'datagram arg.
+- A server can open on a random port using :service t arg.
+- Local sockets are supported using :family 'local arg.
+- IPv6 is supported (when available). You may explicitly select IPv6
+ using :family 'ipv6 arg.
+- Non-blocking connect is supported using :nowait t arg.
+- The process' property list can be initialized using :plist PLIST arg;
+ a copy of the server process' property list is automatically inherited
+ by new client processes created to handle incoming connections.
+
+To test for the availability of a given feature, use featurep like this:
+ (featurep 'make-network-process '(:type datagram))
+ (featurep 'make-network-process '(:family ipv6))
+
+*** The old `open-network-stream' now uses `make-network-process'.
+
+*** `process-contact' has an optional KEY argument.
+
+Depending on this argument, you can get the complete list of network
+process properties or a specific property. Using :local or :remote as
+the KEY, you get the address of the local or remote end-point.
+
+An Inet address is represented as a 5 element vector, where the first
+4 elements contain the IP address and the fifth is the port number.
+
+*** New functions `stop-process' and `continue-process'.
+
+These functions stop and restart communication through a network
+connection. For a server process, no connections are accepted in the
+stopped state. For a client process, no input is received in the
+stopped state.
+
+*** New function `format-network-address'.
+
+This function reformats the Lisp representation of a network address
+to a printable string. For example, an IP address A.B.C.D and port
+number P is represented as a five element vector [A B C D P], and the
+printable string returned for this vector is "A.B.C.D:P". See the doc
+string for other formatting options.
+
+*** New function `network-interface-list'.
+
+This function returns a list of network interface names and their
+current network addresses.
+
+*** New function `network-interface-info'.
+
+This function returns the network address, hardware address, current
+status, and other information about a specific network interface.
+
+*** New functions `process-datagram-address', `set-process-datagram-address'.
+
+These functions are used with datagram-based network processes to get
+and set the current address of the remote partner.
+
+*** Deleting a network process with `delete-process' calls the sentinel.
+
+The status message passed to the sentinel for a deleted network
+process is "deleted". The message passed to the sentinel when the
+connection is closed by the remote peer has been changed to
+"connection broken by remote peer".
+
+** Using window objects:
+
+*** You can now make a window as short as one line.
+
+A window that is just one line tall does not display either a mode
+line or a header line, even if the variables `mode-line-format' and
+`header-line-format' call for them. A window that is two lines tall
+cannot display both a mode line and a header line at once; if the
+variables call for both, only the mode line actually appears.
+
+*** The new function `window-inside-edges' returns the edges of the
+actual text portion of the window, not including the scroll bar or
+divider line, the fringes, the display margins, the header line and
+the mode line.
+
+*** The new functions `window-pixel-edges' and `window-inside-pixel-edges'
+return window edges in units of pixels, rather than columns and lines.
+
+*** New function `window-body-height'.
+
+This is like `window-height' but does not count the mode line or the
+header line.
+
+*** The new function `adjust-window-trailing-edge' moves the right
+or bottom edge of a window. It does not move other window edges.
+
+*** The new macro `with-selected-window' temporarily switches the
+selected window without impacting the order of `buffer-list'.
+It saves and restores the current buffer, too.
+
+*** `select-window' takes an optional second argument NORECORD.
+
+This is like `switch-to-buffer'.
+
+*** `save-selected-window' now saves and restores the selected window
+of every frame. This way, it restores everything that can be changed
+by calling `select-window'. It also saves and restores the current
+buffer.
+
+*** `set-window-buffer' has an optional argument KEEP-MARGINS.
+
+If non-nil, that says to preserve the window's current margin, fringe,
+and scroll-bar settings.
+
+*** The new function `window-tree' returns a frame's window tree.
+
+*** The functions `get-lru-window' and `get-largest-window' take an optional
+argument `dedicated'. If non-nil, those functions do not ignore
+dedicated windows.
+
+** Customizable fringe bitmaps
+
+*** There are new display properties, `left-fringe' and `right-fringe',
+that can be used to show a specific bitmap in the left or right fringe
+bitmap of the display line.
+
+Format is `display (left-fringe BITMAP [FACE])', where BITMAP is a
+symbol identifying a fringe bitmap, either built-in or defined with
+`define-fringe-bitmap', and FACE is an optional face name to be used
+for displaying the bitmap instead of the default `fringe' face.
+When specified, FACE is automatically merged with the `fringe' face.
+
+*** New buffer-local variables `fringe-indicator-alist' and
+`fringe-cursor-alist' maps between logical (internal) fringe indicator
+and cursor symbols and the actual fringe bitmaps to be displayed.
+This decouples the logical meaning of the fringe indicators from the
+physical appearance, as well as allowing different fringe bitmaps to
+be used in different windows showing different buffers.
+
+*** New function `define-fringe-bitmap' can now be used to create new
+fringe bitmaps, as well as change the built-in fringe bitmaps.
+
+*** New function `destroy-fringe-bitmap' deletes a fringe bitmap
+or restores a built-in one to its default value.
+
+*** New function `set-fringe-bitmap-face' specifies the face to be
+used for a specific fringe bitmap. The face is automatically merged
+with the `fringe' face, so normally, the face should only specify the
+foreground color of the bitmap.
+
+*** New function `fringe-bitmaps-at-pos' returns the current fringe
+bitmaps in the display line at a given buffer position.
+
+** Other window fringe features:
+
+*** Controlling the default left and right fringe widths.
+
+The default left and right fringe widths for all windows of a frame
+can now be controlled by setting the `left-fringe' and `right-fringe'
+frame parameters to an integer value specifying the width in pixels.
+Setting the width to 0 effectively removes the corresponding fringe.
+
+The actual default fringe widths for the frame may deviate from the
+specified widths, since the combined fringe widths must match an
+integral number of columns. The extra width is distributed evenly
+between the left and right fringe. To force a specific fringe width,
+specify the width as a negative integer (if both widths are negative,
+only the left fringe gets the specified width).
+
+Setting the width to nil (the default), restores the default fringe
+width which is the minimum number of pixels necessary to display any
+of the currently defined fringe bitmaps. The width of the built-in
+fringe bitmaps is 8 pixels.
+
+*** Per-window fringe and scrollbar settings
+
+**** Windows can now have their own individual fringe widths and
+position settings.
+
+To control the fringe widths of a window, either set the buffer-local
+variables `left-fringe-width', `right-fringe-width', or call
+`set-window-fringes'.
+
+To control the fringe position in a window, that is, whether fringes
+are positioned between the display margins and the window's text area,
+or at the edges of the window, either set the buffer-local variable
+`fringes-outside-margins' or call `set-window-fringes'.
+
+The function `window-fringes' can be used to obtain the current
+settings. To make `left-fringe-width', `right-fringe-width', and
+`fringes-outside-margins' take effect, you must set them before
+displaying the buffer in a window, or use `set-window-buffer' to force
+an update of the display margins.
+
+**** Windows can now have their own individual scroll-bar settings
+controlling the width and position of scroll-bars.
+
+To control the scroll-bar of a window, either set the buffer-local
+variables `scroll-bar-mode' and `scroll-bar-width', or call
+`set-window-scroll-bars'. The function `window-scroll-bars' can be
+used to obtain the current settings. To make `scroll-bar-mode' and
+`scroll-bar-width' take effect, you must set them before displaying
+the buffer in a window, or use `set-window-buffer' to force an update
+of the display margins.
+
+** Redisplay features:
+
+*** `sit-for' can now be called with args (SECONDS &optional NODISP).
+
+*** Iconifying or deiconifying a frame no longer makes sit-for return.
+
+*** New function `redisplay' causes an immediate redisplay if no input is
+available, equivalent to (sit-for 0). The call (redisplay t) forces
+an immediate redisplay even if input is pending.
+
+*** New function `force-window-update' can initiate a full redisplay of
+one or all windows. Normally, this is not needed as changes in window
+contents are detected automatically. However, certain implicit
+changes to mode lines, header lines, or display properties may require
+forcing an explicit window update.
+
+*** (char-displayable-p CHAR) returns non-nil if Emacs ought to be able
+to display CHAR. More precisely, if the selected frame's fontset has
+a font to display the character set that CHAR belongs to.
+
+Fontsets can specify a font on a per-character basis; when the fontset
+does that, this value cannot be accurate.
+
+*** You can define multiple overlay arrows via the new
+variable `overlay-arrow-variable-list'.
+
+It contains a list of variables which contain overlay arrow position
+markers, including the original `overlay-arrow-position' variable.
+
+Each variable on this list can have individual `overlay-arrow-string'
+and `overlay-arrow-bitmap' properties that specify an overlay arrow
+string (for non-window terminals) or fringe bitmap (for window
+systems) to display at the corresponding overlay arrow position.
+If either property is not set, the default `overlay-arrow-string' or
+'overlay-arrow-fringe-bitmap' will be used.
+
+*** New `line-height' and `line-spacing' properties for newline characters
+
+A newline can now have `line-height' and `line-spacing' text or overlay
+properties that control the height of the corresponding display row.
+
+If the `line-height' property value is t, the newline does not
+contribute to the height of the display row; instead the height of the
+newline glyph is reduced. Also, a `line-spacing' property on this
+newline is ignored. This can be used to tile small images or image
+slices without adding blank areas between the images.
+
+If the `line-height' property value is a positive integer, the value
+specifies the minimum line height in pixels. If necessary, the line
+height it increased by increasing the line's ascent.
+
+If the `line-height' property value is a float, the minimum line
+height is calculated by multiplying the default frame line height by
+the given value.
+
+If the `line-height' property value is a cons (FACE . RATIO), the
+minimum line height is calculated as RATIO * height of named FACE.
+RATIO is int or float. If FACE is t, it specifies the current face.
+
+If the `line-height' property value is a cons (nil . RATIO), the line
+height is calculated as RATIO * actual height of the line's contents.
+
+If the `line-height' value is a cons (HEIGHT . TOTAL), HEIGHT specifies
+the line height as described above, while TOTAL is any of the forms
+described above and specifies the total height of the line, causing a
+varying number of pixels to be inserted after the line to make it line
+exactly that many pixels high.
+
+If the `line-spacing' property value is an positive integer, the value
+is used as additional pixels to insert after the display line; this
+overrides the default frame `line-spacing' and any buffer local value of
+the `line-spacing' variable.
+
+If the `line-spacing' property is a float or cons, the line spacing
+is calculated as specified above for the `line-height' property.
+
+*** The buffer local `line-spacing' variable can now have a float value,
+which is used as a height relative to the default frame line height.
+
+*** Enhancements to stretch display properties
+
+The display property stretch specification form `(space PROPS)', where
+PROPS is a property list, now allows pixel based width and height
+specifications, as well as enhanced horizontal text alignment.
+
+The value of these properties can now be a (primitive) expression
+which is evaluated during redisplay. The following expressions
+are supported:
+
+EXPR ::= NUM | (NUM) | UNIT | ELEM | POS | IMAGE | FORM
+NUM ::= INTEGER | FLOAT | SYMBOL
+UNIT ::= in | mm | cm | width | height
+ELEM ::= left-fringe | right-fringe | left-margin | right-margin
+ | scroll-bar | text
+POS ::= left | center | right
+FORM ::= (NUM . EXPR) | (OP EXPR ...)
+OP ::= + | -
+
+The form `NUM' specifies a fractional width or height of the default
+frame font size. The form `(NUM)' specifies an absolute number of
+pixels. If a symbol is specified, its buffer-local variable binding
+is used. The `in', `mm', and `cm' units specifies the number of
+pixels per inch, milli-meter, and centi-meter, resp. The `width' and
+`height' units correspond to the width and height of the current face
+font. An image specification corresponds to the width or height of
+the image.
+
+The `left-fringe', `right-fringe', `left-margin', `right-margin',
+`scroll-bar', and `text' elements specify to the width of the
+corresponding area of the window.
+
+The `left', `center', and `right' positions can be used with :align-to
+to specify a position relative to the left edge, center, or right edge
+of the text area. One of the above window elements (except `text')
+can also be used with :align-to to specify that the position is
+relative to the left edge of the given area. Once the base offset for
+a relative position has been set (by the first occurrence of one of
+these symbols), further occurrences of these symbols are interpreted as
+the width of the area.
+
+For example, to align to the center of the left-margin, use
+ :align-to (+ left-margin (0.5 . left-margin))
+
+If no specific base offset is set for alignment, it is always relative
+to the left edge of the text area. For example, :align-to 0 in a
+header line aligns with the first text column in the text area.
+
+The value of the form `(NUM . EXPR)' is the value of NUM multiplied by
+the value of the expression EXPR. For example, (2 . in) specifies a
+width of 2 inches, while (0.5 . IMAGE) specifies half the width (or
+height) of the specified image.
+
+The form `(+ EXPR ...)' adds up the value of the expressions.
+The form `(- EXPR ...)' negates or subtracts the value of the expressions.
+
+*** Normally, the cursor is displayed at the end of any overlay and
+text property string that may be present at the current window
+position. The cursor can now be placed on any character of such
+strings by giving that character a non-nil `cursor' text property.
+
+*** The display space :width and :align-to text properties are now
+supported on text terminals.
+
+*** Support for displaying image slices
+
+**** New display property (slice X Y WIDTH HEIGHT) can be used with
+an image property to display only a specific slice of the image.
+
+**** Function `insert-image' has new optional fourth arg to
+specify image slice (X Y WIDTH HEIGHT).
+
+**** New function `insert-sliced-image' inserts a given image as a
+specified number of evenly sized slices (rows x columns).
+
+*** Images can now have an associated image map via the :map property.
+
+An image map is an alist where each element has the format (AREA ID PLIST).
+An AREA is specified as either a rectangle, a circle, or a polygon:
+A rectangle is a cons (rect . ((X0 . Y0) . (X1 . Y1))) specifying the
+pixel coordinates of the upper left and bottom right corners.
+A circle is a cons (circle . ((X0 . Y0) . R)) specifying the center
+and the radius of the circle; R can be a float or integer.
+A polygon is a cons (poly . [X0 Y0 X1 Y1 ...]) where each pair in the
+vector describes one corner in the polygon.
+
+When the mouse pointer is above a hot-spot area of an image, the
+PLIST of that hot-spot is consulted; if it contains a `help-echo'
+property it defines a tool-tip for the hot-spot, and if it contains
+a `pointer' property, it defines the shape of the mouse cursor when
+it is over the hot-spot. See the variable `void-area-text-pointer'
+for possible pointer shapes.
+
+When you click the mouse when the mouse pointer is over a hot-spot,
+an event is composed by combining the ID of the hot-spot with the
+mouse event, e.g. [area4 mouse-1] if the hot-spot's ID is `area4'.
+
+*** The function `find-image' now searches in etc/images/ and etc/.
+The new variable `image-load-path' is a list of locations in which to
+search for image files. The default is to search in etc/images, then
+in etc/, and finally in the directories specified by `load-path'.
+Subdirectories of etc/ and etc/images are not recursively searched; if
+you put an image file in a subdirectory, you have to specify it
+explicitly; for example, if an image is put in etc/images/foo/bar.xpm:
+
+ (defimage foo-image '((:type xpm :file "foo/bar.xpm")))
+
+Note that all images formerly located in the lisp directory have been
+moved to etc/images.
+
+*** New function `image-load-path-for-library' returns a suitable
+search path for images relative to library. This function is useful in
+external packages to save users from having to update
+`image-load-path'.
+
+*** The new variable `max-image-size' defines the maximum size of
+images that Emacs will load and display.
+
+*** The new variable `display-mm-dimensions-alist' can be used to
+override incorrect graphical display dimensions returned by functions
+`display-mm-height' and `display-mm-width'.
+
+** Mouse pointer features:
+
+*** The mouse pointer shape in void text areas (i.e. after the end of a
+line or below the last line in the buffer) of the text window is now
+controlled by the new variable `void-text-area-pointer'. The default
+is to use the `arrow' (non-text) pointer. Other choices are `text'
+(or nil), `hand', `vdrag', `hdrag', `modeline', and `hourglass'.
+
+*** The mouse pointer shape over an image can now be controlled by the
+:pointer image property.
+
+*** The mouse pointer shape over ordinary text or images can now be
+controlled/overridden via the `pointer' text property.
+
+** Mouse event enhancements:
+
+*** All mouse events now include a buffer position regardless of where
+you clicked. For mouse clicks in window margins and fringes, this is
+a sensible buffer position corresponding to the surrounding text.
+
+*** Mouse events for clicks on window fringes now specify `left-fringe'
+or `right-fringe' as the area.
+
+*** Mouse events include actual glyph column and row for all event types
+and all areas.
+
+*** Mouse events can now indicate an image object clicked on.
+
+*** Mouse events include relative X and Y pixel coordinates relative to
+the top left corner of the object (image or character) clicked on.
+
+*** Mouse events include the pixel width and height of the object
+(image or character) clicked on.
+
+*** Function `mouse-set-point' now works for events outside text area.
+
+*** `posn-point' now returns buffer position for non-text area events.
+
+*** New function `posn-area' returns window area clicked on (nil means
+text area).
+
+*** New function `posn-actual-col-row' returns the actual glyph coordinates
+of the mouse event position.
+
+*** New functions 'posn-object', 'posn-object-x-y', 'posn-object-width-height'.
+
+These return the image or string object of a mouse click, the X and Y
+pixel coordinates relative to the top left corner of that object, and
+the total width and height of that object.
+
+** Text property and overlay changes:
+
+*** Arguments for `remove-overlays' are now optional, so that you can
+remove all overlays in the buffer with just (remove-overlays).
+
+*** New variable `char-property-alias-alist'.
+
+This variable allows you to create alternative names for text
+properties. It works at the same level as `default-text-properties',
+although it applies to overlays as well. This variable was introduced
+to implement the `font-lock-face' property.
+
+*** New function `get-char-property-and-overlay' accepts the same
+arguments as `get-char-property' and returns a cons whose car is the
+return value of `get-char-property' called with those arguments and
+whose cdr is the overlay in which the property was found, or nil if
+it was found as a text property or not found at all.
+
+*** The new function `remove-list-of-text-properties'.
+
+It is like `remove-text-properties' except that it takes a list of
+property names as argument rather than a property list.
+
+** Face changes
+
+*** The variable `facemenu-unlisted-faces' has been removed.
+Emacs has a lot more faces than in the past, and nearly all of them
+needed to be excluded. The new variable `facemenu-listed-faces' lists
+the faces to include in the face menu.
+
+*** The new face attribute condition `min-colors' can be used to tailor
+the face color to the number of colors supported by a display, and
+define the foreground and background colors accordingly so that they
+look best on a terminal that supports at least this many colors. This
+is now the preferred method for defining default faces in a way that
+makes a good use of the capabilities of the display.
+
+*** New function `display-supports-face-attributes-p' can be used to test
+whether a given set of face attributes is actually displayable.
+
+A new predicate `supports' has also been added to the `defface' face
+specification language, which can be used to do this test for faces
+defined with `defface'.
+
+*** The special treatment of faces whose names are of the form `fg:COLOR'
+or `bg:COLOR' has been removed. Lisp programs should use the
+`defface' facility for defining faces with specific colors, or use
+the feature of specifying the face attributes :foreground and :background
+directly in the `face' property instead of using a named face.
+
+*** The first face specification element in a defface can specify
+`default' instead of frame classification. Then its attributes act as
+defaults that apply to all the subsequent cases (and can be overridden
+by them).
+
+*** The function `face-differs-from-default-p' now truly checks
+whether the given face displays differently from the default face or
+not (previously it did only a very cursory check).
+
+*** `face-attribute', `face-foreground', `face-background', `face-stipple'.
+
+These now accept a new optional argument, INHERIT, which controls how
+face inheritance is used when determining the value of a face
+attribute.
+
+*** New functions `face-attribute-relative-p' and `merge-face-attribute'
+help with handling relative face attributes.
+
+*** The priority of faces in an :inherit attribute face list is reversed.
+
+If a face contains an :inherit attribute with a list of faces, earlier
+faces in the list override later faces in the list; in previous
+releases of Emacs, the order was the opposite. This change was made
+so that :inherit face lists operate identically to face lists in text
+`face' properties.
+
+*** The variable `face-font-rescale-alist' specifies how much larger
+(or smaller) font we should use. For instance, if the value is
+'((SOME-FONTNAME-PATTERN . 1.3)) and a face requests a font of 10
+point, we actually use a font of 13 point if the font matches
+SOME-FONTNAME-PATTERN.
+
+*** On terminals, faces with the :inverse-video attribute are displayed
+with swapped foreground and background colors even when one of them is
+not specified. In previous releases of Emacs, if either foreground
+or background color was unspecified, colors were not swapped. This
+was inconsistent with the face behavior under X.
+
+*** `set-fontset-font', `fontset-info', `fontset-font' now operate on
+the default fontset if the argument NAME is nil..
+
+** Font-Lock changes:
+
+*** New special text property `font-lock-face'.
+
+This property acts like the `face' property, but it is controlled by
+M-x font-lock-mode. It is not, strictly speaking, a builtin text
+property. Instead, it is implemented inside font-core.el, using the
+new variable `char-property-alias-alist'.
+
+*** font-lock can manage arbitrary text-properties beside `face'.
+
+**** the FACENAME returned in `font-lock-keywords' can be a list of the
+form (face FACE PROP1 VAL1 PROP2 VAL2 ...) so you can set other
+properties than `face'.
+
+**** `font-lock-extra-managed-props' can be set to make sure those
+extra properties are automatically cleaned up by font-lock.
+
+*** jit-lock obeys a new text-property `jit-lock-defer-multiline'.
+
+If a piece of text with that property gets contextually refontified
+(see `jit-lock-defer-contextually'), then all of that text will
+be refontified. This is useful when the syntax of a textual element
+depends on text several lines further down (and when `font-lock-multiline'
+is not appropriate to solve that problem). For example in Perl:
+
+ s{
+ foo
+ }{
+ bar
+ }e
+
+Adding/removing the last `e' changes the `bar' from being a piece of
+text to being a piece of code, so you'd put a `jit-lock-defer-multiline'
+property over the second half of the command to force (deferred)
+refontification of `bar' whenever the `e' is added/removed.
+
+*** `font-lock-extend-region-functions' makes it possible to alter the way
+the fontification region is chosen. This can be used to prevent rounding
+up to whole lines, or to extend the region to include all related lines
+of multiline constructs so that such constructs get properly recognized.
+
+** Major mode mechanism changes:
+
+*** New variable `magic-mode-alist' determines major mode for a file by
+looking at the file contents. It takes precedence over `auto-mode-alist'.
+
+*** New variable `magic-fallback-mode-alist' determines major mode for a file by
+looking at the file contents. It is handled after `auto-mode-alist',
+only if `auto-mode-alist' (and `magic-mode-alist') says nothing about the file.
+
+*** XML or SGML major mode is selected when file starts with an `<?xml'
+or `<!DOCTYPE' declaration.
+
+*** An interpreter magic line (if present) takes precedence over the
+file name when setting the major mode.
+
+*** If new variable `auto-mode-case-fold' is set to a non-nil value,
+Emacs will perform a second case-insensitive search through
+`auto-mode-alist' if the first case-sensitive search fails. This
+means that a file FILE.TXT is opened in text-mode, and a file
+PROG.HTML is opened in html-mode. Note however, that independent of
+this setting, *.C files are usually recognized as C++ files. It also
+has no effect on systems with case-insensitive file names.
+
+*** All major mode functions should now run the new normal hook
+`after-change-major-mode-hook', at their very end, after the mode
+hooks. `run-mode-hooks' does this automatically.
+
+*** Major modes can define `eldoc-documentation-function'
+locally to provide Eldoc functionality by some method appropriate to
+the language.
+
+*** Use the new function `run-mode-hooks' to run the major mode's mode hook.
+
+*** The new function `run-mode-hooks' and the new macro `delay-mode-hooks'
+are used by `define-derived-mode' to make sure the mode hook for the
+parent mode is run at the end of the child mode.
+
+*** `define-derived-mode' by default creates a new empty abbrev table.
+It does not copy abbrevs from the parent mode's abbrev table.
+
+*** If a major mode function has a non-nil `no-clone-indirect'
+property, `clone-indirect-buffer' signals an error if you use
+it in that buffer.
+
+** Minor mode changes:
+
+*** `define-minor-mode' now accepts arbitrary additional keyword arguments
+and simply passes them to `defcustom', if applicable.
+
+*** `define-globalized-minor-mode'.
+
+This is a new name for what was formerly called
+`easy-mmode-define-global-mode'. The old name remains as an alias.
+
+*** `minor-mode-list' now holds a list of minor mode commands.
+
+** Command loop changes:
+
+*** The new function `called-interactively-p' does what many people
+have mistakenly believed `interactive-p' to do: it returns t if the
+calling function was called through `call-interactively'.
+
+Only use this when you cannot solve the problem by adding a new
+INTERACTIVE argument to the command.
+
+*** The function `commandp' takes an additional optional argument.
+
+If it is non-nil, then `commandp' checks for a function that could be
+called with `call-interactively', and does not return t for keyboard
+macros.
+
+*** When a command returns, the command loop moves point out from
+within invisible text, in the same way it moves out from within text
+covered by an image or composition property.
+
+This makes it generally unnecessary to mark invisible text as intangible.
+This is particularly good because the intangible property often has
+unexpected side-effects since the property applies to everything
+(including `goto-char', ...) whereas this new code is only run after
+`post-command-hook' and thus does not care about intermediate states.
+
+*** If a command sets `transient-mark-mode' to `only', that
+enables Transient Mark mode for the following command only.
+During that following command, the value of `transient-mark-mode'
+is `identity'. If it is still `identity' at the end of the command,
+the next return to the command loop changes to nil.
+
+*** Both the variable and the function `disabled-command-hook' have
+been renamed to `disabled-command-function'. The variable
+`disabled-command-hook' has been kept as an obsolete alias.
+
+*** `emacsserver' now runs `pre-command-hook' and `post-command-hook'
+when it receives a request from emacsclient.
+
+*** `current-idle-time' reports how long Emacs has been idle.
+
+** Lisp file loading changes:
+
+*** `load-history' can now have elements of the form (t . FUNNAME),
+which means FUNNAME was previously defined as an autoload (before the
+current file redefined it).
+
+*** `load-history' now records (defun . FUNNAME) when a function is
+defined. For a variable, it records just the variable name.
+
+*** The function `symbol-file' can now search specifically for function,
+variable or face definitions.
+
+*** `provide' and `featurep' now accept an optional second argument
+to test/provide subfeatures. Also `provide' now checks `after-load-alist'
+and runs any code associated with the provided feature.
+
+*** The variable `recursive-load-depth-limit' has been deleted.
+Emacs now signals an error if the same file is loaded with more
+than 3 levels of nesting.
+
+** Byte compiler changes:
+
+*** The byte compiler now displays the actual line and character
+position of errors, where possible. Additionally, the form of its
+warning and error messages have been brought into line with GNU standards
+for these. As a result, you can use next-error and friends on the
+compilation output buffer.
+
+*** The new macro `with-no-warnings' suppresses all compiler warnings
+inside its body. In terms of execution, it is equivalent to `progn'.
+
+*** You can avoid warnings for possibly-undefined symbols with a
+simple convention that the compiler understands. (This is mostly
+useful in code meant to be portable to different Emacs versions.)
+Write forms like the following, or code that macroexpands into such
+forms:
+
+ (if (fboundp 'foo) <then> <else>)
+ (if (boundp 'foo) <then> <else)
+
+In the first case, using `foo' as a function inside the <then> form
+won't produce a warning if it's not defined as a function, and in the
+second case, using `foo' as a variable won't produce a warning if it's
+unbound. The test must be in exactly one of the above forms (after
+macro expansion), but such tests can be nested. Note that `when' and
+`unless' expand to `if', but `cond' doesn't.
+
+*** `(featurep 'xemacs)' is treated by the compiler as nil. This
+helps to avoid noisy compiler warnings in code meant to run under both
+Emacs and XEmacs and can sometimes make the result significantly more
+efficient. Since byte code from recent versions of XEmacs won't
+generally run in Emacs and vice versa, this optimization doesn't lose
+you anything.
+
+*** The local variable `no-byte-compile' in Lisp files is now obeyed.
+
+*** When a Lisp file uses CL functions at run-time, compiling the file
+now issues warnings about these calls, unless the file performs
+(require 'cl) when loaded.
+
+** Frame operations:
+
+*** New functions `frame-current-scroll-bars' and `window-current-scroll-bars'.
+
+These functions return the current locations of the vertical and
+horizontal scroll bars in a frame or window.
+
+*** The new function `modify-all-frames-parameters' modifies parameters
+for all (existing and future) frames.
+
+*** The new frame parameter `tty-color-mode' specifies the mode to use
+for color support on character terminal frames. Its value can be a
+number of colors to support, or a symbol. See the Emacs Lisp
+Reference manual for more detailed documentation.
+
+*** When using non-toolkit scroll bars with the default width,
+the `scroll-bar-width' frame parameter value is nil.
+
+** Mode line changes:
+
+*** New function `format-mode-line'.
+
+This returns the mode line or header line of the selected (or a
+specified) window as a string with or without text properties.
+
+*** The new mode-line construct `(:propertize ELT PROPS...)' can be
+used to add text properties to mode-line elements.
+
+*** The new `%i' and `%I' constructs for `mode-line-format' can be used
+to display the size of the accessible part of the buffer on the mode
+line.
+
+*** Mouse-face on mode-line (and header-line) is now supported.
+
+** Menu manipulation changes:
+
+*** To manipulate the File menu using easy-menu, you must specify the
+proper name "file". In previous Emacs versions, you had to specify
+"files", even though the menu item itself was changed to say "File"
+several versions ago.
+
+*** The dummy function keys made by easy-menu are now always lower case.
+If you specify the menu item name "Ada", for instance, it uses `ada'
+as the "key" bound by that key binding.
+
+This is relevant only if Lisp code looks for the bindings that were
+made with easy-menu.
+
+*** `easy-menu-define' now allows you to use nil for the symbol name
+if you don't need to give the menu a name. If you install the menu
+into other keymaps right away (MAPS is non-nil), it usually doesn't
+need to have a name.
+
+** Mule changes:
+
+*** Already true in Emacs 21.1, but not emphasized clearly enough:
+
+Multibyte buffers can now faithfully record all 256 character codes
+from 0 to 255. As a result, most of the past reasons to use unibyte
+buffers no longer exist. We only know of three reasons to use them
+now:
+
+1. If you prefer to use unibyte text all of the time.
+
+2. For reading files into temporary buffers, when you want to avoid
+the time it takes to convert the format.
+
+3. For binary files where format conversion would be pointless and
+wasteful.
+
+*** The new variable `auto-coding-functions' lets you specify functions
+to examine a file being visited and deduce the proper coding system
+for it. (If the coding system is detected incorrectly for a specific
+file, you can put a `coding:' tags to override it.)
+
+*** The new variable `ascii-case-table' stores the case table for the
+ascii character set. Language environments (such as Turkish) may
+alter the case correspondences of ASCII characters. This variable
+saves the original ASCII case table before any such changes.
+
+*** The new function `merge-coding-systems' fills in unspecified aspects
+of one coding system from another coding system.
+
+*** New coding system property `mime-text-unsuitable' indicates that
+the coding system's `mime-charset' is not suitable for MIME text
+parts, e.g. utf-16.
+
+*** New function `decode-coding-inserted-region' decodes a region as if
+it is read from a file without decoding.
+
+*** New CCL functions `lookup-character' and `lookup-integer' access
+hash tables defined by the Lisp function `define-translation-hash-table'.
+
+*** New function `quail-find-key' returns a list of keys to type in the
+current input method to input a character.
+
+*** `set-buffer-file-coding-system' now takes an additional argument,
+NOMODIFY. If it is non-nil, it means don't mark the buffer modified.
+
+** Operating system access:
+
+*** The new primitive `get-internal-run-time' returns the processor
+run time used by Emacs since start-up.
+
+*** Functions `user-uid' and `user-real-uid' now return floats if the
+user UID doesn't fit in a Lisp integer. Function `user-full-name'
+accepts a float as UID parameter.
+
+*** New function `locale-info' accesses locale information.
+
+*** On MS Windows, locale-coding-system is used to interact with the OS.
+The Windows specific variable w32-system-coding-system, which was
+formerly used for that purpose is now an alias for locale-coding-system.
+
+*** New function `redirect-debugging-output' can be used to redirect
+debugging output on the stderr file handle to a file.
+
+** GC changes:
+
+*** New variable `gc-cons-percentage' automatically grows the GC cons threshold
+as the heap size increases.
+
+*** New variables `gc-elapsed' and `gcs-done' provide extra information
+on garbage collection.
+
+*** The normal hook `post-gc-hook' is run at the end of garbage collection.
+
+The hook is run with GC inhibited, so use it with care.
+
+** Miscellaneous:
+
+*** A number of hooks have been renamed to better follow the conventions:
+
+`find-file-hooks' to `find-file-hook',
+`find-file-not-found-hooks' to `find-file-not-found-functions',
+`write-file-hooks' to `write-file-functions',
+`write-contents-hooks' to `write-contents-functions',
+`x-lost-selection-hooks' to `x-lost-selection-functions',
+`x-sent-selection-hooks' to `x-sent-selection-functions',
+`delete-frame-hook' to `delete-frame-functions'.
+
+In each case the old name remains as an alias for the moment.
+
+*** Variable `local-write-file-hooks' is marked obsolete.
+
+Use the LOCAL arg of `add-hook'.
+
+*** New function `x-send-client-message' sends a client message when
+running under X.
+\f
+* New Packages for Lisp Programming in Emacs 22.1
+
+** The new library button.el implements simple and fast `clickable
+buttons' in Emacs buffers. Buttons are much lighter-weight than the
+`widgets' implemented by widget.el, and can be used by lisp code that
+doesn't require the full power of widgets. Emacs uses buttons for
+such things as help and apropos buffers.
+
+** The new library tree-widget.el provides a widget to display a set
+of hierarchical data as an outline. For example, the tree-widget is
+well suited to display a hierarchy of directories and files.
+
+** The new library bindat.el provides functions to unpack and pack
+binary data structures, such as network packets, to and from Lisp
+data structures.
+
+** master-mode.el implements a minor mode for scrolling a slave
+buffer without leaving your current buffer, the master buffer.
+
+It can be used by sql.el, for example: the SQL buffer is the master
+and its SQLi buffer is the slave. This allows you to scroll the SQLi
+buffer containing the output from the SQL buffer containing the
+commands.
+
+This is how to use sql.el and master.el together: the variable
+sql-buffer contains the slave buffer. It is a local variable in the
+SQL buffer.
+
+(add-hook 'sql-mode-hook
+ (function (lambda ()
+ (master-mode t)
+ (master-set-slave sql-buffer))))
+(add-hook 'sql-set-sqli-hook
+ (function (lambda ()
+ (master-set-slave sql-buffer))))
+
+** The new library benchmark.el does timing measurements on Lisp code.
+
+This includes measuring garbage collection time.
+
+** The new library testcover.el does test coverage checking.
+
+This is so you can tell whether you've tested all paths in your Lisp
+code. It works with edebug.
+
+The function `testcover-start' instruments all functions in a given
+file. Then test your code. The function `testcover-mark-all' adds
+overlay "splotches" to the Lisp file's buffer to show where coverage
+is lacking. The command `testcover-next-mark' (bind it to a key!)
+will move point forward to the next spot that has a splotch.
+
+Normally, a red splotch indicates the form was never completely
+evaluated; a brown splotch means it always evaluated to the same
+value. The red splotches are skipped for forms that can't possibly
+complete their evaluation, such as `error'. The brown splotches are
+skipped for forms that are expected to always evaluate to the same
+value, such as (setq x 14).
+
+For difficult cases, you can add do-nothing macros to your code to
+help out the test coverage tool. The macro `noreturn' suppresses a
+red splotch. It is an error if the argument to `noreturn' does
+return. The macro `1value' suppresses a brown splotch for its argument.
+This macro is a no-op except during test-coverage -- then it signals
+an error if the argument actually returns differing values.
