* Changes in Emacs 21.1
+** Emacs has a new redisplay engine.
+
+The new redisplay handles characters of variable width and height.
+Italic text can be used without redisplay problems. Fonts containing
+oversized characters, i.e. characters larger than the logical height
+of a font can be used. Images of various formats can be displayed in
+the text.
+
+** Emacs has a new face implementation.
+
+The new faces no longer fundamentally use X font names to specify the
+font. Instead, each face has several independent attributes--family,
+height, width, weight and slant--that it may or may not specify.
+These attributes can be merged from various faces, and then together
+specify a font.
+
+Faces are supported on terminals that can display color or fonts.
+These terminal capabilities are auto-detected. Details can be found
+under Lisp changes, below.
+
+** Emacs can display faces on TTY frames.
+
+Emacs automatically detects terminals that are able to display colors.
+Faces with a weight greater than normal are displayed extra-bright, if
+the terminal supports it. Faces with a weight less than normal and
+italic faces are displayed dimmed, if the terminal supports it.
+Underlined faces are displayed underlined if possible. Other face
+attributes such as `overline', `strike-through', and `box' are ignored
+on terminals.
+
+The command-line options `-fg COLOR', `-bg COLOR', and `-rv' are now
+supported on character terminals.
+
+** New default font is Courier 12pt under X.
+
++++
+** Emacs now resizes mini-windows if appropriate.
+
+If a message is longer than one line, or minibuffer contents are
+longer than one line, Emacs can resize the minibuffer window unless it
+is on a frame of its own. You can control resizing and the maximum
+minibuffer window size by setting the following variables:
+
+- User option: max-mini-window-height
+
+Maximum height for resizing mini-windows. If a float, it specifies a
+fraction of the mini-window frame's height. If an integer, it
+specifies a number of lines.
+
+Default is 0.25.
+
+- User option: resize-mini-windows
+
+How to resize mini-windows. If nil, don't resize. If t, always
+resize to fit the size of the text. If `grow-only', let mini-windows
+grow only, until they become empty, at which point they are shrunk
+again.
+
+Default is `grow-only'.
+
+** LessTif support.
+
+Emacs now runs with the LessTif toolkit (see
+<http://www.lesstif.org>). You will need version 0.92 or later.
+
+** LessTif/Motif file selection dialog.
+
+When Emacs is configured to use LessTif or Motif, reading a file name
+from a menu will pop up a file selection dialog if `use-dialog-box' is
+non-nil.
+
+** Toolkit scroll bars.
+
+Emacs now uses toolkit scroll bars if available. When configured for
+LessTif/Motif, it will use that toolkit's scroll bar. Otherwise, when
+configured for Lucid and Athena widgets, it will use the Xaw3d scroll
+bar if Xaw3d is available. You can turn off the use of toolkit scroll
+bars by specifying `--with-toolkit-scroll-bars=no' when configuring
+Emacs.
+
+When you encounter problems with the Xaw3d scroll bar, watch out how
+Xaw3d is compiled on your system. If the Makefile generated from
+Xaw3d's Imakefile contains a `-DNARROWPROTO' compiler option, and your
+Emacs system configuration file `s/your-system.h' does not contain a
+define for NARROWPROTO, you might consider adding it. Take
+`s/freebsd.h' as an example.
+
+Alternatively, if you don't have access to the Xaw3d source code, take
+a look at your system's imake configuration file, for example in the
+directory `/usr/X11R6/lib/X11/config' (paths are different on
+different systems). You will find files `*.cf' there. If your
+system's cf-file contains a line like `#define NeedWidePrototypes NO',
+add a `#define NARROWPROTO' to your Emacs system configuration file.
+
+The reason for this is that one Xaw3d function uses `double' or
+`float' function parameters depending on the setting of NARROWPROTO.
+This is not a problem when Imakefiles are used because each system's
+image configuration file contains the necessary information. Since
+Emacs doesn't use imake, this has do be done manually.
+
++++
+** Automatic Hscrolling
+
+Horizontal scrolling now happens automatically if
+`automatic-hscrolling' is set (the default). This setting can be
+customized.
+
+If a window is scrolled horizontally with set-window-hscroll, or
+scroll-left/scroll-right (C-x <, C-x >), this serves as a lower bound
+for automatic horizontal scrolling. Automatic scrolling will scroll
+the text more to the left if necessary, but won't scroll the text more
+to the right than the column set with set-window-hscroll etc.
+
++++
+** Tool bar support.
+
+Emacs supports a tool bar at the top of a frame under X. For details
+of how to define a tool bar, see the page describing Lisp-level
+changes. Tool-bar global minor mode controls whether or not it is
+displayed and is on by default. The appearance of the bar is improved
+if Emacs has been built with XPM image support. Otherwise monochrome
+icons will be used.
+
+To make the tool bar more useful, we need contributions of extra icons
+for specific modes (with copyright assignments). Contributions would
+also be useful manually to touch up some of the PBM icons.
+
++++
+** Tooltips.
+
+Tooltips are small X windows displaying a help string at the current
+mouse position. The Lisp package `tooltip' implements them. You can
+turn them off via the user option `tooltip-mode'.
+
+Tooltips also provides support for GUD debugging. If activated,
+variable values can be displayed in tooltips by pointing at them with
+the mouse in source buffers. You can customize various aspects of the
+tooltip display in the group `tooltip'.
+
++++
+** When using a windowing terminal, each Emacs window now has a cursor
+of its own. By default, when a window is selected, the cursor is
+solid; otherwise, it is hollow. The user-option
+`show-cursor-in-non-selected-windows' controls how to display the
+cursor in non-selected windows. If nil, no cursor is shown, if
+non-nil a hollow box cursor is shown. This option can be customized.
+
+** Fringes to the left and right of windows are used to display
+truncation marks, continuation marks, overlay arrows and alike. The
+foreground, background, and stipple of these areas can be changed by
+customizing face `fringe'.
+
+** The mode line under X is now drawn with shadows by default.
+You can change its appearance by modifying the face `mode-line'.
+In particular, setting the `:box' attribute to nil turns off the 3D
+appearance of the mode line. (The 3D appearance makes the mode line
+occupy more space, and thus might cause the first or the last line of
+the window to be partially obscured.)
+
+The variable `mode-line-inverse-video', which was used in older
+versions of emacs to make the mode-line stand out, now defaults to nil,
+and its use is deprecated.
+
++++
+** Mouse-sensitive mode line.
+
+Different parts of the mode line under X have been made
+mouse-sensitive. Moving the mouse to a mouse-sensitive part in the mode
+line changes the appearance of the mouse pointer to an arrow, and help
+about available mouse actions is displayed either in the echo area, or
+in the tooltip window if you have enabled one.
+
+Currently, the following actions have been defined:
+
+- Mouse-1 on the buffer name in the mode line switches between two
+buffers.
+
+- Mouse-2 on the buffer-name switches to the next buffer, and
+M-mouse-2 switches to the previous buffer in the buffer list.
+
+- Mouse-3 on the buffer-name displays a buffer menu.
+
+- Mouse-2 on the read-only or modified status in the mode line (`%' or
+`*') toggles the status.
+
+- Mouse-3 on the mode name displays a minor-mode menu.
+
++++
+** Hourglass pointer
+
+Emacs can optionally display an hourglass pointer under X. You can
+turn the display on or off by customizing group `cursor'.
+
++++
+** Blinking cursor
+
+M-x blink-cursor-mode toggles a blinking cursor under X and on
+terminals having terminal capabilities `vi', `vs', and `ve'. Blinking
+and related parameters like frequency and delay can be customized in
+the group `cursor'.
+
++++
+** New font-lock support mode `jit-lock-mode'.
+
+This support mode is roughly equivalent to `lazy-lock' but is
+generally faster. It supports stealth and deferred fontification.
+See the documentation of the function `jit-lock-mode' for more
+details.
+
+Font-lock uses jit-lock-mode as default support mode, so you don't
+have to do anything to activate it.
+
++++
+** The default for user-option `next-line-add-newlines' has been
+changed to nil, i.e. C-n will no longer add newlines at the end of a
+buffer by default.
+
+** The <home> and <end> keys now move to the beginning or end of the
+current line, respectively. C-<home> and C-<end> move to the
+beginning and end of the buffer.
+
+** Emacs now checks for recursive loads of Lisp files. If the
+recursion depth exceeds `recursive-load-depth-limit', an error is
+signaled.
+
+** When an error is signaled during the loading of the user's init
+file, Emacs now pops up the *Messages* buffer.
+
++++
+** Emacs now refuses to load compiled Lisp files which weren't
+compiled with Emacs. Set `load-dangerous-libraries' to t to change
+this behavior.
+
+The reason for this change is an incompatible change in XEmacs' byte
+compiler. Files compiled with XEmacs can contain byte codes that let
+Emacs dump core.
+
+** Toggle buttons and radio buttons in menus.
+
+When compiled with LessTif (or Motif) support, Emacs uses toolkit
+widgets for radio and toggle buttons in menus. When configured for
+Lucid, Emacs draws radio buttons and toggle buttons similar to Motif.
+
+** The menu bar configuration has changed. The new configuration is
+more CUA-compliant. The most significant change is that Options is
+now a separate menu-bar item, with Mule and Customize as its submenus.
+
+** Item Save Options on the Options menu allows saving options set
+using that menu.
+
++++
+** Highlighting of trailing whitespace.
+
+When `show-trailing-whitespace' is non-nil, Emacs displays trailing
+whitespace in the face `trailing-whitespace'. Trailing whitespace is
+defined as spaces or tabs at the end of a line. To avoid busy
+highlighting when entering new text, trailing whitespace is not
+displayed if point is at the end of the line containing the
+whitespace.
+
++++
+** C-x 5 1 runs the new command delete-other-frames which deletes
+all frames except the selected one.
+
+** The new user-option `confirm-kill-emacs' can be customized to
+let Emacs ask for confirmation before exiting.
+
++++
+** Highlighting of mouse-sensitive regions is now supported in the
+MS-DOS version of Emacs.
+
+** The header line in an Info buffer is now displayed as an emacs
+header-line (which is like a mode-line, but at the top of the window),
+so that it remains visible even when the buffer has been scrolled.
+This behavior may be disabled by customizing the option
+`Info-use-header-line'.
+
++++
+** The recommended way of using Iswitchb is via the new global minor
+mode `iswitchb-mode'.
+
++++
+** Just loading the msb package doesn't switch on Msb mode anymore.
+If you have `(require 'msb)' in your .emacs, please replace it with
+`(msb-mode 1)'.
+
+** Polish, Czech, German, and French translations of Emacs' reference card
+have been added. They are named `pl-refcard.tex', `cs-refcard.tex',
+`de-refcard.tex' and `fr-refcard.tex'. Postscript files are included.
+
+** An `Emacs Survival Guide', etc/survival.tex, is available.
+
+** A reference card for Dired has been added. Its name is
+`dired-ref.tex'. A French translation is available in
+`fr-drdref.tex'.
+
++++
+** C-down-mouse-3 is bound differently. Now if the menu bar is not
+displayed it pops up a menu containing the items which would be on the
+menu bar. If the menu bar is displayed, it pops up the major mode
+menu or the Edit menu if there is no major mode menu.
+
+** Variable `load-path' is no longer customizable because it contains
+a version-dependent component.
+
+** The new user-option `delete-key-deletes-forward' can be set to
+let the Delete function key delete forward instead of backward.
+
+On window systems, the default value of this option is chosen
+according to the keyboard used. If the keyboard has both a Backspace
+key and a Delete key, and both are mapped to their usual meanings, the
+option's default value is set to t, so that Backspace can be used to
+delete backward, and Delete can be used to delete forward.
+
+If not running under a window system, setting this option accomplishes
+a similar effect by mapping C-h, which is usually generated by the
+Backspace key, to DEL, and by mapping DEL to C-d via
+`keyboard-translate'. The former functionality of C-h is available on
+the F1 key. You should probably not use this setting if you don't
+have both Backspace, Delete and F1 keys.
+
+Programmatically, you can call function
+delete-key-deletes-forward-mode to toggle the behavior of the Delete
+key.
+
++++
+** C-u C-x = provides detailed information about the character at
+point in a pop-up window.
+
++++
+** Emacs can now support 'wheeled' mice (such as the MS IntelliMouse)
+under XFree86. To enable this, use the `mouse-wheel-mode' command, or
+customize the variable `mouse-wheel-mode'.
+
+The variables `mouse-wheel-follow-mouse' and `mouse-wheel-scroll-amount'
+determine where and by how much buffers are scrolled.
+
++++
+** Emacs' auto-save list files are now by default stored in a
+sub-directory `.emacs.d/auto-save-list/' of the user's home directory.
+(On MS-DOS, this subdirectory's name is `_emacs.d/auto-save.list/'.)
+You can customize `auto-save-list-prefix' to change this location.
+
++++
+** The function `getenv' is now callable interactively.
+
+** The many obsolete language `setup-...-environment' commands have
+been removed -- use `set-language-environment'.
+
+++
** The environment variable `EMACSLOCKDIR' is no longer used on MS-Windows.
This environment variable was used when creating lock files. Emacs on

-** The new user-option `confirm-kill-emacs' can be customized to
-let Emacs ask for confirmation before exiting.
-
-** The <home> and <end> keys now move to the beginning or end of the
-current line, respectively. C-<home> and C-<end> move to the
-beginning and end of the buffer.
-
** In Cperl mode `cperl-invalid-face' should now be a normal face
symbol, not double-quoted.
example is the wheeled mice, which report 3 buttons, but clicks on the
middle button are not passed to the MS-DOS version of Emacs.
-+++
-** The default for user-option `next-line-add-newlines' has been
-changed to nil, i.e. C-n will no longer add newlines at the end of a
-buffer by default.
-
** The new command M-x delete-trailing-whitespace RET will delete the
trailing whitespace within the current restriction. You can also add
this function to `write-file-hooks' or `local-write-file-hooks'.
** The functions `keep-lines', `flush-lines' and `how-many' now
operate on the active region in Transient Mark mode.
-** The header line in an Info buffer is now displayed as an emacs header-line
-(which is like a mode-line, but at the top of the window), so that it
-remains visible even when the buffer has been scrolled. This behavior
-may be disabled by customizing the option `Info-use-header-line'.
-
+++
** `gnus-user-agent' is a new possibility for `mail-user-agent'. It
is like `message-user-agent', but with all the Gnus paraphernalia.
-+++
-** The recommended way of using Iswitchb is via the new global minor
-mode `iswitchb-mode'.
-
+++
** Gnus changes.
** The new user-option `electric-help-shrink-window' can be set to
nil to prevent adjusting the help window size to the buffer size.
-** Emacs now checks for recursive loads of Lisp files. If the
-recursion depth exceeds `recursive-load-depth-limit', an error is
-signaled.
-
** The Strokes package has been updated. If your Emacs has XPM
support, you can use it for pictographic editing. In Strokes mode,
use C-mouse-2 to compose a complex stoke and insert it into the
** New command M-x describe-character-set reads a character set name
and displays information about that.
-** When an error is signaled during the loading of the user's init
-file, Emacs now pops up the *Messages* buffer.
-
-** Polish, Czech, German, and French translations of Emacs' reference card
-have been added. They are named `pl-refcard.tex', `cs-refcard.tex',
-`de-refcard.tex' and `fr-refcard.tex'. Postscript files are included.
-
-** An `Emacs Survival Guide', etc/survival.tex, is available.
-
-** A reference card for Dired has been added. Its name is
-`dired-ref.tex'. A French translation is available in
-`fr-drdref.tex'.
-
** The new variable `auto-mode-interpreter-regexp' contains a regular
expression matching interpreters, for file mode determination.
regular expression. The mode is then determined as the mode
associated with that interpreter in `interpreter-mode-alist'.
-+++
-** C-down-mouse-3 is bound differently. Now if the menu bar is not
-displayed it pops up a menu containing the items which would be on the
-menu bar. If the menu bar is displayed, it pops up the major mode
-menu or the Edit menu if there is no major mode menu.
-
-** Variable `load-path' is no longer customizable because it contains
-a version-dependent component.

-
-** Item Save Options on the Options menu allows saving options set
-using that menu.
-
** New function executable-make-buffer-file-executable-if-script-p is
suitable as an after-save-hook as an alternative to `executable-chmod'.
** Variable `default-korean-keyboard' is initialized properly from the
environment variable `HANGUL_KEYBOARD_TYPE'.
-+++
-** C-u C-x = provides detailed information about the character at
-point in a pop-up window.
-
+++
** New command M-x list-charset-chars reads a character set name and
displays all characters in that character set.

commenting with the variable `comment-style'.
-+++
-** The function `getenv' is now callable interactively.
-
-** The many obsolete language `setup-...-environment' commands have
-been removed -- use `set-language-environment'.
-
+++
** New user options `display-time-mail-face' and
`display-time-use-mail-icon' control the appearance of mode-line mail
indicator used by the display-time package. On a suitable display the
indicator can be an icon and is mouse-sensitive.
-+++
-** Emacs' auto-save list files are now by default stored in a
-sub-directory `.emacs.d/auto-save-list/' of the user's home directory.
-(On MS-DOS, this subdirectory's name is `_emacs.d/auto-save.list/'.)
-You can customize `auto-save-list-prefix' to change this location.
-
+++
** On window-systems, additional space can be put between text lines
on the display using several methods
** New commands iso-iso2sgml and iso-sgml2iso convert between Latin-1
characters and the corresponding SGML (HTML) entities.
-+++
-** Emacs now refuses to load compiled Lisp files which weren't
-compiled with Emacs. Set `load-dangerous-libraries' to t to change
-this behavior.

-shown, if non-nil a hollow box cursor is shown. This option can
-be customized.
-
+++
** The variable `echo-keystrokes' may now have a floating point value.
-+++
-** C-x 5 1 runs the new command delete-other-frames which deletes
-all frames except the selected one.
-
** If your init file is compiled (.emacs.elc), `user-init-file' is set
to the source name (.emacs.el), if that exists, after loading it.
MS-DOS, either in the echo area or with tooltips. Many standard menus
displayed by Emacs now have help strings.
-+++
-** Highlighting of mouse-sensitive regions is now supported in the
-MS-DOS version of Emacs.
-
** New user option `read-mail-command' specifies a command to use to
read mail from the menu etc.
** Hexl contains a new command `hexl-insert-hex-string' which inserts
a string of hexadecimal numbers read from the mini-buffer.
-+++
-** Just loading the msb package doesn't switch on Msb mode anymore.
-If you have `(require 'msb)' in your .emacs, please replace it with
-`(msb-mode 1)'.
-
** Changes in Texinfo mode.
*** A couple of new key bindings have been added for inserting Texinfo
M-x clone-buffer can also be used on *Help* and several other special
buffers.
-+++
-** Emacs can now support 'wheeled' mice (such as the MS IntelliMouse)
-under XFree86. To enable this, use the `mouse-wheel-mode' command, or
-customize the variable `mouse-wheel-mode'.
-
-The variables `mouse-wheel-follow-mouse' and `mouse-wheel-scroll-amount'
-determine where and by how much buffers are scrolled.
-
** Listing buffers with M-x list-buffers (C-x C-b) now shows
abbreviated file names. Abbreviations can be customized by changing
`directory-abbrev-alist'.
The X resource name of this parameter is `screenGamma', class
`ScreenGamma'.
-** Emacs has a new redisplay engine.
-
-The new redisplay handles characters of variable width and height.
-Italic text can be used without redisplay problems. Fonts containing
-oversized characters, i.e. characters larger than the logical height
-of a font can be used. Images of various formats can be displayed in
-the text.
-
-** Emacs has a new face implementation.
-
-The new faces no longer fundamentally use X font names to specify the
-font. Instead, each face has several independent attributes--family,
-height, width, weight and slant--that it may or may not specify.
-These attributes can be merged from various faces, and then together
-specify a font.
-
-Faces are supported on terminals that can display color or fonts.
-These terminal capabilities are auto-detected. Details can be found
-under Lisp changes, below.
-
-** New default font is Courier 12pt under X.
-
-+++
-** When using a windowing terminal, each Emacs window now has a cursor
-of its own. When the window is selected, the cursor is solid;
-otherwise, it is hollow.
-
-** Bitmap areas to the left and right of windows are used to display
-truncation marks, continuation marks, overlay arrows and alike. The
-foreground, background, and stipple of these areas can be changed by
-customizing face `fringe'.

-** The mode line under X is now drawn with shadows by default.
-You can change its appearance by modifying the face `mode-line'.
-In particular, setting the `:box' attribute to nil turns off the 3D
-appearance of the mode line. (The 3D appearance makes the mode line

-the window to be partially obscured.)
-
-The variable `mode-line-inverse-video', which was used in older
-versions of emacs to make the mode-line stand out, now defaults to nil,
-and its use is deprecated.
-
-** LessTif support.
-
-Emacs now runs with the LessTif toolkit (see
-<http://www.lesstif.org>). You will need version 0.92 or later.
-Please use LessTif's Motif 1.2 emulation; the emulations of Motif 2.0
-and 2.1 are known not to work well with Emacs.
-
-** Toolkit scroll bars.
-
-Emacs now uses toolkit scrollbars if available. When configured for
-LessTif/Motif, it will use that toolkit's scrollbar. Otherwise, when
-configured for Lucid and Athena widgets, it will use the Xaw3d scroll
-bar if Xaw3d is available. You can turn off the use of toolkit scroll
-bars by specifying `--with-toolkit-scroll-bars=no' when configuring
-Emacs.
-
-When you encounter problems with the Xaw3d scroll bar, watch out how
-Xaw3d is compiled on your system. If the Makefile generated from
-Xaw3d's Imakefile contains a `-DNARROWPROTO' compiler option, and your
-Emacs system configuration file `s/your-system.h' does not contain a
-define for NARROWPROTO, you might consider adding it. Take
-`s/freebsd.h' as an example.
-
-Alternatively, if you don't have access to the Xaw3d source code, take
-a look at your system's imake configuration file, for example in the
-directory `/usr/X11R6/lib/X11/config' (paths are different on
-different systems). You will find files `*.cf' there. If your
-system's cf-file contains a line like `#define NeedWidePrototypes NO',
-add a `#define NARROWPROTO' to your Emacs system configuration file.
-
-The reason for this is that one Xaw3d function uses `double' or
-`float' function parameters depending on the setting of NARROWPROTO.
-This is not a problem when Imakefiles are used because each system's
-image configuration file contains the necessary information. Since
-Emacs doesn't use imake, this has do be done manually.
-
-** Toggle buttons and radio buttons in menus.
-
-When compiled with LessTif (or Motif) support, Emacs uses toolkit
-widgets for radio and toggle buttons in menus. When configured for
-Lucid, Emacs draws radio buttons and toggle buttons similar to Motif.
-
-+++
-** Highlighting of trailing whitespace.
-
-When `show-trailing-whitespace' is non-nil, Emacs displays trailing
-whitespace in the face `trailing-whitespace'. Trailing whitespace is
-defined as spaces or tabs at the end of a line. To avoid busy
-highlighting when entering new text, trailing whitespace is not
-displayed if point is at the end of the line containing the
-whitespace.
-
-+++
-** Hourglass pointer
-
-Emacs can optionally display an hourglass pointer under X. You can
-turn the display on or off by customizing group `cursor'.
-
-+++
-** Blinking cursor
-
-M-x blink-cursor-mode toggles a blinking cursor under X and on
-terminals having terminal capabilities `vi', `vs', and `ve'. Blinking
-and related parameters like frequency and delay can be customized in
-the group `cursor'.
-
-+++
-** New font-lock support mode `jit-lock-mode'.
-
-This support mode is roughly equivalent to `lazy-lock' but is
-generally faster. It supports stealth and deferred fontification.
-See the documentation of the function `jit-lock-mode' for more
-details.
-
-Font-lock uses jit-lock-mode as default support mode, so you don't
-have to do anything to activate it.
-
** Tabs and variable-width text.
Tabs are now displayed with stretch properties; the width of a tab is
*** Arrows that indicate sub-menus are now drawn with shadows, as in
LessTif and Motif.
-+++
-** Hscrolling in C code.
-
-Horizontal scrolling now happens automatically if
-`automatic-hscrolling' is set (the default). This setting can be
-customized.
-
-If a window is scrolled horizontally with set-window-hscroll, or
-scroll-left/scroll-right (C-x <, C-x >), this serves as a lower bound
-for automatic horizontal scrolling. Automatic scrolling will scroll
-the text more to the left if necessary, but won't scroll the text more
-to the right than the column set with set-window-hscroll etc.

-** Tool bar support.
-
-Emacs supports a tool bar at the top of a frame under X. For details
-of how to define a tool bar, see the page describing Lisp-level
-changes. Tool-bar global minor mode controls whether or not it is
-displayed and is on by default. The appearance of the bar is improved
-if Emacs has been built with XPM image support. Otherwise monochrome
-icons will be used.
-
-To make the tool bar more useful, we need contributions of extra icons
-for specific modes (with copyright assignments). Contributions would
-also be useful manually to touch up some of the PBM icons.
-
-+++
-** Mouse-sensitive mode line.
-
-Different parts of the mode line under X have been made
-mouse-sensitive. Moving the mouse to a mouse-sensitive part in the mode
-line changes the appearance of the mouse pointer to an arrow, and help
-about available mouse actions is displayed either in the echo area, or
-in the tooltip window if you have enabled one.
-
-Currently, the following actions have been defined:
-
-- Mouse-1 on the buffer name in the mode line switches between two
-buffers.
-
-- Mouse-2 on the buffer-name switches to the next buffer, and
-M-mouse-2 switches to the previous buffer in the buffer list.
-
-- Mouse-3 on the buffer-name displays a buffer menu.
-
-- Mouse-2 on the read-only or modified status in the mode line (`%' or
-`*') toggles the status.
-
-- Mouse-3 on the mode name displays a minor-mode menu.
-
-** LessTif/Motif file selection dialog.
-
-When Emacs is configured to use LessTif or Motif, reading a file name
-from a menu will pop up a file selection dialog if `use-dialog-box' is
-non-nil.
-
-** Emacs can display faces on TTY frames.
-
-Emacs automatically detects terminals that are able to display colors.
-Faces with a weight greater than normal are displayed extra-bright, if
-the terminal supports it. Faces with a weight less than normal and
-italic faces are displayed dimmed, if the terminal supports it.
-Underlined faces are displayed underlined if possible. Other face
-attributes such as `overline', `strike-through', and `box' are ignored
-on terminals.
-
-The command-line options `-fg COLOR', `-bg COLOR', and `-rv' are now
-supported on character terminals.
-
** Sound support
Emacs supports playing sound files on GNU/Linux and FreeBSD (Voxware
you complete mail aliases in the text, analogous to
lisp-complete-symbol.
-+++
-** Emacs now resizes mini-windows if appropriate.
-
-If a message is longer than one line, or minibuffer contents are
-longer than one line, Emacs can resize the minibuffer window unless it
-is on a frame of its own. You can control resizing and the maximum
-minibuffer window size by setting the following variables:
-
-- User option: max-mini-window-height
-
-Maximum height for resizing mini-windows. If a float, it specifies a
-fraction of the mini-window frame's height. If an integer, it
-specifies a number of lines.
-
-Default is 0.25.
-
-- User option: resize-mini-windows
-
-How to resize mini-windows. If nil, don't resize. If t, always
-resize to fit the size of the text. If `grow-only', let mini-windows
-grow only, until they become empty, at which point they are shrunk
-again.
-
-Default is `grow-only'.
-
** The command `Info-search' now uses a search history.
** Changes to hideshow.el
** Partial Completion mode now completes environment variables in
file names.
-+++
-** Tooltips.
-
-Tooltips are small X windows displaying a help string at the current
-mouse position. The Lisp package `tooltip' implements them. You can
-turn them off via the user option `tooltip-mode'.
-
-Tooltips also provides support for GUD debugging. If activated,
-variable values can be displayed in tooltips by pointing at them with
-the mouse in source buffers. You can customize various aspects of the
-tooltip display in the group `tooltip'.

** Customize changes
*** An "alignment error" bug was fixed when a manual spelling
correction is made and re-checked.
-*** An Italian and a Portuguese dictionary definition has been added.
+*** An Italian, Portuguese, and Slovak dictionary definition has been added.
*** Region skipping performance has been vastly improved in some
cases.
"dir/sub", "tempfile", "tempfile.c". If the tag matches the file name,
point will go to the beginning of the file.

+*** Compressed files are now transparently supported if
auto-compression-mode is active. You can tag (with Etags) and search
(with find-tag) both compressed and uncompressed files.
+*** Tags commands like M-x tags-search no longer change point
+in buffers where no match is found. In buffers where a match is
+found, the original value of point is pushed on the marker ring.
