It is no longer needed, as the crt*.o files are no longer linked
specially.
** Directories passed to configure option `--enable-locallisppath' are
no longer created during installation.

-(which it normally is on most systems), the function
-`zlib-decompress-region' becomes available, which can decompress gzip-
-and zlib-format compressed data.

----
-** The option `set-mark-default-inactive' has been deleted.
-This unfinished feature was introduced by accident in Emacs 23.1;

+---
+*** `split-window' is now a non-interactive function, not a command.
+As a command, it was a special case of `C-x 2' (`split-window-below'),
+and as such superfluous. After being reimplemented in Lisp, its

+using the scroll bar (i.e. dragging the thumb down even when the end
+of the buffer is visible).

+\f
+* Editing Changes in Emacs 24.4
+
+** Indentation changes
+
++++
+*** The behavior of `C-x TAB' (`indent-rigidly') has changed.
+When invoked without a prefix argument, it now activates a transient
+mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts
+the text indentation in the region. Typing any other key resumes
+normal editing behavior.
+
++++
+*** `electric-indent-mode' is enabled by default.
-** `tab-stop-list' is now implicitly extended to infinity by repeating
+*** `tab-stop-list' is now implicitly extended to infinity by repeating
the last step. Its default value is changed to nil which means a tab
stop every `tab-width' columns.
----
-** `split-window' is no longer a command, just a non-interactive function.
-As a command it was a special case of `split-window-below', and as such
-superfluous. After being reimplemented in Lisp, its interactive form

-bound to <f11> and M-<f10>, respectively.
+*** New command `cycle-spacing' cycles between spacing conventions:
+having just one space, no spaces, or reverting to the original
+spacing. Like `just-one-space', it can handle or ignore newlines and
+leave different number of spaces.
+

-You can pick the name of the function and the variables with `C-x 4 a'.
+*** New command `C-x r f' (`frameset-to-register').
+See Changes in Emacs 24.4, above.
+
+** New command `delete-duplicate-lines'.
+When its arg ADJACENT is non-nil (when called interactively with C-u
+C-u) it works like the utility `uniq'. Otherwise by default it
+deletes duplicate lines everywhere in the region without regard to
+adjacency. When its arg KEEP-BLANKS is non-nil (when called
+interactively with C-u C-u C-u), duplicate blank lines are preserved.

* Changes in Specialized Modes and Packages in Emacs 24.4
-** CUA-mode
-*** CUA-mode was changed to make use of delete-selection-mode and
-shift-select-mode. So you can now enable it independently from
-transient-mark-mode, delete-selection-mode, and shift-select-mode.
-As a result, cua-highlight-region-shift-only is obsolete
-(you can disable transient-mark-mode to get the same result).
-*** CUA's rectangles can now be used via `cua-rectangle-mark-mode'.
-
-** `delete-selection-mode' can be used without transient-mark-mode.
-
-** prolog-use-smie has been removed, along with the non-SMIE indentation code.
-
-** SMIE indentation can be customized via `smie-config'.
-The customization can be guessed by Emacs by providing a sample indented
-file and letting SMIE learn from it.
-
-** sh-script now uses its SMIE indentation algorithm by default.
-
-** If your Emacs is compiled with libxml2 support, you can use the new
-built-in web browser `eww'.
-
-** `remember' can now store notes in separates files
-You can use the new function `remember-store-in-files' within the
-`remember-handler-functions' option.
-
-See `remember-data-directory' and `remember-directory-file-name-format'
-for new options related to this function.
-
** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.
Affected files:
~/.emacs.d/timelog replaces ~/.timelog
~/.emacs.d/todo-done replaces ~/.todo-done
~/.emacs.d/todo-top replaces ~/.todo-top
+** Backtrace and debugger
-** Delphi mode is now called OPascal mode.

-
-** jit-lock-debug-mode lets you use the debuggers on code run via jit-lock.
-
-** Minibuffer
-
-*** completing-read-multiple's separator can now be a regexp.
-The default separator is changed to allow surrounding spaces around the comma.
+*** The Lisp debugger's `e' command now includes the lexical environment
+when evaluating the code in the context at point. Hence, it now lets
+you access lexical variables.
-*** New option `read-regexp-defaults-function' defines the function
-that provides the default value for commands that ask for a regexp:
-`rgrep', `lgrep' `occur', `multi-occur', `multi-occur-in-matching-buffers',
-`highlight-regexp', `highlight-lines-matching-regexp', `highlight-phrase'.
-This option can be customized to values that provide a default value
-from the regexp last history element or from the symbol found at point.
+*** New command `v' (`debuger-toggle-locals) displays local vars.
-** The backtrace debugger and local variables:
-*** The debugger's `e' command evaluates the code in the context at point.
-This includes using the lexical environment at point, which means that
-`e' now lets you access lexical variables as well.
-*** The backtrace debugger can display local vars with `v'.
+*** New minor mode `jit-lock-debug-mode' lets you use the debuggers on
+code run via JIT Lock.

+++
*** New variable `diary-from-outlook-function', used by the command
`diary-from-outlook'.
-** VC and related modes
-
-*** In VC directory mode, `D' displays diffs between VC-controlled
-whole tree revisions.
-
-*** In VC directory mode, `L' lists the change log for the current VC
-controlled tree in a window.
-
-*** In VC directory mode, `I' shows a log of changes that will be
-received with a pull operation.
-
-*** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file
-under current version control system. When called with a prefix
-argument, you can remove a file from the ignored file list.
-
-*** `cvs-append-to-ignore' has been renamed to `vc-cvs-append-to-ignore'
-because it is moved to vc-cvs.el.
-
-** cl-lib
-
-*** New macro cl-tagbody.
-

+**** Improved detection of used namespaces in current scope in C++.
+
+**** Parsing of default values for variables and function arguments in C/C++.
+They are also displayed by the summarize feature in the modeline.
+
+**** Improved parsing of function pointers in C/C++.
+This also includes parsing of function pointers as function arguments.
+
+**** Parsing of C/C++ preprocessor macros which open new scope.
+For example, this enables parsing of macros which open new namespaces.
+
+**** Support for 'this' pointer in inline member functions in C++.
+
+** cl-lib
+
+*** New macro cl-tagbody.
+
++++
+*** letf is now just an alias for cl-letf.
+
+** CUA mode
+
+*** CUA mode was changed to make use of delete-selection-mode and
+shift-select-mode. So you can now enable it independently from
+transient-mark-mode, delete-selection-mode, and shift-select-mode.
+As a result, cua-highlight-region-shift-only is obsolete
+(you can disable transient-mark-mode to get the same result).
+
+*** CUA's rectangles can now be used via `cua-rectangle-mark-mode'.
+

+*** New macro `skip-unless' allows skipping ERT tests.
+See the ERT manual for details.
+
+** Eshell
+
++++
+*** `eshell' now supports visual subcommands and options
+Eshell has been able to handle "visual" commands (interactive,
+non-line oriented commands such as top that require display
+capabilities not provided by eshell) by running them in an Emacs
+terminal emulator. See `eshell-visual-commands'.
+
+This feature has been extended to subcommands and options that make a
+usually line-oriented command a visual command. Typical examples are
+"git log" and "git <command> --help" which display their output in a
+pager by default. See `eshell-visual-subcommands' and
+`eshell-visual-options'.
+
+---
+*** Added Eshell-Tramp module
+External su and sudo commands are now the default; the internal,
+Tramp-using variants can still be used by enabling the eshell-tramp
+module.
+
+** F90 mode
+---
+*** New option `f90-smart-end-names'.

+
+** Image mode
+
+*** New commands `n' (`image-next-file') and `p' (`image-previous-file')
+visit the next image file and the previous image file in the same
+directory, respectively.
+
+*** New commands to show specific frames of multi-frame images.
+`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
+next or previous frame. `F' (`image-goto-frame') shows a specific frame.
+
+*** New commands to speed up, slow down, or reverse animation.
+---
+*** The command `image-mode-fit-frame' deletes other windows.
+When toggling, it restores the frame's previous window configuration.
+It also has an optional frame argument, which can be used by Lisp
+callers to fit the image to a frame other than the selected frame.
+
+** Hi-Lock
+
+*** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands
+will cycle through faces in `hi-lock-face-defaults' without prompting.

+comprehensions.
+
+*** New option `js-switch-indent-offset`.
+
+** MH-E has been updated to MH-E version 8.5.
+See MH-E-NEWS for details.

+** Octave mode
+*** Font locking for texinfo comments and new keywords
+*** Completion in Octave file buffers
+*** Eldoc support
+*** Jump to definition

-*** `ido-use-virtual-buffers' takes a new value 'auto.
-*** `ido-decorations' has been slightly extended to give a bit more control.
+You may think of it as a *scratch* buffer whose content is preserved.
+In fact, it was designed as a replacement for *scratch* buffer and can
+be used that way by setting `initial-buffer-choice' to

-*** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands
-will cycle through faces in `hi-lock-face-defaults' without prompting.
+*** New mode menu.
-+++
-*** New global command `M-s h .' (`highlight-symbol-at-point')
-highlights the symbol found near point without prompting,
-using the next face automatically.
+*** Improved syntax highlighting and indentation.
+
+*** Add more Ruby file types to `auto-mode-alist'.
+
+*** New option `ruby-align-to-stmt-keywords'.
** Search and Replace
The same rules are now applied to the symbol search with the difference
that it matches symbols, and non-symbol characters between symbols.
-** MH-E has been updated to MH-E version 8.5.
-See MH-E-NEWS for details.
++++
+** SES
----
-** The unrmail command converts from BABYL to mboxrd rather than mboxo.
-Customize `unrmail-mbox-format' to change this.
+*** New command `ses-rename-cell' allows assigning names to SES cells.
----
-** Similarly, customize `rmail-mbox-format' to influence some minor aspects
-of how Rmail displays non-MIME messages.
+** Shell
-+++
-** New function `ses-rename-cell' to give SES cells arbitrary names.
+*** `explicit-bash-args' now always defaults to use --noediting.
+During initialization, Emacs no longer expends a process to decide
+whether it is safe to use Bash's --noediting option. These days
+--noediting is ubiquitous; it was introduced in 1996 in Bash version 2.
-** trace-function was largely rewritten.
-New features include:
-- no prompting for the destination buffer, unless a prefix-arg was used.
-- additionally to prompting for a destination buffer, when a prefix-arg is
- used, the user can enter a "context", i.e. Lisp expression whose value at the
- time the function is entered/exited will be printed along with the function
- name and arguments. Useful to trace the value of (current-buffer) or
- (point) when the function is invoked.
+*** The SMIE indentation engine is now used by default.
-** New command `delete-duplicate-lines' has new types of operation:
-When its arg ADJACENT is non-nil (when called interactively with C-u C-u)
-it works like the utility `uniq'. Otherwise by default it deletes
-duplicate lines everywhere in the region without regard to adjacency.
-When its arg KEEP-BLANKS is non-nil (when called interactively with
-C-u C-u C-u), duplicate blank lines are preserved.
+** Shell Script mode
-** New `cycle-spacing' command allows cycling between having just one
-space, no spaces, or reverting to the original spacing. Like
-`just-one-space' command it can handle or ignore newlines and
-leave different number of spaces.
+*** `sh-mode' now has the mode own `add-log-current-defun-function'.
+You can pick the name of the function and the variables with `C-x 4 a'.
+
+** SMIE indentation can be customized via `smie-config'.
+The customization can be guessed by Emacs by providing a sample indented
+file and letting SMIE learn from it.
+
+** Term mode
+
+*** New option `term-suppress-hard-newline'.
** Todo mode has been rewritten and enhanced.
New features include:
later time with the provided conversion command. The old version of
todo-mode.el has been made obsolete and renamed otodo-mode.el.
+** trace-function was largely rewritten.
+New features include:
+- no prompting for the destination buffer, unless a prefix-arg was used.

-** Eshell
-
-+++
-*** `eshell' now supports visual subcommands and options
-Eshell has been able to handle "visual" commands (interactive,
-non-line oriented commands such as top that require display
-capabilities not provided by eshell) by running them in an Emacs
-terminal emulator. See `eshell-visual-commands'.
-
-This feature has been extended to subcommands and options that make a
-usually line-oriented command a visual command. Typical examples are
-"git log" and "git <command> --help" which display their output in a
-pager by default. See `eshell-visual-subcommands' and
-`eshell-visual-options'.
-
----
-*** Added Eshell-Tramp module
-External su and sudo commands are now the default; the internal,
-Tramp-using variants can still be used by enabling the eshell-tramp
-module.
-
-** Package
-
-*** The format of `archive-contents' files, generated by package
-repositories, has changed to allow a new (fifth) element in the data
-vectors, containing an associative list with extra properties.
-
-*** `describe-package' buffer uses the `:url' extra property to
-display a `Homepage' header, if it's present.
-
-** New term.el option `term-suppress-hard-newline'.
+** VC and related modes
-** CEDET
+*** In VC directory mode, `D' displays diffs between VC-controlled
+whole tree revisions.
-*** EDE
+*** In VC directory mode, `L' lists the change log for the current VC
+controlled tree in a window.
-**** The cpp-root project now supports executing a compile command.
-It can be set through the new :compile-command slot or the
-buffer-local variable `compile-command'.
+*** In VC directory mode, `I' shows a log of changes that will be
+received with a pull operation.
-**** Better selection of include directories for the 'linux' project.
-Include directories now support out-of-tree build directories and
-target architecture auto-detection.
+*** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file
+under current version control system. When called with a prefix
+argument, you can remove a file from the ignored file list.
-*** Semantic
+*** `cvs-append-to-ignore' has been renamed to `vc-cvs-append-to-ignore'
+because it is moved to vc-cvs.el.
-**** Improved detection of used namespaces in current scope in C++.
+** VHDL mode
-**** Parsing of default values for variables and function arguments in C/C++.
-They are also displayed by the summarize feature in the modeline.
+*** New options: `vhdl-actual-generic-name', `vhdl-beautify-options'.
-**** Improved parsing of function pointers in C/C++.
-This also includes parsing of function pointers as function arguments.
+*** New commands: `vhdl-fix-statement-region', `vhdl-fix-statement-buffer'.
-**** Parsing of C/C++ preprocessor macros which open new scope.
-For example, this enables parsing of macros which open new namespaces.
+** Woman
-**** Support for 'this' pointer in inline member functions in C++.
+*** The commands `woman-default-faces' and `woman-monochrome-faces'
+are obsolete. Customize the `woman-*' faces instead.
** Obsolete packages:

* New Modes and Packages in Emacs 24.4
-** New `superword-mode' in subword.el
+** New package `eww' is a built-in web browser.
+It is only available if Emacs is compiled with libxml2 support.
+
+** New minor mode `superword-mode', defined in subword.el
`superword-mode' overrides the default word motion commands to treat
symbol_words as a single word, similar to what `subword-mode' does and
using the same internal functions.
-** New nadvice.el package offering lighter-weight advice facilities.
+** New package nadvice.el offers lighter-weight advice facilities.
It is layered as:
- add-function/remove-function which can be used to add/remove code on any
function-carrying place, such as process-filters or `<foo>-function' hooks.
- advice-add/advice-remove to add/remove a piece of advice on a named function,
much like `defadvice' does.
-** New frameset.el package.
+** New package frameset.el.
It provides a set of operations to save a frameset (the state of all
or a subset of the existing frames and windows, somewhat similar to a
frame configuration), both in-session and persistently, and restore it
at some point in the future.

+notifications. It requires that Emacs be compiled with one of the
low-level libraries gfilenotify.c, inotify.c or w32notify.c.
\f
** The syntax of ?» and ?« is now punctuation instead of matched parens.
Some languages match those as »...« and others as «...» so better stay neutral.
+** In compiled Lisp files, the header no longer includes a timestamp.
+
** The default file coding for Emacs Lisp files is now utf-8.
-(See file-coding-system-alist.) In most cases, this change is transparent, but
-files that contain unusual characters without specifying an explicit coding
-system may fail to load with obscure errors.
-You should either convert them to utf-8 or add an explicit `coding:' cookie.

-** overriding-terminal-local-map does not replace the local keymaps any more.
+** `overriding-terminal-local-map' no longer replaces the local keymaps.
It used to disable the minor mode, major mode, and text-property keymaps,
whereas now it simply has higher precedence.
\f
* Lisp Changes in Emacs 24.4
+** New variable `enable-dir-local-variables'.
+Directory-local variables are ignored if this is set to nil. This may
+be useful for modes that want to ignore directory-locals while still
+respecting file-local variables.
+
+** New macro `define-alternatives' can be used to define generic commands.
+Generic commands are interactive functions whose implementation can be
+selected among several alternatives, as a matter of user preference.
+
+** New function `get-pos-property'.
+
+** Minibuffer changes
+
+*** completing-read-multiple's separator can now be a regexp.
+The default separator is changed to allow surrounding spaces around the comma.
+
+*** New option `read-regexp-defaults-function' defines the function
+that provides the default value for commands that ask for a regexp:
+`rgrep', `lgrep' `occur', `multi-occur', `multi-occur-in-matching-buffers',
+`highlight-regexp', `highlight-lines-matching-regexp', `highlight-phrase'.
+This option can be customized to values that provide a default value
+from the regexp last history element or from the symbol found at point.
+
** New option `load-prefer-newer', if non-nil, means that when both
.el and .elc versions of a file exist, rather than `load' always
choosing the .elc version, it will choose whichever is newer
(unless you explicitly specify one or the other).
-** New function get-pos-property.
-
** New hook `pre-redisplay-function'.
+++
** `get-upcase-table' is obsoleted by the new `case-table-get-table'.
-** Support for filesystem notifications.
+** File-handling changes
+
+*** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files. This requires the
`glib' API, or the 'inotify' API (on GNU/Linux systems only). On
MS-Windows systems, this is supported for Windows XP and newer
versions.
+*** The 9th element returned by `file-attributes' is now unspecified.
+Formerly, it was t if the file's gid would change if file were deleted
+and recreated. This value has been inaccurate for years on many
+platforms, and nobody seems to have noticed or cared.
+
+*** The 6th argument to `copy-file' has been renamed to
+PRESERVE-EXTENDED-ATTRIBUTES as it now handles both SELinux context
+and ACL entries.
+
+*** The function `file-ownership-preserved-p' now has an optional
+argument GROUP which causes it check for file group too. This can be
+used in place of the 9th element of `file-attributes'.
+
+
+*** The function `set-visited-file-modtime' now accepts a 0 or -1
+argument, with the same interpretation as the returned value of
+`visited-file-modtime'.
+
** Changes in autorevert.el
---
set (defface, custom, or user spec), and it directly sets the relevant
property using the supplied face spec.
+*** New function `add-face-text-property', which can be used to
+conveniently prepend/append new face properties.
+
*** Face specs set via Custom themes now replace the `defface' spec
rather than inheriting from it (as do face specs set via Customize).

`coding-system-type' function.)
-** The function `set-visited-file-modtime' now accepts a 0 or -1 argument
-with the same interpretation as the returned value of `visited-file-modtime'.
+** `time-to-seconds' is not obsolete any more.
+
+** New functions `special-form-p' and `macrop'.
-** time-to-seconds is not obsolete any more.
-** New functions special-form-p and macrop.
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
text-property on the first char.
On file systems that do not support symbolic links, the lock is now a
regular file with contents being what would have been in the symlink.
-** The 9th element returned by `file-attributes' is now unspecified.
-Formerly, it was t if the file's gid would change if file were deleted
-and recreated. This value has been inaccurate for years on many
-platforms, and nobody seems to have noticed or cared.
-
-** The function `file-ownership-preserved-p' now has an optional
-argument GROUP which causes it check for file group too. This can be
-used in place of the 9th element of `file-attributes'.
-
** New functions `group-gid' and `group-real-gid'.
-** The 6th argument to `copy-file' has been renamed to
-`preserve-extended-attributes' as it now handles both SELinux context
-and ACL entries.
-
** The `common-substring' argument of display-completion-list is obsolete.
Either use `completion-all-completions' which already returns highlighted
strings (including for partial or substring completion) or call
