* Installation Changes in Emacs 24.4
+
+** Emacs can be compiled with POSIX ACL support.
+This happens by default if a suitable support library is found at
+build time, like libacl on GNU/Linux. To prevent this, use the
+configure option `--without-acl'.
+
* Startup Changes in Emacs 24.4
* Changes in Emacs 24.4
++++
+** `apropos-variable' is now `apropos-user-option'
+`apropos-user-option' shows all user options while `apropos-variable'
+shows all variables. When called with a universal prefix argument,
+the two commands swap their behaviors. When `apropos-do-all' is
+non-nil, they output the same results.
+
+++
** `eval-defun' on an already defined defcustom calls the :set function,
if there is one.
This unfinished feature was introduced by accident in Emacs 23.1;
simply disabling Transient Mark mode does the same thing.
+** `initial-buffer-choice' can now specify a function to set up the
+initial buffer.
+
+** ACL support has been added.
++++
+*** Emacs preserves the ACL entries of files when backing up.
++++
+*** New functions `file-acl' and `set-file-acl' get and set the ACL
+entries of a file. On GNU/Linux, the POSIX ACL interface is used via
+libacl. On MS-Windows, the NT Security APIs are used to emulate the
+POSIX ACL interfaces.
+
* Editing Changes in Emacs 24.4
+** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
+bound to <f11> and M-<f10>, respectively.
+
\f
* Changes in Specialized Modes and Packages in Emacs 24.4
-** New macro cl-tagbody in cl-lib.
+** Battery
+
+*** Battery information via the BSD `apm' utility is now supported.
+
+** cl-lib
+
+*** New macro cl-tagbody.
+
++++
+*** letf is now just an alias for cl-letf.
+
** Calc
*** Calc by default now uses the Gregorian calendar for all dates, and
*** The icomplete-separator is customizable, and its default has changed.
*** Removed icomplete-show-key-bindings.
+** Isearch
+
+*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
+and adds it to the search string.
+
** MH-E has been updated to MH-E version 8.4.
See MH-E-NEWS for details.
*** New connection method "adb", which allows to access Android
devices by the Android Debug Bridge. The variable `tramp-adb-sdk-dir'
must be set to the Android SDK installation directory.
++++
+*** Handlers for `file-acl' and `set-file-acl' for remote machines
+which support POSIX ACLs.
** Woman
* Incompatible Lisp Changes in Emacs 24.4
+** frame-local variables that affect redisplay do not work any more.
+More specifically, the redisplay does not bother to check for a frame-local
+value when looking up variables.
+
** nil and "unbound" are indistinguishable in symbol-function.
`symbol-function' never signals `void-function' any more.
`fboundp' returns non-nil if the symbol was `fset' to nil.
VAR was bound to nil which was not tremendously useful and just lead to
spurious warnings about an unused var.
+** The return value of `backup-buffer' has changed.
+The second argument is no longer an SELinux context, instead it is an
+alist of extended attributes as returned by the new function
+`file-extended-attributes'. The attributes can be applied to another
+file using `set-file-extended-attributes'.
+
* Lisp changes in Emacs 24.4
** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files. This requires the
-'inotify' API on GNU/Linux systems.
+'inotify' API on GNU/Linux systems. On MS-Windows systems, this is
+supported for Windows XP and newer versions.
** Face changes
*** Face specs set via Custom themes now replace the `defface' spec
rather than inheriting from it (as do face specs set via Customize).
+*** New face characteristic (supports :underline (:style wave))
+specifies whether or not the terminal can display a wavy line.
+
** time-to-seconds is not obsolete any more.
** New function special-form-p.
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
** The `defalias-fset-function' property lets you catch calls to defalias
and redirect them to your own function instead of `fset'.
+** 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.
+

* Installation Changes in Emacs 24.3
----
-** The default toolkit has been changed to Gtk+ version 3.
-If you don't pass --with-x-toolkit to configure or if you pass
---with-x-toolkit=gtk or --with-x-toolkit=yes, configure will try to build
-with Gtk+ version 3, and if that fails, try Gtk+ version 2.
+** The default X toolkit is now Gtk+ version 3.
+If you don't pass `--with-x-toolkit' to configure, or if you use
+`--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try
+to build with Gtk+ version 3, and if that fails, try Gtk+ version 2.
You can explicitly require a specific version by passing
---with-x-toolkit=gtk2 or --with-x-toolkit=gtk3 to configure.
+`--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure.
----
-** New configure option '--without-all' to disable additional features.
-This disables most of the features that are normally enabled by default.
-
----
-** New configure option '--enable-link-time-optimization' to utilize
+** New configure option `--enable-link-time-optimization', to utilize
an appropriate feature provided by GCC since version 4.5.0.
----
-** New configure option '--enable-gcc-warnings', intended for developers.
-If building with GCC, this enables compile-time checks that warn about
-possibly-questionable C code. On a recent GNU system there should be
-no warnings; on older and on non-GNU systems the generated warnings
-may be useful.
+** New configure option `--without-all' to disable most of the optional
+features (image support, etc.) that are normally enabled by default.
----
-** The configure option '--enable-use-lisp-union-type' has been
-renamed to '--enable-check-lisp-object-type', as the resulting
+** New configure option `--enable-gcc-warnings' (for developing/debugging
+Emacs). If building with GCC, this enables compile-time checks that
+warn about possibly-questionable C code. On a recent GNU system there
+should be no warnings; on older and on non-GNU systems the generated
+warnings may be useful.
+
+** The configure option `--enable-use-lisp-union-type' has been
+renamed to `--enable-check-lisp-object-type', as the resulting
Lisp_Object type no longer uses a union to implement the compile time
check that this option enables.
----
-** The configure option '--disable-maintainer-mode' has been removed,
+** The configure option `--disable-maintainer-mode' has been removed,
as it was confusingly-named and rarely useful.
----
-** You can use `NO_BIN_LINK=t make install' to prevent the installation
-overwriting "emacs" in the installation bin/ directory with a link
-to emacs-VERSION.
-
----
** The configure options `--program-prefix', `--program-suffix', and
`--program-transform-name' apply to more than just the installed
binaries. Now they also affect the man pages, icons, and the
etc/emacs.desktop file; but not the info pages, since this would break
links between the various manuals.
----
+** You can use `NO_BIN_LINK=t make install' to prevent the installation
+overwriting "emacs" in the installation bin/ directory with a link
+to "emacs-VERSION".
+
** Emacs uses libtinfo in preference to libncurses, if available.
----
** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
/usr/pkg/lib to the linker search path. You must add them yourself if
you want them.
----
-** The standalone scripts rcs-checkin and vcdiff have been removed
+** The standalone scripts `rcs-checkin' and `vcdiff' have been removed
(from the bin and libexec directories, respectively). The former is
no longer relevant, the latter is replaced by lisp (in vc-sccs.el).

-(shown in a tooltip or in the echo area) for any part of the mode line
-that does not have its own specialized help text.
-+++
-*** You can now click mouse-3 in the coding system indicator to invoke
-`set-buffer-file-coding-system'.
+** Help
-** Help changes
-
-+++
-*** `C-h f' (describe-function) can now perform autoloading.
+*** `C-h f' (`describe-function') can now perform autoloading.
When this command is called for an autoloaded function whose docstring
contains a key substitution construct, that function's library is
automatically loaded, so that the documentation can be shown
correctly. To disable this, set `help-enable-auto-load' to nil.
----
*** `C-h f' now reports previously-autoloaded functions as "autoloaded",
even after their associated libraries have been loaded (and the
autoloads have been redefined as functions).
-** Minibuffer changes
----
-*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
-next and previous path separator, respectively.
-+++

-Just set minibuffer-eldef-shorten-default to t before enabling the mode.
+** ImageMagick
-+++
-** ImageMagick support, if available, is automatically enabled.
+*** Images displayed via ImageMagick now support transparency and the
+:background image specification property.
+
+*** When available, ImageMagick support is automatically enabled.
It is no longer necessary to call `imagemagick-register-types'
explicitly to install ImageMagick image types; that function is called
automatically at startup, or when customizing an imagemagick- option.
-+++
+
*** Setting `imagemagick-types-inhibit' to t now disables the use of
-ImageMagick to view images. You must call imagemagick-register-types
-afterwards if you do not use customize to change this.
-+++
+ImageMagick to view images. (You must call `imagemagick-register-types'
+afterwards if you do not use customize to change this.)
+
*** The new variable `imagemagick-enabled-types' also affects which
ImageMagick types are treated as images. The function
`imagemagick-filter-types' returns the list of types that will be
treated as images.
----
-*** Images displayed via ImageMagick now support transparency and the
-:background image spec property.
-** Server and client changes
-+++
+** Minibuffer
+
+*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
+next and previous path separator, respectively.

On encountering a fatal error, Emacs now outputs a textual description
of the fatal signal, and a short backtrace on platforms like glibc
that support backtraces.
----
+** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
+This minor mode replaces `toggle-read-only', which is now obsolete.

`emacs-bzr-version' contains information about the bzr revision used.
-+++
-** New variable `create-lockfiles' specifies usage of lockfiles.
+** New option `create-lockfiles' specifies usage of lockfiles.
It defaults to t. Changing it to nil inhibits the creation of lock
files (use this with caution).
-+++
-** Using "unibyte: t" in Lisp source files is obsolete.
-Use "coding: raw-text" instead.
-
-+++
-** Setting `enable-remote-dir-locals' to non-nil allows directory
-local variables on remote hosts.
+** New option `enable-remote-dir-locals', if non-nil, allows directory-local
+variables on remote hosts.
----
** The entry for PCL-CVS has been removed from the Tools menu.
The PCL-CVS commands are still available via the keyboard.

-+++
-*** New binding `M-g c' for `goto-char'.
-+++
-*** New binding `M-g TAB' for `move-to-column'.
-+++
-*** `M-g TAB' (`move-to-column') prompts for a column number if called
-interactively with no prefix arg. Previously, it moved to column 1.

-** Search and Replace changes
-+++
*** Non-regexp Isearch now performs "lax" space matching.
Each sequence of spaces in the supplied search string may match any
sequence of one or more whitespace characters, as specified by the
variable `search-whitespace-regexp'. (This variable is also used by a
-similar existing feature for regexp Isearch).

+similar existing feature for regexp Isearch.)
+
*** New Isearch command `M-s SPC' toggles lax space matching.
This applies to both ordinary and regexp Isearch.
-+++
+
*** New option `replace-lax-whitespace'.
If non-nil, `query-replace' uses flexible whitespace matching too.
The default is nil.
-+++
+
*** Global `M-s _' starts a symbol (identifier) incremental search,
and `M-s _' in Isearch toggles symbol search mode.
`M-s c' in Isearch toggles search case-sensitivity.
-+++
-** `C-x 8 RET' is now bound to `insert-char', which is now a command.
-`ucs-insert' is now an obsolete alias for `insert-char'.

+
+*** `M-g TAB' (`move-to-column') prompts for a column number if called
+interactively with no prefix arg. Previously, it moved to column 1.
+
+** New option `yank-handled-properties' allows processing of text
+properties on yanked text, in ways that are more general than just
+removing them (as is done by `yank-excluded-properties').
-+++
** New option `delete-trailing-lines' specifies whether
M-x delete-trailing-whitespace should delete trailing lines at the end
of the buffer. It defaults to t.
-** Register changes
-+++
-*** `C-x r +' is now overloaded to invoke `append-to-register.
-+++

----
-*** The faces used by Apropos are now directly customizable.
-These faces are named `apropos-symbol', `apropos-keybinding', and so on;
-see the `apropos' Custom group for details.
----
-*** The old options whose values specified faces to use were removed
-(i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.).

+It copies the region-rectangle as the last rectangle kill.
-** Calendar
+** Registers
-+++
-*** You can customize the header text that appears above each calendar month.
-See the variable `calendar-month-header'.

+\f
+* Changes in Specialized Modes and Packages in Emacs 24.3
-** CL
+** Common Lisp emulation (CL)
-+++
*** CL's main entry is now (require 'cl-lib).
-`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
-i.e. all its definitions have the "cl-" prefix (and internal definitions use
-the "cl--" prefix).

+provide the old, non-prefixed names. Some exceptions are listed below:
-+++
*** `cl-flet' is not like `flet' (which is deprecated).
Instead it obeys the behavior of Common-Lisp's `flet'.
In particular, in cl-flet function definitions are lexically scoped,
whereas in flet the scoping is dynamic.
-+++
*** `cl-labels' is slightly different from `labels'.
-The difference is that it relies on the `lexical-binding' machinery (as opposed
-to the `lexical-let' machinery used previously) to capture definitions in
-closures, so such closures will only work if `lexical-binding' is in use.

*** `cl-letf' is not exactly like `letf'.
The only difference is in details that relate to some deprecated usage
of `symbol-function' in place forms.
-+++
*** `progv' was rewritten to use the `let' machinery.
-A side effect is that vars without corresponding value are bound to nil
-rather than making them unbound.

*** The following methods of extending `setf' are obsolete
(use features from gv.el instead):
`define-modify-macro' (use `gv-letplace')
`define-setf-expander' (use `gv-define-setter' or `gv-define-expander')
`get-setf-method' no longer exists (see "Incompatible Lisp Changes")
-+++
-** New compilation option `compilation-always-kill'.
-
-** Customize
----
-*** `custom-reset-button-menu' now defaults to t.

----
*** Changes are now highlighted using the same color scheme as in
modern VCSes. Deletions are displayed in red (new faces
`diff-refine-removed' and `smerge-refined-removed', and new definition
of `diff-removed'), insertions in green (new faces `diff-refine-added'
and `smerge-refined-added', and new definition of `diff-added').
----
*** The variable `diff-use-changed-face' defines whether to use the
face `diff-changed', or `diff-removed' and `diff-added' to highlight
changes in context diffs.
-+++
*** The new command `diff-delete-trailing-whitespace' removes trailing
whitespace introduced by a diff.
-** Dired
-+++
-*** `dired-do-async-shell-command' executes each file sequentially
-if the command ends in `;' (when operating on multiple files).
-Otherwise, it executes the command on each file in parallel.
----
-*** Typing M-n in the minibuffer of `dired-do-chmod', `dired-do-chgrp',
-`dired-do-chown', `dired-do-touch' pulls the file attributes of the
-file at point.

-mark/unmark/flag all files in the active region.
-+++
-*** The minibuffer default for `=' (`dired-diff) has changed.
-It is now the backup file for the file at point, if one exists.
-In Transient Mark mode the default is the file at the active mark.
-+++
-*** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers.
-The global binding for `M-=', `count-words-region' is in effect.

-*** ERC will look up server/channel names via auth-source and use any
-channel keys found.
-
-+++
-*** New option `erc-lurker-hide-list', similar to `erc-hide-list', but
-only applies to messages sent by lurkers.
-
-+++
-** Flymake uses fringe bitmaps to indicate errors and warnings.
-See `flymake-fringe-indicator-position', `flymake-error-bitmap' and
-`flymake-warning-bitmap'.
-
----
