* 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.
+You can explicitly require a specific version by passing
+--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
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.
+---
+** 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,
as it was confusingly-named and rarely useful.
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.
+
---
** Emacs uses libtinfo in preference to libncurses, if available.
(from the bin and libexec directories, respectively). The former is
no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
-** The configuration 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 native Windows user interface is available for Cygwin. Passing
+--with-w32 will configure a Cygwin emacs to use the Windows user
+interface instead of the default, X11.
\f
* Startup Changes in Emacs 24.3
++++
** Emacs no longer searches for `leim-list.el' files beneath the standard
lisp/ directory. There should not be any there anyway. If you have
been adding them there, put them somewhere else, eg site-lisp.
\f
* Changes in Emacs 24.3
+** minibuffer-electric-default-mode can rewrite (default ...) to [...].
+Just set minibuffer-eldef-shorten-default to t before enabling the mode.
+
++++
+** Most y-or-n prompts now allow you to scroll the selected window.
+Typing C-v or M-v at a y-or-n prompt scrolls forward or backward
+respectively, without exiting from the prompt.
+
+---
+** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
+next and previous path separator, respectively.
+
+** Mode line changes
+---
+*** New option `mode-line-default-help-echo' specifies the help text
+(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
+invokes `set-buffer-file-coding-system'.
+
** Help changes
++++
*** `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).
-** The function `current-time' now returns extended-format time stamps
-(HIGH LOW USEC PSEC) that use picosecond resolution; the PSEC
-component is new. PSEC is typically a multiple of 1000 on current
-machines. Other functions that use this format, such as
-file-attributes and format-time-string, have been changed accordingly.
-Old-format time stamps are still accepted.
-
-** New functions `system-users', `system-groups' return lists of the user
-name, group names known to the system (where possible).
-
-** If your Emacs was built from a bzr checkout, the new variable
-`emacs-bzr-version' contains information about which bzr revision was used.
-
** ImageMagick support, if available, 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 a relevant 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.
-
++++
*** 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.
-** Internationalization changes
+** Server and client changes
++++
+*** emacsclient now obeys string values for `initial-buffer-choice',
+if it is told to open a new frame without specifying any file to visit
+or expression to evaluate.
+---
+*** New option `server-auth-key' specifies a shared server key.
-*** New language environment: Persian.
+** In the Package Menu, newly-available packages are listed as "new",
+and sorted above the other "available" packages by default.
-** Face underlining can now use a wave.
-See the "Face Attributes" section of the Elisp manual.
++++
+** `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.
-** New fringe bitmap exclamation-mark.
+** Emacs now generates backtraces on fatal errors.
+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.
-** String values for `initial-buffer-choice' also apply to emacsclient
-frames, if emacsclient is only told to open a new frame without
-specifying any file to visit or expression to evaluate.
+---
+** If your Emacs was built from a bzr checkout, the new variable
+`emacs-bzr-version' contains information about the bzr revision used.
+++
-** You can prevent the creation of lock files by setting `create-lockfiles'
-to nil. Use with caution, and only if you really need to.
+** New variable `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.
-** Mode line changes
-
-*** New option `mode-line-default-help-echo' specifies the help text
-(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
-invokes `set-buffer-file-coding-system'.
-
+++
** Setting `enable-remote-dir-locals' to non-nil allows directory
local variables on remote hosts.
-+++
-** `insert-char' is now a command, and `ucs-insert' an obsolete alias
-for it.
-
+---
** The entry for PCL-CVS has been removed from the Tools menu.
The PCL-CVS commands are still available via the keyboard.
+** Internationalization changes
+---
+*** New language environment: Persian.
+---
+*** New input method `vietnamese-vni'.
+
+** NextStep/OSX port changes.
+---
+*** OSX 10.4 or newer is required to build Emacs.
+---
+*** Fullscreen and frame parameter fullscreen is supported.
+---
+*** A file dialog is used for open/save operations initiated from the
+menu/toolbar.
+
\f
* Editing Changes in Emacs 24.3
-** New option `yank-handled-properties' allows processing of text
-properties on yanked text, in more ways that are more general than
-just removing them, as done by `yank-excluded-properties'.
-
-** New option `delete-trailing-lines' specifies whether the M-x
-delete-trailing-whitespace command should delete trailing lines at the
-end of the buffer. It defaults to t.
+** Navigation command changes
++++
+*** 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 changes
+** 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).
++++
+*** 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.
-*** `search-whitespace-regexp' now acts on ordinary incremental search
-as well, so that each sequence of spaces in the search string matches
-any combination of one or more whitespace characters. To change this
-behavior, you can give `search-whitespace-regexp' a cons cell value,
-where the car and cdr specify values for ordinary and regular
-expression incremental search respectively.
-
-** M-x move-to-column, if called interactively with no prefix arg, now
-prompts for a column number.
++++
+** `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'.
-** `mouse-avoidance-banish-position' can now be used to customize
-`mouse-avoidance-mode' further.
+---
+** The `z' key no longer has a binding in most special modes.
+It used to be bound to `kill-this-buffer', but `z' is too easy to
+accidentally type.
-** `C-u M-=' now counts lines/words/characters in the entire buffer.
++++
+** 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.
-** `C-M-f' and `C-M-b' will now move to the path name separator
-character when doing minibuffer filename prompts.
+** Register changes
++++
+*** `C-x r +' is now overloaded to invoke `append-to-register.
++++
+*** New option `register-separator' specifies the register containing
+the text to put between collected texts for use with M-x
+append-to-register and M-x prepend-to-register.
-** `goto-char' is now bound to `M-g c'.
++++
+** `C-u M-=' now counts lines/words/characters in the entire buffer.
++++
** New command `C-x r M-w' (copy-rectangle-as-kill).
It copies the region-rectangle as the last rectangle kill.
-** New input method `vietnamese-vni'.
+** New option `yank-handled-properties' allows processing of text
+properties on yanked text, in more ways that are more general than
+just removing them, as done by `yank-excluded-properties'.
\f
* Changes in Specialized Modes and Packages in Emacs 24.3
-** Term changes
+** Apropos
+---
+*** 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.).
-The variables `term-default-fg-color' and `term-default-bg-color' are
-now deprecated in favor of the `term-face' face, that you can
-customize. Also, it is now possible to customize how are displayed the
-ANSI terminal colors and styles by customizing the corresponding
-`term-color-<COLOR>', `term-color-underline' and `term-color-bold'
-faces.
+** Buffer Menu
+This package has been rewritten to use Tabulated List mode.
+---
+*** Option `Buffer-menu-buffer+size-width' is now obsolete.
+Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead.
+
+** Calendar
+
++++
+*** You can customize the header text that appears above each calendar month.
+See the variable `calendar-month-header'.
+
++++
+*** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'.
+
++++
+*** The calendars produced by cal-html include holidays.
+Customize `cal-html-holidays' to change this.
** 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
A side effect is that vars without corresponding value are bound to nil
rather than making them unbound.
+** Compilation mode
+
+*** New option `compilation-always-kill'.
+
+** Customize
+
+*** `custom-reset-button-menu' now defaults to t.
+
+*** Non-option variables are never matched in `customize-apropos' and
+`customize-apropos-options' (i.e. the prefix argument does nothing for
+these commands now).
+
** Desktop
*** `desktop-path' no longer includes the "." directory. Desktop
files are now located in ~/.emacs.d by default.

+interrupted by C-g. `dbus-call-method-non-blocking' is obsolete.
+
++++
+*** Signals can be sent also as unicast message.
+
++++
+*** The argument list of `dbus-register-signal' has been extended,
+according to the new match rule types of D-Bus. See the manual for

++++
+*** `dbus-init-bus' supports private connections.
+
++++
+*** There is a new function `dbus-setenv'.
+
+** Diff mode
+
+*** 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-remove-trailing-whitespace' fixes trailing
+whitespace problems introduced by the 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.
+
+*** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'),
+`DEL' (`dired-unmark-backward'), `d' (`dired-flag-file-deletion')
+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.
+
+** Ediff now uses the same color scheme as Diff mode.
+
+** erc will look up server/channel names via auth-source and use the
+channel keys found, if any.
+
+** Flymake uses fringe bitmaps to indicate errors and warnings.
+See `flymake-fringe-indicator-position', `flymake-error-bitmap' and
+`flymake-warning-bitmap'.
+
+** Follow mode
+
+*** The obsolete variable `follow-mode-off-hook' has been removed.
+
+*** Follow mode no longer works by using advice.
+The option `follow-intercept-processes' has been removed.
+

+** Mouse Avoidance mode
+
+The new variable `mouse-avoidance-banish-position' can now be used to
+customize Mouse Avoidance mode further.
+
++++
+** notifications.el supports now version 1.2 of the Notifications API.
+The function `notifications-get-capabilities' returns the supported
+server properties.
+
+** In Perl mode, new option `perl-indent-parens-as-block' causes non-block
+closing brackets to be aligned with the line of the opening bracket.
+
+** In Proced mode, new command `proced-renice' renices marked processes.
+

* Lisp changes in Emacs 24.3
-** New functions `autoloadp' and `autoload-do-load'.
-
-** New function `posnp' to test if an object is a `posn'.
-
-** `function-get' fetches the property of a function, following aliases.
-
-** `toggle-read-only' accepts a second argument specifying whether to
-print a message, if called from Lisp.
+** New sampling-based Elisp profiler.
+Try M-x profiler-start ... M-x profiler-stop; and then M-x profiler-report.
+The sampling rate can be based on CPU time (only supported on some
+systems), or based on memory allocations.
** CL-style generalized variables are now in core Elisp.
-`setf' is autoloaded and `push' and `pop' accept generalized variables.
+`setf' is autoloaded; `push' and `pop' accept generalized variables.
** `defun' also accepts a (declare DECLS) form, like `defmacro'.
The interpretation of the DECLS is determined by `defun-declarations-alist'.
-** `macro-declaration-function' is obsolete, use `macro-declarations-alist'.
+** Completion
-** New function `set-temporary-overlay-map'.
+*** New function `completion-table-with-quoting' to handle completion
+in the presence of quoting, such as file completion in shell buffers.
-** New macros `setq-local' and `defvar-local'.
+*** New function `completion-table-subvert' to use an existing completion
+table, but with a different prefix.
+
+** Debugger changes
+
+*** New error type and new function `user-error'.
+These do not trigger the debugger.
+
+*** New option `debugger-bury-or-kill'.
+
+*** Set `debug-on-message' to enter the debugger when a certain
+message is displayed in the echo area. This can be useful when trying
+to work out which code is doing something.
+
+*** New var `inhibit-debugger', automatically set to prevent accidental
+recursive invocations.
-** New error type and new function `user-error'. Doesn't trigger the debugger.
+** Minibuffer
+
+*** `read-regexp' has a new argument HISTORY; the first argument PROMPT
+of `read-regexp' accepts a string ending with a colon and space, and its
+second argument DEFAULTS can be a list of strings accessible via M-n
+in the minibuffer ahead of other hard-coded useful regexp-related values.
+More commands use `read-regexp' now to read their regexp arguments.
** Window changes
*** The functions get-lru-window, get-mru-window and get-largest-window
now accept a third argument to avoid choosing the selected window.
-*** New display action alist `inhibit-switch-frame', if non-nil, tells
-display action functions to avoid changing which frame is selected.
+*** Additional values recognized for option `window-combination-limit'.
+
+*** New macro `with-temp-buffer-window'.
+
+*** `temp-buffer-resize-mode' no longer resizes windows that have been
+reused.
+
+*** New function `fit-frame-to-buffer' and new options
+`fit-frame-to-buffer' and `fit-frame-to-buffer-bottom-margin'.
+
+*** New display action functions `display-buffer-below-selected',
+`display-buffer-at-bottom' and `display-buffer-in-previous-window'.
+
+*** New display action alist entry `inhibit-switch-frame', if non-nil,
+tells display action functions to avoid changing which frame is
+selected.
+
+*** New display action alist entry `pop-up-frame-parameters', if
+non-nil, specifies frame parameters to give any newly-created frame.
-*** New display action alist `pop-up-frame-parameters', if non-nil,
-specifies frame parameters to give any newly-created frame.
+*** New display action alist entry `previous-window', if non-nil,
+specifies window to reuse in `display-buffer-in-previous-window'.
+
+*** New display action alist entries `window-height' and `window-width'
+to specify size of new window created by `display-buffer'.
*** The following variables are obsolete, as they can be replaced by
appropriate entries in the `display-buffer-alist' function introduced
in Emacs 24.1:
-
++++
**** `display-buffer-reuse-frames'
**** `special-display-regexps'
**** `special-display-frame-alist'
**** `special-display-buffer-names'
**** `special-display-function'
-
-** Completion
-
-*** New function `completion-table-with-quoting' to handle completion
-in the presence of quoting, such as file completion in shell buffers.
-
-*** New function `completion-table-subvert' to use an existing completion
-table, but with a different prefix.
+**** `display-buffer-function'
+**** `dired-shrink-to-fit'
** Time
-
+---
*** `current-time-string' no longer requires that its argument's year
must be in the range 1000..9999. It now works with any year supported
by the underlying C implementation.
+---
+*** `current-time' now returns extended-format time stamps
+(HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds.
+PSEC is typically a multiple of 1000 on current machines. Other
+functions that use this format, such as file-attributes and
+format-time-string, have been changed accordingly. Old-format time
+stamps are still accepted.
+---
+*** The format of timers in timer-list and timer-idle-list is now
+[TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS].
+The PSECS slot is new, and uses picosecond resolution. It can be
+accessed via the new timer--psecs accessor.
+
++++
+** Floating point functions now always return special values like NaN,
+instead of signaling errors, if given invalid args, e.g. (log -1.0).
+Previously, they returned NaNs on some platforms but signaled errors
+on others. The affected functions are acos, asin, tan, exp, expt,
+log, log10, sqrt, and mod.
+
+** Interpreted files are eagerly macro-expanded during load.
+This can significantly speed up execution of non-byte-compiled code,
+but can also bump into harmless and previously unnoticed cyclic
+dependencies. These should not be fatal: they will simply cause the
+macro-calls to be left for later expansion (as before), but will also
+result in a warning ("Eager macro-expansion skipped due to cycle")
+describing the cycle.
+
+** Miscellaneous new functions:
+
+*** `autoloadp'
+*** `autoload-do-load'
++++
+*** `buffer-narrowed-p' tests if the buffer is narrowed.
+*** `file-name-base' returns a file name sans directory and extension.
+*** `function-get' fetches a function property, following aliases.
++++
+*** `posnp' tests if an object is a `posn'.
+*** `set-temporary-overlay-map' sets up a temporary overlay map.
++++
+*** `system-users' returns the user names on the system.
++++
+*** `system-groups' returns the group names on the system.
+*** `tty-top-frame' returns the topmost frame of a text terminal.
-** New function file-name-base.
+** New macros `setq-local' and `defvar-local'.
-** New function `tty-top-frame' returns the topmost frame of a text terminal.
+** New fringe bitmap `exclamation-mark'.
+
+** Face underlining can now use a wave.
+See the "Face Attributes" section of the Elisp manual.
+
+** The following functions and variables are obsolete:
+
+*** `automount-dir-prefix'
+*** `buffer-has-markers-at'
+*** `macro-declaration-function' (use `macro-declarations-alist')
+*** `window-system-version'
+*** `dired-pop-to-buffer' (use `dired-mark-pop-up')
+*** `query-replace-interactive'
-** `automount-dir-prefix' is obsolete.
-** `buffer-has-markers-at' is obsolete.

* Changes in Emacs 24.3 on non-free operating systems
-** New configure.bat options on MS-Windows:
-
-*** --without-libxml2 omits support for libxml2, even if its presence
-is detected.
++++
+** On MS Windows, you can pass --without-libxml2 to configure.bat to omit
+support for libxml2, even if its presence is detected.
** When invoked with the -nw switch to run on the Windows text-mode terminal,
Emacs now supports mouse highlight, help-echo (in the echo area), and
-mouse-autoselect-window.
+`mouse-autoselect-window'.
+
+** Two new functions are available in Cygwin builds:
+`cygwin-convert-path-from-windows' and `cygwin-convert-path-to-windows'.
+These functions allow Lisp code to access the Cygwin file-name mapping
+machinery to convert between Cygwin and Windows-native file names.
-** On MS-Windows Vista and later Emacs now supports symbolic links.

+*** SMTPmail defaults to using the address in the From: header as the
+SMTP MAIL FROM envelope. To override this, set `mail-envelope-from'
+to the address you wish to use instead.

** SQL mode
*** New options `sql-port', `sql-connection-alist', `sql-send-terminator',
