* 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.
/usr/pkg/lib to the linker search path. You must add them yourself if
you want them.
----
-** On Mac OS X, configure no longer automatically adds the Fink /sw
-directories to the search path. You must add them yourself if you want them.
-
---
** 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).
-** 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.

* 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
++++
** 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'.
++++
+*** You can now click mouse-3 in the coding system indicator to invoke
+`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).
+** Minibuffer changes
+---
+*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
+next and previous path separator, respectively.
++++
+*** minibuffer-electric-default-mode can rewrite (default ...) to [...].
+Just set minibuffer-eldef-shorten-default to t before enabling the mode.
+
** 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.
-
+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.
-
++++
*** 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
-
++++
*** 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.
++++
** In the Package Menu, newly-available packages are listed as "new",
and sorted above the other "available" packages by default.
++++
** `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.
of the fatal signal, and a short backtrace on platforms like glibc
that support backtraces.
+---
** If your Emacs was built from a bzr checkout, the new variable
`emacs-bzr-version' contains information about the bzr revision used.
---
*** New input method `vietnamese-vni'.
+** Nextstep (GNUstep / Mac OS X) port changes
+---
+*** 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
+** Navigation command changes
+++
-** `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'.
-
----
-** 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.
-
-** 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.
+*** 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).
-
++++
*** 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'.
+
+---
+** 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.
+
++++
+** 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 text to put between collected texts for use with M-x
append-to-register and M-x prepend-to-register.
++++
** `C-u M-=' now counts lines/words/characters in the entire buffer.
-** New binding `M-g c' for `goto-char'.
-
-** M-x move-to-column, if called interactively with no prefix arg, now
-prompts for a column number.
-
++++
** New command `C-x r M-w' (copy-rectangle-as-kill).
It copies the region-rectangle as the last rectangle kill.
++++
** 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'.
* Changes in Specialized Modes and Packages in Emacs 24.3
** 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
+---
+*** The old options whose values specified faces to use were removed
(i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.).
** 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.
+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
that had to use `foo*' to avoid conflicts with pre-existing Elisp entities,
which have not been renamed to `cl-foo*' but just `cl-foo'.
-The old `cl' is now deprecated and is just a bunch of aliases that
-provide the old non-prefixed names.
+The old `cl' is now deprecated and is mainly just a bunch of aliases that
+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'.
++++
*** `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.
-** Compilation mode
++++
+*** The following methods of extending `setf' are obsolete
+(use features from gv.el instead):
+`define-modify-macro' (use `gv-letplace')
+`defsetf' (use `gv-define-simple-setter' or `gv-define-setter')
+`define-setf-expander' (use `gv-define-setter' or `gv-define-expander')
+** 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.
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.
+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.
specifying URL types which should be converted to remote file names at
the FFAP prompt. The default is now '("ftp").
+** Generic-x
+`javascript-generic-mode' is now an obsolete alias for `js-mode'.
+
** Ibuffer
*** New `derived-mode' filter, bound to `/ M'.
The old binding for `/ M' (filter by used-mode) is now bound to `/ m'.
** Mouse Avoidance mode
-
-The new variable `mouse-avoidance-banish-position' can now be used to
-customize Mouse Avoidance mode further.
++++
+*** New variable `mouse-avoidance-banish-position' specifies where the
+`banish' mouse avoidance setting moves the mouse.
+++
** notifications.el supports now version 1.2 of the Notifications API.
** 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.
+
** Python mode
A new version of python.el, which provides several new features, including:
that the sql statement will be terminated by a semicolon.
** Tabulated List and packages derived from it
-
++++
*** New command `tabulated-list-sort', bound to `S', sorts the column
at point, or the Nth column if a numeric prefix argument is given.
** Term
-
++++
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
The `url-retrieve' function now uses this to encode its URL argument,
in case that is not properly encoded.
+---
** VHDL mode
*** The free software compiler GHDL is supported (and now the default).
*** Accepts \r and \f as whitespace.
-** which-function-mode now applies to all applicable major modes by default.
+** Which Function mode
++++
+*** `which-func-modes' now defaults to t, so Which Function mode, when
+enabled, applies to all applicable major modes.
+---
+** winner-mode-hook now runs when the mode is disabled, as well as when it is
+enabled.
** FIXME something happened to ses.el, 2012-04-17.

+** The CL package's `get-setf-method' function no longer exists.
+Generalized variables are now part of core Emacs Lisp, and implemented
+differently to the way cl.el used to do it. It is not possible to
+define a compatible replacement for `get-setf-method'. See the file
+gv.el for internal details of the new implementation.

** Spelling changes.
Some Lisp symbols have been renamed to avoid problems with spelling
that is incorrect or inconsistent with how Emacs normally spells a word.

*** Set `debug-on-message' to enter the debugger when a certain
message is displayed in the echo area. This can be useful when trying
