with a prefix argument or by typing C-u C-h C-n.

Temporary note:
+++ indicates that the appropriate manual has already been updated.
--- means no change in the manuals is called for.
When you add a new item, please add it without either +++ or ---
so we will look at it and add it to the manual.

\f
* Installation Changes in Emacs 24.3

** 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 '--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.

---
** 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.

---
** 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.

\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.

---
** The `--no-site-lisp' command line option now works for Nextstep builds.

\f
* Changes in Emacs 24.3

** 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.

** 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.

** 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

*** New language environment: Persian.

** Face underlining can now use a wave.
See the "Face Attributes" section of the Elisp manual.

** New fringe bitmap exclamation-mark.

** 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.

+++
** You can prevent the creation of lock files by setting `create-lockfiles'
to nil.  Use with caution, and only if you really need to.

+++
** 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.

\f
* Editing Changes in Emacs 24.3

** 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 `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.

** Search changes

*** 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.

*** `M-s SPC' in Isearch toggles whitespace matching mode
in both ordinary and regexp incremental search, so that each
sequence of spaces in the search string matches any combination
of one or more whitespace characters defined by the variable
`search-whitespace-regexp'.  In ordinary incremental search,
`isearch-toggle-lax-whitespace' toggles the value of the variable
`isearch-lax-whitespace'.  In regexp incremental search, it toggles
the value of the variable `isearch-regexp-lax-whitespace'.

** query-replace changes

*** When new option `replace-lax-whitespace' is non-nil,
and you enter a space or spaces in the strings or regexps
to be replaced, `query-replace' will match any sequence matched
by the regexp `search-whitespace-regexp'.

** M-x move-to-column, if called interactively with no prefix arg, now
prompts for a column number.

** `mouse-avoidance-banish-position' can now be used to customize
`mouse-avoidance-mode' further.

** `C-u M-=' now counts lines/words/characters in the entire buffer.

** `C-M-f' and `C-M-b' will now move to the path name separator
character when doing minibuffer filename prompts.

** `goto-char' is now bound to `M-g c'.

** 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'.

\f
* Changes in Specialized Modes and Packages in Emacs 24.3

** Compilation has a new `compilation-always-kill' configuration variable.

** Term changes

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.

** 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).

If `cl' provided a feature under the name `foo', then `cl-lib' provides it
under the name `cl-foo' instead, with the exceptions of the few definitions
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.

*** `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.

*** `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.

** Desktop

*** `desktop-path' no longer includes the "." directory.  Desktop
files are now located in ~/.emacs.d by default.

** Python mode

A new version of python.el, which provides several new features, including:
per-buffer shells, better indentation, Python 3 support, and improved
shell-interaction compatible with iPython (and virtually any other
text based shell).

*** Some user options have been replaced/renamed:
Old defcustom:                | New defcustom:
python-indent                 | python-indent-offset
python-guess-indent           | python-indent-guess-indent-offset
python-pdbtrack-do-tracking-p | python-pdbtrack-activate
python-use-skeletons          | python-skeleton-autoinsert

*** Some user options have been removed:

**** `python-indent-string-contents': Strings are never indented.

**** `python-honour-comment-indentation':
Comments are never considered as indentation markers themselves.

**** `python-continuation-offset': Indentation is automatically
calculated in a pep8 compliant way depending on the context.

**** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist':
Have no direct mapping as the shell interaction is completely different.

**** `python-python-command', `python-jython-command':
Replaced by `python-shell-interpreter'.

**** `inferior-python-filter-regexp', `python-remove-cwd-from-path',
`python-pdbtrack-minor-mode-string', `python-source-modes':
No longer relevant.

*** Some commands have been replaced:
Old command               | New command
python-insert-class       | python-skeleton-class
python-insert-def         | python-skeleton-def
python-insert-for         | python-skeleton-for
python-insert-if          | python-skeleton-if
python-insert-try/except  | python-skeleton-try
python-insert-try/finally | python-skeleton-try
python-insert-while       | python-skeleton-while
python-find-function      | python-nav-jump-to-defun
python-next-statement     | python-nav-forward-sentence
python-previous-statement | python-nav-backward-sentence
python-send-buffer        | python-shell-send-buffer
python-send-defun         | python-shell-send-defun
python-send-region        | python-shell-send-region
python-send-region-and-go | Emulate with python-shell-send-region and
                            python-shell-switch-to-shell
python-send-string        | python-shell-send-string
python-switch-to-python   | python-shell-switch-to-shell
python-describe-symbol    | python-eldoc-at-point

** VHDL mode

*** The free software compiler GHDL is supported (and now the default).

*** Support for the VHDL-AMS packages has been added/updated.

*** Updated to the 2002 revision of the VHDL standard.

*** Accepts \r and \f as whitespace.

** Diff mode

Faces for changes now use the same diff color scheme as in modern VCSes
where 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.

** Ediff now uses the same color scheme as Diff mode
on high color displays.

** Flymake uses fringe bitmaps to indicate errors and warnings.
See flymake-fringe-indicator-position, flymake-error-bitmap and
flymake-warning-bitmap.

** `sh-script'
*** Pairing of parens/quotes uses electric-pair-mode instead of skeleton-pair.
*** `sh-electric-here-document-mode' now controls auto-insertion of here-docs.
*** `sh-use-smie' lets you choose a new indentation and navigation code.

** reStructuredText mode

*** Rebind nearly all keys making room for more keys and complying
better to usage in other modes.  Describe bindings with C-c C-h.

*** Major revision of indentation working very similar to other
modes.  TAB is your friend.

*** Major revision of filling working fine with most of
reStructuredText syntax.  Support auto-filling.

*** Major revision of comment handling.

*** Major revision of fontification working with `jit-lock-mode'.

*** Cover reStructuredText syntax more closely.  Improve
the experience for Sphinx users.

*** `rst-insert-list' inserts new list or continues existing lists.

*** Extend correct and improve customization.

*** Negative prefix argument always works for `rst-adjust'.

*** Reset window configuration after displaying TOC.

*** Package version in `rst-version'.

** New `derived-mode' filter for Ibuffer, bound to `/ M'.
`/ m' is now bound to filter by used-mode, which used to be bound to `/ M'.

** 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.).

** 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

*** The calendars produced by cal-html include holidays.
Customize cal-html-holidays to change this.

** 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).

** erc will look up server/channel names via auth-source and use the
channel keys found, if any.

** 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.

** Shell

*** New option `async-shell-command-buffer' specifies what buffer to use
for a new asynchronous shell command when the default output buffer
`*Async Shell Command*' is already taken by another running command.

** FFAP

*** The option `ffap-url-unwrap-remote' can now be a list of strings,
specifying URL types which should be converted to remote file names at
the FFAP prompt.  The default is now '("ftp").

** 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.

** The `server-auth-key' variable can be used to set a permanent
shared key for Emacs Server.

** 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.

** FIXME something happened to ses.el, 2012-04-17.

** which-function-mode now applies to all applicable major modes by default.

** Tramp

+++
*** The syntax has been extended in order to allow ad-hoc proxy
definitions.  See the manual for details.

+++
*** Remote processes are now supported also on remote Windows host.

** D-Bus

+++
*** New variables `dbus-compiled-version' and `dbus-runtime-version'.

+++
*** The D-Bus object manager interface is implemented.

+++
*** Variables of type :(u)int32 and :(u)int64 accept floating points,
if their value does not fit into Emacs's integer range.

+++
*** The function `dbus-call-method' works non-blocking now, it can be
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
details.

+++
*** `dbus-init-bus' supports private connections.

+++
*** There is a new function `dbus-setenv'.

+++
** notifications.el supports now version 1.2 of the Notifications API.
The function `notifications-get-capabilities' returns the supported
server properties.

** Package Menu

*** Newly-available packages are listed in the Package Menu as "new",
and sorted above the other "available" packages by default.

** 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.

** URL

*** Structs made by `url-generic-parse-url' have nil `attributes' slot.
Previously, this slot stored semicolon-separated attribute-value pairs
appended to some imap URLs, but this is not compatible with RFC 3986.
So now the `filename' slot stores the entire path and query components
and the `attributes' slot is always nil.

*** New function `url-encode-url' for encoding a URI string.
The `url-retrieve' function now uses this to encode its URL argument,
in case that is not properly encoded.

** Obsolete packages:

*** assoc.el
In most cases, assoc+member+push+delq work just as well.
And in any case it's just a terrible package: ugly semantics, terrible
inefficiency, and not namespace-clean.

*** bruce.el

*** ledit.el

*** mailpost.el

*** mouse-sel.el

*** patcomp.el

*** cust-print.el

\f
* New Modes and Packages in Emacs 24.3
\f
* Incompatible Lisp Changes in Emacs 24.3

** (random) by default now returns a different random sequence in
every Emacs run.  Use (random S), where S is a string, to set the
random seed to a value based on S, in order to get a repeatable
sequence in later calls.

** The function `x-select-font' can return a font spec, instead of a
font name as a string.  Whether it returns a font spec or a font name
depends on the graphical library.

** If the NEWTEXT arg to `replace-match' contains a substring "\?",
that substring is inserted literally even if the LITERAL arg is
non-nil, instead of causing an error to be signaled.

+++
** Docstrings starting with `*' no longer indicate user options.
Only variables defined using `defcustom' are considered user options.
The function `user-variable-p' is now an obsolete alias for
`custom-variable-p'.

+++
** The return values of `defalias', `defun' and `defmacro' have changed,
and are now undefined.  For backwards compatibility, defun and
defmacro currently return the name of the newly defined function/macro
but this should not be relied upon.

** `face-spec-set' no longer sets frame-specific attributes when the
third argument is a frame (that usage was obsolete since Emacs 22.2).

+++
** The arguments of `dbus-register-signal' are no longer just strings,
but keywords or keyword-string pairs.  The old argument list will
still be supported for Emacs 24.x.

** 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.

*** Renamed functions

**** hangul-input-method-inactivate -> hangul-input-method-deactivate
**** inactivate-input-method -> deactivate-input-method
**** quail-inactivate -> quail-deactivate
**** robin-inactivate -> robin-deactivate
**** viper-inactivate-input-method -> viper-deactivate-input-method
**** viper-inactivate-input-method-action ->
     viper-deactivate-input-method-action
**** ucs-input-inactivate -> ucs-input-deactivate

*** Renamed hooks
The old hooks are still supported for backward compatibility, but they
are deprecated and will be removed eventually.

**** input-method-inactivate-hook -> input-method-deactivate-hook
**** robin-inactivate-hook -> robin-deactivate-hook
**** quail-inactivate-hook -> quail-deactivate-hook

*** Renamed Lisp variables

**** follow-deactive-menu -> follow-inactive-menu
**** inactivate-current-input-method-function ->
     deactivate-current-input-method-function

** The following obsolete variables and varaliases have been removed:

*** `facemenu-unlisted-faces'
*** `rmail-decode-mime-charset'
*** `last-input-char' and `last-command-char'

\f
* Lisp changes in Emacs 24.3

** Interpreted files get 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 describing
the cycle.

** New minor mode `read-only-mode' to replace toggle-read-only (now obsolete).

** 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.

** CL-style generalized variables are now in core Elisp.
`setf' is autoloaded and `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'.

** New function `set-temporary-overlay-map'.

** New macros `setq-local' and `defvar-local'.

** New error type and new function `user-error'.  Doesn't trigger the debugger.

+++
** New utility function `buffer-narrowed-p'.

** 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 macro with-temp-buffer-window.

*** New option temp-buffer-resize-frames.

*** New function fit-frame-to-buffer and new option
    fit-frame-to-buffer-bottom-margin.

*** New display action function display-buffer-below-selected.

*** New display action alist `inhibit-switch-frame', if non-nil, tells
display action functions to avoid changing which frame is selected.

*** New display action alist `pop-up-frame-parameters', if non-nil,
specifies frame parameters to give any newly-created frame.

*** 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.

** 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.

** New function file-name-base.

** New function `tty-top-frame' returns the topmost frame of a text terminal.

** `automount-dir-prefix' is obsolete.
** `buffer-has-markers-at' is obsolete.
** `window-system-version' is obsolete.
\f
* 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.

** 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.

** On MS-Windows Vista and later Emacs now supports symbolic links.
\f
* Changes in Emacs 24.2

** This is mainly a bug-fix release.

\f
* Installation Changes in Emacs 24.1

** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
to configure.  Note that other libraries used by Emacs, RSVG and GConf,
also depend on Gtk+.  You can disable them with --without-rsvg and
--without-gconf.

** Emacs can be compiled with GnuTLS support.
This happens by default if a suitably recent version of the library is
found at build time.  To prevent this, use the configure option
`--without-gnutls'.  See below for GnuTLS features.

** Emacs can be compiled with SELinux support.
This happens by default if a suitably recent version of the library is
found at build time.  To prevent this, use the configure option
`--without-selinux'.  See below for SELinux features.

** Emacs can be compiled with ImageMagick support.
This happens by default if a suitably recent version of the library is
found at build time.  To prevent this, use the configure option
`--without-imagemagick'.  See below for ImageMagick features.
This feature is not available for the Nextstep or MS ports.

** Emacs can be compiled with libxml2 support.
This happens by default if a suitably recent version of the library is
found at build time.  To prevent this, use the configure option
`--without-xml2'.  See below for libxml2 features.

** By default, the installed Info and man pages are compressed.
You can disable this by configuring --without-compress-info.

** New configure option --with-wide-int.
With it, Emacs integers typically have 62 bits, even on 32-bit machines.
On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB
to about 2 GiB.

** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost.
These provide no new functionality, they just remove the need to edit
lib-src/Makefile by hand in order to use the associated features.

** New configure option --enable-use-lisp-union-type.
This is only useful for Emacs developers to debug certain types of bugs.
This is not a new feature; only the configure flag is new.

** The standalone programs digest-doc and sorted-doc are removed.
Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'.

** The standalone program `fakemail' is removed.
If you need it, feedmail.el provides a superset of the functionality.

\f
* Startup Changes in Emacs 24.1

** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
command line arguments, and the EMACS_UNIBYTE environment variable, no
longer have any effect.  (They were declared obsolete in Emacs 23.)

** New command line option `--no-site-lisp' removes site-lisp directories
from load-path.  -Q now implies this.  This option does not affect the
EMACSLOADPATH environment variable (and hence has no effect for
Nextstep builds).

\f
* Changes in Emacs 24.1

** Completion

*** Many packages now use the `completion-at-point' command,
rather than implementing separate completion commands.

*** `completion-at-point' now handles tags and semantic completion.

*** Completion in a non-minibuffer now tries to detect the end of completion
and pops down the *Completions* buffer accordingly.

*** New option `completion-cycle-threshold' allows completion cycling.

*** New option `completion-category-overrides' for overriding the
default completion style in certain circumstances.

*** New completion style `substring'.

*** Completion of buffer names uses `substring' completion by default.

*** The option `widget-complete-field' has been removed.

** Mail changes

*** The first time you try sending mail, Emacs asks for a mail method.
This is implemented by a new default for `send-mail-function', which
is `sendmail-query-once'.  This offers to use the smtpmail package, or
to use the old defaults relying on external mail facilities
(`sendmail-send-it' on GNU/Linux and other Unix-like systems, and
`mailclient-send-it' on Windows).

*** Typing C-c m in the buffer made by M-x report-emacs-bug transfers
the report to your desktop's preferred mail client, if there is one.
This uses either the "xdg-email" utility, or Mac OS's "open" command.

*** See Changes in Specialized Modes and Packages for SMTPmail changes
and Mail mode changes

** Emacs server and client changes

*** New option `server-port' specifies the port for TCP Emacs servers.

*** New emacsclient argument -q/--quiet suppresses some status messages.

*** New emacsclient argument --frame-parameters specifies the frame
parameters of any newly-created graphical frame.

*** If emacsclient shuts down due to Emacs signaling an error,
its exit status is 1.

*** New emacsclient argument --parent-id ID.
This opens a client frame in parent X window ID, via XEmbed, similar
to the --parent-id argument to Emacs.

** Internationalization changes

*** Emacs now supports display and editing of bidirectional text.
Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are
displayed in the correct visual order as expected by users of those
scripts.  The display reordering is a "full bidirectionality" class
implementation of the Unicode Bidirectional Algorithm (UBA).  Buffers
with no RTL text should look exactly the same as before.

**** New buffer-local variable `bidi-display-reordering'.
To disable display reordering in a buffer, change this to nil.

**** New buffer-local variable `bidi-paragraph-direction'.
If nil (the default), Emacs determines the base direction of each
paragraph from its text, as specified by the UBA.  Setting the value
to `right-to-left' or `left-to-right' forces a base direction on each
paragraph.

Paragraphs with right-to-left base direction are displayed starting at
the right window edge.

*** Enhanced support for characters with no glyphs in available fonts,
or, on text terminals, characters that cannot be encoded by the
terminal coding system.  The new option `glyphless-char-display-control'
specifies how to display them: as a hexadecimal code in a box, a thin
1-pixel space, an empty box, etc.

*** New input methods for Farsi and Bulgarian
(farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic).

*** `nobreak-char-display' now also highlights Unicode hyphen chars
(U+2010 and U+2011).

*** New Hebrew translation of the Emacs Tutorial.
Type `C-u C-h t' to choose it in case your language setup doesn't
automatically select it.

** An Emacs Lisp package manager is now included.
This is a convenient way to download and install additional packages,
from a package repository at http://elpa.gnu.org.

*** M-x list-packages shows a list of packages, which can be
selected for installation.

*** New command `describe-package', bound to `C-h P'.

*** By default, all installed packages are loaded automatically when
Emacs starts up.  To disable this, set `package-enable-at-startup' to
nil.  To specify the packages to load, customize `package-load-list'.

** Custom theme changes

*** New command `M-x customize-themes', which provides a convenient
interface for enabling and disabling Custom themes.

*** New option `custom-theme-load-path' is the load path for themes.
Emacs no longer looks for Custom themes in `load-path'.  The default
value of `custom-theme-load-path' says to look for themes in
`custom-theme-directory', followed by a subdirectory of
`data-directory' named "themes/", which contains a small selection of
built-in Custom themes.

*** New option `custom-safe-themes' records known-safe theme files.
If a theme is not in this list, Emacs queries before loading it, and
offers to save the theme to `custom-safe-themes' automatically.  By
default, all themes included in Emacs are treated as safe.

** Improved GTK integration

*** GTK scroll-bars are now placed on the right by default.
The function `set-scroll-bar-mode' can change this.

*** GTK tool bars can have just text, just images or images and text.
Customize `tool-bar-style' to choose the style.  On a Gnome desktop,
the default is taken from desktop settings.

*** GTK tool bars can be placed on any edge of the frame.
The frame-parameter tool-bar-position controls this.  It takes the
values top, left, right or bottom.  The Options => Show/Hide menu has
entries for this.

*** The default colors for selected text (the `region' face) are taken
from the GTK theme when Emacs is built with GTK.

*** Emacs uses GTK tooltips by default if built with GTK.
You can disable this by changing `x-gtk-use-system-tooltips' to nil.

** Graphical interface changes

*** On graphical displays, the mode-line no longer ends in dashes.
Also, the first dash (which does not indicate anything) is just
displayed as a space.

*** `menu-bar-select-buffer-function' lets you choose another operation
instead of `switch-to-buffer' when selecting an item in the Buffers menu.

*** Lucid menus and dialogs can display antialiased fonts if Emacs is
built with Xft.  These fonts can be set via X resources, for example:
Emacs.pane.menubar.font: Courier-12

** Exiting changes

*** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP,
or if it receives a SIGINT signal in batch mode.

*** `kill-emacs-hook' is now also run in batch mode.
Third-party code which adds to `kill-emacs-hook' should check if they
do the right thing in batch mode.

** Scrolling changes

*** New scrolling commands `scroll-up-command' and `scroll-down-command'
(bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
of buffer at first key-press (instead they move to top/bottom of buffer)
when `scroll-error-top-bottom' is non-nil.

*** New option `scroll-error-top-bottom' (see above).

*** New scrolling commands `scroll-up-line' and `scroll-down-line'
scroll a line instead of full screen.

*** New property `scroll-command' should be set on a command's symbol to
define it as a scroll command affected by `scroll-preserve-screen-position'.

*** If you customize `scroll-conservatively' to a value greater than 100,
Emacs will never recenter point in the window when it scrolls due to
cursor motion commands or commands that move point (e.f., `M-g M-g').
Previously, you needed to use `most-positive-fixnum' as the value of
`scroll-conservatively' to achieve the same effect.

*** "Aggressive" scrolling now honors the scroll margins.
If you customize `scroll-up-aggressively' or
`scroll-down-aggressively' and move point off the window, Emacs now
scrolls the window so as to avoid positioning point inside the scroll
margin.

** Basic SELinux support has been added.
This requires Emacs to be linked with libselinux at build time.

*** Emacs preserves the SELinux file context when backing up.
Also, the function `copy-file' has an extra optional argument for
preserving SELinux context, and the return value of `backup-buffer'
now includes the SELinux context.

*** New functions `file-selinux-context' and `set-file-selinux-context'
get and set the SELinux context of a file.

** Trash changes

*** `delete-by-moving-to-trash' now only affects commands that specify
trashing.  This avoids inadvertently trashing temporary files.

*** Calling `delete-file' or `delete-directory' with a prefix argument
now forces true deletion, regardless of `delete-by-moving-to-trash'.

** File- and directory-local variable changes

*** You can stop directory local vars from applying to subdirectories.
Add an element (subdirs . nil) to the alist portion of any variables
settings to indicate that the section should not apply to
subdirectories.

*** Directory local variables can apply to some file-less buffers.
Affected modes include dired, vc-dir, and log-edit.  For example,
adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will
turn on `whitespace-mode' for *vc-diff* buffers.  Modes should call
`hack-dir-local-variables-non-file-buffer' to support this.

*** Using "mode: MINOR-MODE" to enable a minor mode is deprecated.
Instead, use "eval: (minor-mode 1)".

*** The variable `inhibit-first-line-modes-regexps' has been renamed
to `inhibit-local-variables-regexps'.  As the name suggests, it now
applies to ALL file local variables, not just -*- lines.  The
associated `inhibit-first-line-modes-suffixes' has been renamed in the
corresponding way.

** Window changes

*** The `quit-window' command now restores the last buffer displayed
in the quitted window.

*** Resizing an Emacs frame now preserves proportional window sizes,
modulo restrictions like window minimum sizes and fixed-size windows.

*** The behavior of `display-buffer' is now customizable in detail.

**** New option `display-buffer-base-action' specifies a list of
user-determined display "actions" (functions and optional arguments
for choosing the displaying window).

This takes precedence over the default display action, which is
specified by `display-buffer-fallback-action'.

**** New option `display-buffer-alist' maps buffer name regexps to
display actions, taking precedence over `display-buffer-base-action'.

*** New option `window-combination-limit'.
The new option `window-combination-limit' allows to return the space
obtained for resizing or creating a window more reliably to the window
from which such space was obtained.

*** New option `window-combination-resize'.
The new option `window-combination-resize' allows to split a window that
otherwise cannot be split because it's too small by stealing space from
other windows in the same combination.  Subsequent resizing or deletion
of the window will resize all windows in the same combination as well.

*** New option `frame-auto-hide-function' lets you choose between
iconifying or deleting a frame when burying a buffer in a dedicated
frame, or quitting a window showing a buffer in a frame of its own.

*** New commands `maximize-window' and `minimize-window'.
These maximize and minimize the size of a window within its frame.

*** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'.
These functions allow to navigate through the live buffers that have
been shown in a specific window.

** Minibuffer changes

*** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
This is handy for minibuffer-only frames, and is also used for the feature
where mouse-1 pops up *Messages*"', which can now easily be changed.

*** Minibuffers set `truncate-lines' to nil.
If you want to change the value to something else, you could use
for example `minibuffer-setup-hook'.

** `auto-mode-case-fold' is now enabled by default.

** `backup-by-copying-when-mismatch' now defaults to t.

** New basic faces `error', `warning', `success'.
These are used to highlight text indicating failure, caution or
successful operation.

** New option `list-colors-sort' defines the color sort order
for `list-colors-display'.

** The variable `focus-follows-mouse' now always defaults to nil.

\f
* Editing Changes in Emacs 24.1

** Search changes

*** C-y in Isearch is now bound to `isearch-yank-kill', instead of
`isearch-yank-line'.

*** M-y in Isearch is now bound to `isearch-yank-pop', instead of
`isearch-yank-kill'.

*** M-s C-e in Isearch is now bound to `isearch-yank-line'.

** New commands `count-words-region' and `count-words'.

*** M-= is bound to `count-words-region', not `count-lines-region'.
The `count-words-region' command, when called interactively, reports
the number of lines, words, and characters in the region.  It is a
superset of the old `count-lines-region', which is now an obsolete
alias for it.

** The command `just-one-space' (M-SPC), if given a negative argument,
also deletes newlines around point.

** Deletion changes

*** New option `delete-active-region'.
If non-nil, [delete] and DEL delete the region if it is active and no
prefix argument is given.  If set to `kill', those commands kill
instead.

*** New command `delete-forward-char', bound to [delete].
This is meant for interactive use, and obeys `delete-active-region'.
The command `delete-char' does not obey `delete-active-region'.

*** `delete-backward-char' is now a Lisp function.
Apart from obeying `delete-active-region', its behavior is unchanged.
However, the byte compiler now warns if it is called from Lisp; Lisp
callers should use delete-char with a negative argument instead.

*** The option `mouse-region-delete-keys' has been deleted.

** Selection changes.

The default handling of clipboard and primary selections has been
changed to conform with modern X applications.  In short, most
commands for killing and yanking text now use the clipboard, while
mouse commands use the primary selection.

In the following, we provide a list of these changes, followed by a
list of steps to get the old behavior back if you prefer that.

*** `select-active-regions' now defaults to t.
Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
the kill ring.  The selected text is put in the primary selection, if
the system possesses a separate primary selection facility (e.g. X).

**** `select-active-regions' also accepts a new value, `only'.
This means to only set the primary selection for temporarily active
regions (usually made by mouse-dragging or shift-selection);
"ordinary" active regions, such as those made with C-SPC followed by
point motion, do not alter the primary selection.

**** `mouse-drag-copy-region' now defaults to nil.

*** mouse-2 is now bound to `mouse-yank-primary'.
This pastes from the primary selection, ignoring the kill-ring.
Previously, mouse-2 was bound to `mouse-yank-at-click'.

*** `x-select-enable-clipboard' now defaults to t on all platforms.

*** `x-select-enable-primary' now defaults to nil.
Thus, commands that kill text or copy it to the kill-ring (such as
M-w, C-w, and C-k) also use the clipboard---not the primary selection.

**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
exactly equivalent to M-w, C-w, and C-y respectively.

**** Note that on MS-Windows, `x-select-enable-clipboard' was already
non-nil by default, as Windows does not support the primary selection
between applications.

*** To return to the previous behavior, do the following:

**** Change `select-active-regions' to nil.
**** Change `mouse-drag-copy-region' to t.
**** Change `x-select-enable-primary' to t (on X only).
**** Change `x-select-enable-clipboard' to nil.
**** Bind `mouse-yank-at-click' to mouse-2.

*** Support for X cut buffers has been removed.

*** X clipboard managers are now supported.
To inhibit this, change `x-select-enable-clipboard-manager' to nil.

** New command `C-x r N' (`rectangle-number-lines') numbers the lines
in the current rectangle.  With a prefix argument, this prompts for a
number to count from and for a format string.

** `redisplay-dont-pause' now defaults to t.
This makes Emacs feel more responsive to editing commands that arrive
at high rate, e.g. if you lean on some key, because stopping redisplay
in the middle (when this variable is nil) forces more expensive
updates later on, and Emacs appears to be unable to keep up.

** The behavior of <TAB> for active regions in Text mode has changed.
In Text and related modes, typing <TAB> (`indent-for-tab-command')
when the region is active causes Emacs to indent all the lines in the
region, aligning them with the line previous to the first line in the
region (or with the left margin if there is no previous line).

** When `occur' is called with a prefix argument, matching strings are
collected into the `*Occur*' buffer without line numbers.  If there
are parenthesized subexpressions in the specified regexp, `occur'
reads replacement text that may contain \\& and \\N whose convention
follows `replace-match'.

\f
* Changes in Specialized Modes and Packages in Emacs 24.1

** Archive Mode has basic support for browsing and updating 7z archives.

** BibTeX mode

*** BibTeX mode now supports biblatex.
Use the variable `bibtex-dialect' to select different BibTeX dialects.
`bibtex-entry-field-alist' is now an obsolete alias for
`bibtex-BibTeX-entry-alist'.

*** New command `bibtex-search-entries', bound to C-c C-a.

*** New `bibtex-entry-format' option `sort-fields', disabled by default.

*** New variable `bibtex-search-entry-globally'.

** Browse-url

*** New option `browse-url-mailto-function' specifies how to handle "mailto:"s.

*** The default browser used by the package is now the "xdg-open" program,
on platforms that support it.  This calls your desktop's preferred browser.

** Calendar, Diary, and Appt

*** Diary entries can contain non-printing "comments".
See the variable `diary-comment-start'.

*** Appointments can specify their individual warning times.
See the variable `appt-warning-time-regexp'.

*** The function specified by `appt-disp-window-function' may be passed
lists of arguments if multiple appointments are due at similar times.
If you are using a custom function for this, you should update it.

*** New function `diary-hebrew-birthday'.

*** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array'
may no longer be nil, but must all be strings.

*** The obsolete (since Emacs 22.1) method of enabling the appt
package by adding `appt-make-list' to `diary-hook' has been removed.
Use `appt-activate' instead.

*** Some appt variables (obsolete since Emacs 22.1) have been removed:
appt-issue-message (use the function appt-activate)
appt-visible/appt-msg-window (use the variable appt-display-format)

*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
view-diary-entries, list-diary-entries, show-all-diary-entries

** CC Mode

*** New feature to "guess" the style in an existing buffer.
The main entry point is M-x c-guess.

*** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang).

*** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes.
Thus C-M-a will, by default, go to the beginning of the immediate function,
not the top level.

*** "Macros with semicolons" can be registered for correct indentation.
Where such a macro ends a line (no semicolon) the next statement is no longer
parsed as a statement continuation.

** Comint and modes derived from it use the standard completion code.

** Compilation mode

*** Compilation mode can be used without Font Lock mode.
`compilation-parse-errors-function' is now obsolete.

*** New variable `compilation-filter-start', which is bound while
`compilation-filter-hook' runs.  It records the start position of the
text inserted by `compilation-filter'.

*** `compilation-error-screen-columns' and `compilation-first-column'
are obeyed in the editing buffer.  So programming language modes can
set them, whereas previously only the value in the *Compilation*
buffer was used.

** Customize

*** Customize buffers now contain a search field.
The search is performed using `customize-apropos'.
To turn off the search field, set `custom-search-field' to nil.

*** Options in customize group buffers start out hidden if not customized.
Use the arrow to the left of the option name to toggle visibility.

*** custom-buffer-sort-alphabetically now defaults to t.

*** The color widget now has a "Choose" button, which allows you to
choose a color via `list-colors-display'.

** D-Bus

*** It is now possible to access buses other than the default system
or session bus.

*** The `dbus-register-method' and `dbus-register-property' functions
optionally do not register names.

*** The new function `dbus-register-service' registers a known service
name on a D-Bus without also registering a property or a method.

** Dired-x

*** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'),
if called with a prefix argument, read a file name from the minibuffer
instead of using the current buffer.

*** The "dired local variables" feature of Dired-x is obsolete.
The standard directory local variables feature replaces it.

** ERC changes

*** New options `erc-autojoin-timing' and `erc-autojoin-delay',
controlling attempts to autojoin a channel.

*** New variable `erc-coding-system-precedence': If we use `undecided'
as the server coding system, this variable will then be consulted.
The default is to decode strings that can be decoded as utf-8 as
utf-8, and do the normal `undecided' decoding for the rest.

** Eshell changes

*** The default value of `eshell-directory-name' has changed
to be an "eshell" directory in `user-emacs-directory'.
The old "~/.eshell/" directory is still used if it exists, though.

** gdb-mi

*** The M-x gdb command now uses the GDB Machine Interface protocol.
It now supports multithread non-stop debugging and simultaneous
debugging of several threads.

** Image mode

*** RET (`image-toggle-animation') toggles animation, if applicable.
Animation plays once, unless the option `image-animate-loop' is non-nil.

** Info

*** New command M-x info-display-manual displays a named Info manual.
If that manual is already visited in some Info buffer, it displays
that buffer.  (This is handy if you have many manuals in many *info*
buffers, and don't remember the name of the buffer visiting the manual
you want to consult.)  Otherwise, it loads and displays the manual.

*** `e' is now bound to `end-of-buffer' rather than to `Info-edit'.
This is for compatibility with the stand-alone Info reader program,
and also because `Info-edit' is a rarely used command that is disabled
by default.

** Mail mode changes (not Message mode)

*** New command M-x mail-add-attachment for adding MIME attachments

*** The command M-x mail-attach-file was renamed to M-x mail-insert-file.
(Its name is misleading, since it has nothing to do with MIME
attachments.)  The old name is now an obsolete alias to the new name.

** MH-E has been updated to MH-E version 8.3.1.
See MH-E-NEWS for details.

** Modula-2 mode provides auto-indentation.

** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.

** nXML mode no longer binds C-RET to `nxml-complete'.
Completion is now performed via `completion-at-point', bound to C-M-i
or M-TAB.  If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the
default), this performs tag completion.

** Org mode has been updated to version 7.8.09.
See ORG-NEWS for details.

** Prolog mode has been completely revamped, with lots of additional
functionality such as more intelligent indentation, electricity,
support for more variants, including Mercury, and a lot more.

** Rmail

*** The command `rmail-epa-decrypt' decrypts OpenPGP data
in the Rmail incoming message.

*** The variable `rmail-message-filter' no longer has any effect.
This change was made in Emacs 23.1 but was not advertised at the time.
Try using `rmail-show-message-hook' instead.

** Shell mode

*** M-x shell prompts for the shell path name if the default directory
is a remote file name and neither the environment variable $ESHELL nor
the variable `explicit-shell-file-name' is set.

*** TAB is now bound to the standard `completion-at-point' command,
which now implements the pcomplete rules for shell command completion.

** SMTPmail

*** SMTPmail now uses encrypted connections (via STARTTLS) by default
if the mail server supports them.  This uses either built-in GnuTLS
support, or the starttls.el library.  Customize `smtpmail-stream-type'
to change this.

*** The variable `smtpmail-auth-credentials' has been removed.
By default, the information is now stored in the file ~/.authinfo.
This was the default value of smtpmail-auth-credentials.  If you had
customized smtpmail-auth-credentials to a list of user names and
passwords, those settings are not used.  During your first connection
to the smtp server, Emacs will prompt for the user name and password,
and offer to save them to ~/.authinfo.  Or you can manually copy the
credentials to ~/.authinfo.  For example, if you had

  (setq smtpmail-auth-credentials
        '(("mail.example.org" 25 "jim" "s!cret")))

then the equivalent line in ~/.authinfo would be

  machine mail.example.org port 25 login jim password s!cret

See the auth-source manual for more information, e.g. on encrypting
the credentials file.

*** The variable `smtpmail-starttls-credentials' has been removed.
If you had that set, you need to put

  machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert"

in your ~/.authinfo file instead.

*** 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',
and `sql-oracle-scan-on'.

*** New options controlling prompting for login parameters.
Each supported product has a custom variable `sql-*-login-params',
which is a list of the parameters to be prompted for before a
connection is established.

*** The command `sql-product-interactive' now takes a prefix argument,
which causes it to prompt for an SQL product.

*** Product-specific SQL interactive commands now take prefix arguments.
These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.),
given a prefix argument, prompt for a name for the SQL interactive
buffer.  This reduces the need for calling `sql-rename-buffer'.

*** SQL interactive modes suppress command continuation prompts, and
replace tabs with spaces.  The first change impacts multiple line SQL
statements entered with C-j between each line, statements yanked into
the buffer and statements sent with `sql-send-*' functions.  The
second prevents the MySQL and Postgres interpreters from listing
object name completions when sent text via `sql-send-*' functions.

*** New command `sql-connect' starts a predefined SQLi session,
using the login parameters from `sql-connection-alist'.

*** New "Save Connection" menu item in SQLi buffers.
This gathers the login params specified for the SQLi session, if it
was not started by a connection, and saves them as a new connection.

*** New commands for listing database objects and details:
sql-list-all and sql-list-table.

*** An API for manipulating SQL product definitions has been added.

** TeX modes

*** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.

** Tramp

*** New inline access method "ksu" (kerberized su).

*** The following access methods are discontinued: "ssh1_old",
"ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".

*** The user option `remote-file-name-inhibit-cache' controls whether
remote file attributes are cached for better performance.

*** The option `ange-ftp-binary-file-name-regexp' has changed its
default value to "".

*** Handlers for `file-selinux-context' and `set-file-selinux-context'
for remote machines which support SELinux.

** New function `url-queue-retrieve', which behaves like url-retrieve,
but with limits (`url-queue-parallel-processes', `url-queue-timeout') on
the degree of parallelism.

** VC and related modes

*** Support for pulling on distributed version control systems.
The command C-x v + (`vc-pull') runs a "pull" operation, if it is
supported (currently with Bzr, Git, and Mercurial), to update the
current branch and working tree.  A prefix argument means to prompt
the user for specifics, e.g. a pull location.

*** `vc-update' is now an alias for `vc-pull'.

*** Support for merging on distributed version control systems.
The command C-x v m (`vc-merge') now runs a "merge" operation, if it
is supported (currently with Bzr, Git, and Mercurial), to merge
changes from another branch into the current one.  It prompts for
specifics, e.g. a merge source.

*** New option `vc-revert-show-diff' controls whether `vc-revert'
shows a diff while querying the user.  It defaults to t.

*** Log entries in some Log View buffers can be toggled to display a
longer description by typing RET (log-view-toggle-entry-display).
This is currently supported for Bzr, Git, and Mercurial (to support
another backend, define a `log-view-expanded-log-entry-function').
In the Log View buffers made by C-x v L (`vc-print-root-log'), you can
use this to display the full log entry for the revision at point.

*** New command `vc-ediff' allows visual comparison of two revisions
of a file similar to `vc-diff', but using ediff backend.

*** The option `vc-initial-comment' was removed in Emacs 23.2, but
this was not advertised at the time.

*** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'.
Since Emacs 23, it has done the same thing as `toggle-read-only', but
this was not advertised at the time.

** Obsolete modes

*** abbrevlist.el

*** erc-hecomplete.el (use erc-pcomplete.el instead)

*** partial-completion-mode (complete.el) is obsolete.
You can get a comparable behavior with:
(setq completion-styles '(partial-completion initials))
(setq completion-pcm-complete-word-inserts-delimiters t)

*** pc-mode.el is obsolete (CUA mode is much more comprehensive).

*** pgg is obsolete (use EasyPG instead).

*** sregex.el is obsolete, since rx.el is a strict superset.

*** s-region.el and pc-select.el are obsolete.
They are superseded by shift-select-mode, enabled by default since 23.1.

*** vc-mcvs.el is obsolete (for lack of a maintainer).

** Miscellaneous

*** The Landmark game is now invoked with `landmark', not `lm'.
Its functions and variables have been similarly renamed.

*** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'.
(This interfered with cua-mode.)

*** f90.el has some support for Fortran 2008 syntax.

*** `copyright-fix-years' can optionally convert consecutive years to ranges.

*** New command `nato-region' converts text to NATO phonetic alphabet.

* New Modes and Packages in Emacs 24.1

** Occur Edit mode applies edits made in *Occur* buffers to the
original buffers.  It is bound to "e" in Occur mode.

** New global minor mode electric-pair-mode.
When enabled, typing an open parenthesis automatically inserts the
matching closing one.

** New global minor mode electric-indent-mode.
When enabled, typing certain characters triggers reindentation.
Major modes wishing to use this can set electric-indent-chars or
electric-indent-functions.

** New global minor mode electric-layout-mode.
When enabled, typing certain characters automatically inserts newlines.
Major modes wishing to use this can set electric-layout-rules.

** tabulated-list.el provides a generic major mode for tabulated data,
from which other modes can be derived.

** pcase.el provides the ML-style pattern matching macro `pcase'.

** secrets.el is an implementation of the Secret Service API, an
interface to password managers like GNOME Keyring or KDE Wallet.  The
Secret Service API requires D-Bus for communication.  The command
`secrets-show-secrets' offers a buffer with a visualization of the
secrets.

** notifications.el provides an implementation of the Desktop
Notifications API.  It requires D-Bus for communication.

** soap-client.el supports access to SOAP web services from Emacs.
soap-inspect.el is an interactive inspector for SOAP WSDL structures.

** New generic mode, xmodmap-generic-mode, for xmodmap files.

** New emacs-lock.el package.
The previous version has been moved to obsolete/old-emacs-lock.el.
Now, there is a proper minor mode `emacs-lock-mode'.  Protection
against exiting Emacs and killing the buffer can be set separately.
The mechanism for automatically turning off protection for buffers
with dead inferior processes has been generalized.

\f
* Incompatible Lisp Changes in Emacs 24.1

** Passing a nil argument to a minor mode function call now ENABLES
the minor mode unconditionally.  This is so that you can write e.g.

 (add-hook 'text-mode-hook 'foo-mode)

to enable foo-mode in Text mode buffers, removing the need for
`turn-on-foo-mode' style functions.  This affects all mode commands
defined by `define-minor-mode'.  If called interactively, the mode
command still toggles the minor mode.

** The return value of `backup-buffer' has changed.
It is now a list of three elements, where the second element is a list
describing the original file's SELinux context.  If Emacs or the
system lacks SELinux support, the context list is (nil nil nil nil).
See "Basic SELinux support" above, under "Changes in Emacs 24.1".

** `char-direction-table' and the `char-direction' function were deleted.
They were buggy and inferior to the new support of bidirectional
editing introduced in Emacs 24.  If you need the bidirectional
properties of a character, use `get-char-code-property' with the last
argument `bidi-class'.

** `copy-directory' now copies the source directory as a subdirectory
of the target directory, if the latter is an existing directory.  The
new optional arg COPY-CONTENTS, if non-nil, makes the function copy
the contents directly into a pre-existing target directory.

** For mouse click input events in the text area, the Y pixel
coordinate in the POSITION list now counts from the top of the text
area, excluding any header line.  Previously, it counted from the top
of the header line.

** Support for "old-style" backquotes, obsolete for 10+ years, has
been further reduced.  Now a backquote not followed by a space is
always treated as a "new-style" backquote.  Please remove all
"old-style" backquotes from your code.  If your code uses backquotes
as documented in the Elisp manual, and compiles without warning, then
you have nothing to do in this regard.  Code not following the
appropriate conventions may fail to compile.

The most common cause of trouble seems to be an old-style backquote
followed by a newline.  Another cause of trouble is vector notation
for key sequence notation: instead of [(control ,)] and [(control ')],
you should write [(control ?,)] and [(control ?')], which will work in
older Emacsen too.

** The macro `eval-at-startup' was removed in Emacs 23.2, but this
was not advertised at the time.  The function `custom-initialize-delay'
replaced all known uses.

** `view-buffer' now treats special mode-class in the same way that
`view-file' has since Emacs 22 (i.e. it won't enable View mode if the
major mode is special).

** Menu and tool bar changes

*** During startup, Emacs no longer adds entries for `menu-bar-lines'
and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'.
With these alist entries omitted, `make-frame' checks the value of the
variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create
a menu-bar or tool-bar, respectively.  If the alist entries are added,
they override the value of `menu-bar-mode'/`tool-bar-mode'.

*** The menu bar bindings's caches are not used any more.
Use (where-is-internal <def> nil t) instead.

** Regions created by mouse dragging are now normal active regions,
similar to those created by shift-selection (see Selection changes
above).  In previous Emacs versions, these regions were delineated by
`mouse-drag-overlay'; that variable has been removed.

** The fourth argument of `filter-buffer-substring' has been removed.
If you want to remove text properties from the final result, simply
pass the result through substring-no-properties.

** cl.el no longer provides `cl-19'.

** The following obsolete functions and aliases have been removed
(the appropriate new function is given in parentheses; "not needed"
means you can just remove all calls to the function in question):

*** `comint-kill-output' (`comint-delete-output')
*** `decompose-composite-char' (`char-to-string')
*** `outline-visible' (`outline-invisible-p')
*** `internal-find-face' (`facep')
*** `internal-get-face' (`facep and check-face')
*** `frame-update-faces' (not needed)
*** `frame-update-face-colors' (`frame-set-background-mode')
*** `x-frob-font-weight' and `x-frob-font-slant' (`make-face-*' functions)
*** `x-make-font-bold and x-make-font-demibold (`make-face-bold')
*** `x-make-font-italic' and `x-make-font-oblique' (`make-face-italic')
*** `x-make-font-bold-italic' (`make-face-bold-italic')
*** `x-make-font-unbold' (`make-face-unbold')
*** `x-make-font-unitalic' (`make-face-unitalic')
*** `mldrag-drag-mode-line' (`mouse-drag-mode-line')
*** `mldrag-drag-vertical-line' (`mouse-drag-vertical-line')
*** `iswitchb-default-keybindings' (`iswitchb-mode')
*** `char-bytes' (== 1)
*** `isearch-return-char' (`isearch-printing-char')
*** `make-local-hook' (not needed)
*** `set-screen-height' (`set-frame-height')
*** `set-screen-width' (`set-frame-width')

** The following obsolete variables and varaliases have been removed
(the appropriate new variable is given in parentheses):

*** `checkdoc-minor-keymap' (`checkdoc-minor-mode-map')
*** `vc-header-alist' (`vc-BACKEND-header')
*** `directory-sep-char' (== ?/)
*** `font-lock-defaults-alist' (`font-lock-defaults')
*** `e' (`float-e').

** The following obsolete files were removed:
sc.el, x-menu.el, rnews.el, rnewspost.el

** The format of the finder-inf.el file has changed, since the Finder
mechanism is now based on the package system.  The variable
`finder-package-info' is replaced by `package--builtins' and
`finder-keywords-hash'.

** When generating autoloads, `update-directory-autoloads' no longer
assumes every inspected file is in your `load-path'.  It instead
generates relative names according to the current `load-path'.

\f
* Lisp changes in Emacs 24.1

** Code can now use lexical scoping by default instead of dynamic scoping.
The `lexical-binding' variable enables lexical scoping for local
variables.  It is typically set via a file-local variable in the first
line of the file, in which case it applies to all the code in that
file.

*** `eval' takes a new optional argument `lexical' to choose the new lexical
binding instead of the old dynamic binding mode.

*** Lexically scoped interpreted functions are represented with a new form
of function value which looks like (closure ENV ARGS &rest BODY).

*** New macro `letrec' to define recursive local functions.

*** `defvar' and `defconst' now mark the variable as special (dynamic).
So do `defcustom' and other forms that call `defvar' as a subroutine.

*** New function `special-variable-p' to check whether a variable is
declared as dynamically bound.

*** The form ((lambda ...) ...) is deprecated.

** An Emacs Lisp testing tool is now included.
Emacs Lisp developers can use this tool to write automated tests for
their code.  See the ERT info manual for details.

** Changes for bidirectional display and editing

*** New function `current-bidi-paragraph-direction'.
This returns the base direction of the paragraph at point.

*** New function `bidi-string-mark-left-to-right'.
Given a string containing characters from right-to-left scripts, this
function returns another string which can be safely inserted into a
buffer, such that any following text will be always displayed to the
right of that string.  (This works by appending an invisible Unicode
"LEFT-TO-RIGHT MARK" character if the argument string might need it.)

This is useful when the buffer has overall left-to-right paragraph
direction and you need to insert a string whose contents are not known
in advance, without disrupting the layout of the line.

** Window changes

*** Window tree functions are accessible in Elisp.
Functions are provided to return the parent, siblings or child windows
of any window including internal windows (windows not associated with a
buffer) in the window tree.

**** New function `window-valid-p' gives non-nil for live and internal
windows.

**** Window manipulation can deal with internal windows.
Many window handling functions like `split-window', `delete-window', or
`delete-other-windows' as well as the window resizing functions can now
act on any window including internal ones.

*** window-total-height/-width vs window-body-height/-width.
The function `window-height' has been renamed to `window-total-height'
and `window-width' has been renamed to `window-body-width'.  The old
names are provided as aliases.  Two new functions `window-total-width'
and `window-body-height' are provided.

*** Window parameters specific to window handling functions.
For each window you can specify a parameter to override the default
behavior of a number of functions like `split-window', `delete-window'
and `delete-other-windows'.  The variable `ignore-window-parameters'
allows to ignore processing such parameters.

*** New semantics of third argument of `split-window'.
The third argument of `split-window' has been renamed to SIDE and can be
set to any of the values 'below, 'right, 'above, or 'left to make the
new window appear on the corresponding side of the window that shall be
split.  Any other value of SIDE will cause `split-window' to split the
window into two side-by-side windows as before.

*** Window resizing functions.
A new standard function for resizing windows called `window-resize' has
been introduced.  This and all other functions for resizing windows no
longer delete any windows when they become too small.

*** Deleting the selected window now selects the most recently selected
live window on that frame instead.

*** `adjust-window-trailing-edge' adjustments.
`adjust-window-trailing-edge' can now deal with fixed-size windows and
is able to resize other windows if a window adjacent to the trailing
edge cannot be shrunk any more.  This makes its behavior more similar to
that of Emacs 21 without compromising, however, its inability to delete
windows which was introduced in Emacs 22.

*** Window-local buffer lists.
Windows now have local buffer lists.  This means that removing a buffer
from display in a window will preferably show the buffer previously
shown in that window with its previous window-start and window-point
positions.  This also means that the same buffer may be automatically
shown twice even if it already appears in another window.

*** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW,
which if non-nil requires the buffer to be displayed in the currently
selected window, signaling an error otherwise.  If nil, another window
can be used, e.g. if the selected one is strongly dedicated.

*** `split-window-vertically' and `split-window-horizontally' renamed
to `split-window-below' and `split-window-right' respectively.
The old names are kept as aliases.

*** Display actions

**** The second arg to `display-buffer' and `pop-to-buffer' is now
named ACTION, and takes a display action of the same form as
`display-buffer-base-action' (see Changes, above).  A non-nil,
non-list value is treated specially, as the old meaning.

**** New variable `display-buffer-overriding-action'.

**** The procedure of `display-buffer' etc. to choose a window is
determined by combining `display-buffer-overriding-action',
`display-buffer-alist', the ACTION arg, `display-buffer-base-action',
and `display-buffer-fallback-action'.  The second and fourth of these
are user-customizable variables.

See the docstring of `display-buffer' for details.

*** New functions `window-state-get' and `window-state-put'.
These functions allow to save and restore the state of an arbitrary
frame or window as an Elisp object.

** Completion

*** New variable `completion-extra-properties' used to specify extra
properties of the current completion:
- :annotate-function, same as the old completion-annotate-function.
- :exit-function, function to call after completion took place.

*** Functions on `completion-at-point-functions' can return any of the
properties valid for `completion-extra-properties'.

*** `completion-annotate-function' is obsolete.

*** New `metadata' method for completion tables.  The metadata thus returned
can specify various details of the data returned by `all-completions':
- `category' is the kind of objects returned (e.g., `buffer', `file', ...),
  used to select a style in completion-category-overrides.
- `annotation-function' to add annotations in *Completions*.
- `display-sort-function' to specify how to sort entries in *Completions*.
- `cycle-sort-function' to specify how to sort entries when cycling.

*** `minibuffer-local-filename-must-match-map' is not used any more.
Instead, the bindings in `minibuffer-local-filename-completion-map'
are combined with `minibuffer-local-must-match-map'.

*** New variable `completing-read-function' allows overriding the
behavior of `completing-read'.

** `glyphless-char-display' can now distinguish between graphical and
text terminal display, via a char-table entry that is a cons cell.

** `pre-command-hook'/`post-command-hook' are not reset to nil on error.
Instead, the offending function is removed.

** New hook types

*** New function `run-hook-wrapped' for running an abnormal hook by
passing the hook functions as arguments to a "wrapping" function.
Like `run-hook-with-args-until-success', it stops at the first
non-nil return value.

*** New macro `with-wrapper-hook' for running an abnormal hook as a
set of "wrapping" filters, similar to around advice.
(A version of this macro was actually added in Emacs 23.2 but was not
advertised at the time.)

** Debugger changes

*** New macro `condition-case-unless-debug' (this was actually added in
Emacs 23.1 as condition-case-no-debug, but not advertised)

*** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised.

*** Variable `stack-trace-on-error' removed.

*** The debugger can now "continue" from an error, which means it will
jump to the error handler as if the debugger had not been invoked
instead of jumping all the way to the top-level.

*** Set `debug-on-event' to enter the debugger on events like SIGUSR1.
This can be useful when `inhibit-quit' is set.

*** 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.

** The new function `server-eval-at' allows evaluation of Lisp forms on
named Emacs server instances.

** `call-process' and `call-process-region' allow a `(:file "file")' spec
to redirect STDOUT to a file.

** The function `format-time-string' now supports the %N directive,
for higher-resolution time stamps.

** New input reading functions

*** New function `read-char-choice' reads a restricted set of
characters, discarding any inputs not inside the set.

*** The command `read-color' now requires a match for a color name
or RGB triplet, instead of signaling an error if the user provides
invalid input.

**** `facemenu-read-color' is now an alias for `read-color'.

** `image-library-alist' is renamed to `dynamic-library-alist'.
The variable is now used to load all kind of supported dynamic libraries,
not just image libraries.  The previous name is still available as an
obsolete alias.

** Syntax parsing changes

*** New variable `syntax-propertize-function'.
This replaces `font-lock-syntactic-keywords' which is now obsolete.
This allows syntax-table properties to be set independently from font-lock:
just call syntax-propertize to make sure the text is propertized.
Together with this new variable come a new hook
syntax-propertize-extend-region-functions, as well as two helper functions:
syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
as-is; and syntax-propertize-rules which provides a new way to specify
syntactic rules.

*** Syntax tables support a new "comment style c" additionally to style b.

** New hook `post-self-insert-hook', run after `self-insert-command'.

** frame-local variables cannot be let-bound any more.

** Major and minor mode changes

*** `set-auto-mode' now respects mode: local variables at the end of files,
as well as those in the -*- line.

*** `prog-mode' is a new major mode from which programming modes
should be derived.

**** `prog-mode-hook' can be used to enable features for programming
modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
on-the-fly spell checking for comments and strings.

*** New hook `change-major-mode-after-body-hook', run by
`run-mode-hooks' just before any other mode hooks.

*** Enabled globalized minor modes can be disabled in specific major modes.
If the global mode is global-FOO-mode, then run (FOO-mode -1) in the
major mode's hook, where FOO-mode toggles the mode on a per-buffer basis.

*** `define-minor-mode' accepts new keywords :variable, :after-hook.

** File-handling changes

*** `delete-file' and `delete-directory' now accept optional arg TRASH.
Trashing is performed if TRASH and `delete-by-moving-to-trash' are
both non-nil.  Interactively, TRASH defaults to t, unless a prefix
argument is supplied (see Trash changes, above).

*** New file predicates: `file-equal-p', `file-in-directory-p'.

** Tool-bars can display separators.
Tool-bar separators are handled like menu separators in menu-bar maps,
i.e. via menu entries of the form `(menu-item "--")'.

** Image API

*** Animated images support (currently animated gifs only).

**** `image-animated-p' returns non-nil if an image can be animated.

**** `image-animate' animates a supplied image spec.

**** `image-animate-timer' returns the timer object for an image that
is being animated.

*** `image-extension-data' has been renamed to `image-metadata'.
The old name is an obsolete alias to the new one.

*** Image mode can view any image type that ImageMagick supports.
This requires Emacs to be built with ImageMagick support.

**** New function `imagemagick-types', defined if ImageMagick support
is enabled, returns a list of image file extensions that your
ImageMagick installation supports.

**** New function `imagemagick-register-types' enables ImageMagick
image types in Image mode and in `create-image' and other helper
functions.

**** New option `imagemagick-types-inhibit' excludes certain
ImageMagick image types from `imagemagick-register-types'.

**** With ImageMagick support, there are extra Image mode commands to
resize and rotate images: `image-transform-fit-to-height',
`image-transform-fit-to-width', `image-transform-set-rotation', and
`image-transform-set-scale'.

** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
passes it to the mail user agent function.  This argument specifies an
action for returning to the caller after finishing with the mail.  For
example, this is used by Rmail to optionally delete a mail window.

** XML and HTML parsing
If Emacs is compiled with libxml2 support, there are two new
functions: `libxml-parse-html-region' (which parses "real world" HTML)
and `libxml-parse-xml-region' (which parses XML).  Both return an
Emacs Lisp parse tree.

** Networking and encryption changes

*** `open-network-stream' can now be used to open an encrypted stream.
It now accepts an optional `:type' parameter for initiating a TLS
connection, directly or via STARTTLS.  To do STARTTLS, additional
parameters (`:end-of-command', `:success', `:capabilities-command')
must also be supplied.

*** New library gnutls.el.
The new function `gnutls-available-p' returns non-nil if Emacs is
built with GnuTLS support.  The main entry points are
`open-gnutls-stream' and `gnutls-negotiate'.  It's easiest to use
these functions through `open-network-stream', because that can
upgrade connections through STARTTLS opportunistically or use plain
SSL, depending on your needs.  For debugging, set `gnutls-log-level'
greater than 0.

*** New primitive `secure-hash' that supports many secure hash algorithms:
md5, sha1, sha2, sha224, sha256, sha384, and sha512.  The lisp library
sha1.el has been removed.  The `sha1' feature is provided by default.

** Isearch

*** New hook `isearch-update-post-hook' that runs in `isearch-update'.

** Progress reporters can now "spin".
The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
now be nil, or omitted.  This makes a "non-numeric" reporter.  Each
time you call `progress-reporter-update' on that progress reporter,
with a nil or omitted VALUE argument, the reporter message is
displayed with a "spinning bar".

** New variable `revert-buffer-in-progress-p' is true while a buffer is
being reverted, even if the buffer has a local `revert-buffer-function'.

** New variables `delayed-warnings-list' and `delayed-warnings-hook'.
If delayed-warnings-list is non-nil, the command loop calls
`delayed-warnings-hook' after `post-command-hook'.  At present, this
is only used by Emacs on some platforms to display warnings during
startup, which might otherwise not be noticed.  This uses the
functions `display-delayed-warnings' and `collapse-delayed-warnings'.

** rx.el has a new `group-n' construct for explicitly numbered groups.

** New function `make-composed-keymap' that constructs a new keymap
from multiple input maps.  You can use this to make a keymap that
inherits from multiple maps, eg:
 (set-keymap-parent newmap (make-composed-keymap othermap parent))

** New function `string-prefix-p'.
(This was actually added in Emacs 23.2 but was not advertised at the time.)

** New reader macro ## that stands for the empty symbol.
This means that the empty symbol can now be read back.  Also, #: by itself
(when not immediately followed by a possible symbol character) stands for
an empty uninterned symbol.

** New math functions `isnan', `copysign', `frexp', `ldexp'.

** The following functions and variables are obsolete:

*** `tooltip-use-echo-area' is obsolete.
Rather than setting this to t, disable Tooltip mode instead.

*** buffer-substring-filters is obsolete.
Use `filter-buffer-substring-functions' instead.

*** `byte-compile-disable-print-circle' is obsolete.

*** `deferred-action-list' and `deferred-action-function' are obsolete.
Use `post-command-hook' instead.

*** `font-lock-maximum-size' is obsolete.

\f
* Changes in Emacs 24.1 on non-free operating systems

** On MS Windows, Emacs warns when using the obsolete init file _emacs,
and also when HOME is set to C:\ by default.

** New configure.bat options

*** --enable-checking builds Emacs with extra runtime checks.

*** --distfiles specifies files to be included in binary distribution.

*** --without-gnutls disables automatic GnuTLS detection.

*** --lib for general library linkage, works with the USER_LIBS build variable.

** New make target `dist' to create binary distribution for MS Windows.

** The Lisp function `w32-default-color-map' is now obsolete.
(It is only used internally in the Emacs C code.)

** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but
reappear on mouse-over.  (Requires OS X 10.6 or later.)

** On Mac OS X, dragging a file into Emacs visits the file, like on
other platforms, rather than inserting its contents into the buffer.
