* Changes in Emacs 24.1
-** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
-This is handy for minibuffer-only frames, and is also used for the "mouse-1
-pops up *Messages*" feature, which can now easily be changed.
-
-** emacsclient changes
-
-+++
-*** New emacsclient argument --parent-id ID can be used to open a
-client frame in parent X window ID, via XEmbed. This works like the
---parent-id argument to Emacs.
-
-+++
-*** New emacsclient argument -q/--quiet suppresses some status messages.
-
-+++
-*** New emacsclient argument --frame-parameters can be used to set the
-frame parameters of a newly-created graphical frame.
-
-+++
-*** If emacsclient shuts down as a result of Emacs signalling an
-error, its exit status is 1.
+** auto-mode-case-fold is now enabled by default.
** Completion
Instead, the bindings in minibuffer-local-filename-completion-map are combined
with minibuffer-local-must-match-map.
-** auto-mode-case-fold is now enabled by default.
-
** Mail changes
-The default of `send-mail-function' has changed from
-`sendmail-send-it' (on GNU/Linux and other Unix-like systems) or
-`mailclient-send-it' (on Windows) to `sendmail-query-once'. This new
-default will ask the user (once) whether to use the internal smtpmail
-package to send email, or to use the old, external defaults.
+The default of `send-mail-function' is now `sendmail-query-once',
+which asks the user (once) whether to use the smtpmail package to send
+email, or to use the old defaults that rely on external mail
+facilities (`sendmail-send-it' on GNU/Linux and other Unix-like
+systems, and `mailclient-send-it' on Windows).
-** smtpmail changes
+*** smtpmail changes
-*** smtpmail has been largely rewritten to upgrade to STARTTLS if
-possible, and uses the auth-source framework for getting credentials.
-The rewrite should be largely compatible with previous versions of
-smtpmail, but there are two major incompatibilities:
+**** smtpmail now uses encrypted connections (via STARTTLS) if the
+mail server supports them. It also uses the auth-source framework for
+getting credentials.
-*** `smtpmail-auth-credentials' no longer exists. That variable used
-to be be either ~/.authinfo (in which case you won't see any
-difference), but if it were a direct list of user names and passwords,
-it will be ignored, and you will be prompted for the user name and the
-password instead. They will then be saved to ~/.authinfo.
+**** The variable `smtpmail-auth-credentials' has been removed.
+That variable used to have the default value "~/.authinfo", in which
+case you won't see any difference. But if you changed it to be a list
+of user names and passwords, that setting is now ignored; you will be
+prompted for the user name and the password, which will then be saved
+to ~/.authinfo.
-If you wish to copy over all the credentials from
-`smtpmail-auth-credentials' to your ~/.authinfo file manually, instead
-of letting smtpmail prompt you for these values, that's also possible.
+You can also manually copy the credentials to your ~/.authinfo file.
+For example, if you had
-If you had, for instance,
-
-(setq smtpmail-auth-credentials
- '(("mail.example.org" 25 "jim" "s!cret")))
+ (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
+ machine mail.example.org port 25 login jim password s!cret
+
+**** The variable `smtpmail-starttls-credentials' has been removed.
-*** Similarly, `smtpmail-starttls-credentials' no longer exists. If
-you had that set, then then you need to put
+If you had that set, then then you need to put
-machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert

+ machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert"
in your ~/.authinfo file instead.
+** Emacs server and client changes
+
+*** New option `server-port' specifies the port on which the Emacs
+server should listen.
++++
+*** New emacsclient argument -q/--quiet suppresses some status messages.
++++
+*** New emacsclient argument --frame-parameters can be used to set the
+frame parameters of a newly-created graphical frame.
++++
+*** If emacsclient shuts down as a result of Emacs signalling 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.
-See the node "Bidirectional Editing" in the Emacs Manual for some
-additional documentation.
+Right-to-left (RTL) text is displayed in a right-to-left direction.
+This display reordering is a "Full bidirectionality" class
+implementation of the Unicode Bidirectional Algorithm. Buffers with
+no right-to-left (RTL) text should look exactly the same as before.
-To turn this off in any given buffer, set the buffer-local variable
-`bidi-display-reordering' to a nil value. The default is t. For text
-that includes no right-to-left characters, the result of reordering
-looks exactly as it did in previous versions, i.e. there's no
-reordering at all.
+For more information, see the node "Bidirectional Editing" in the
+Emacs Manual.
-The buffer-local variable `bidi-paragraph-direction', if non-nil,
-forces each paragraph in the buffer to have its base direction
-according to the value of this variable. Possible values are
-`right-to-left' and `left-to-right'. If the value is nil (the
-default), Emacs determines the base direction of each paragraph from
-its text, as specified by the Unicode Bidirectional Algorithm.
-
-The function `current-bidi-paragraph-direction' returns the actual
-value of paragraph base direction at point.
++++
+**** New buffer-local variable `bidi-display-reordering'.
+To disable display reordering in any given buffer, change this to nil.

-*** Enhanced support for characters that have no glyphs in available fonts.
-If a character has no glyphs in any of the available fonts, Emacs by
-default will display it either as a hexadecimal code in a box or as a
+*** Enhanced support for characters with no glyphs in available fonts.
+If a character has no glyphs in any of the available fonts, Emacs
+normally displays it either as a hexadecimal code in a box or as a
thin 1-pixel space. In addition to these two methods, Emacs can
display these characters as empty box, as an acronym, or not display
them at all. To change how these characters are displayed, customize
the variable `glyphless-char-display-control'.
-On character terminals these methods are used for characters that

+*** GTK tool bars can be placed on the left/right or top/bottom 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.
-** ImageMagick support.
-It is now possible to use the ImageMagick library to load many new
-image formats in Emacs. By default, Emacs links with the ImageMagick
-libraries if they are present at build time. This needs ImageMagick
-6.2.8 or newer (versions newer than 6.0.7 _may_ work but have not been
-tested). To disable ImageMagick support, use the configure option
-`--without-imagemagick'.
-
-The new function `imagemagick-types' returns a list of image file
-extensions that your installation of ImageMagick supports. The
-function `imagemagick-register-types' enables ImageMagick support for
-these image types, minus those listed in `imagemagick-types-inhibit'.
+*** The colors for selected text (the region face) are taken from the GTK
+theme when Emacs is built with GTK.
-See the Emacs Lisp Reference Manual for more information.
+*** Emacs uses GTK tooltips by default if built with GTK. You can turn that
+off by customizing x-gtk-use-system-tooltips.
** New basic faces `error', `warning', `success' are available to
highlight strings that indicate failure, caution or successful operation.
-** The 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 turn that

-
** Lucid menus and dialogs can display antialiased fonts if Emacs is built
with Xft. To change font, use the X resource font, for example:
Emacs.pane.menubar.font: Courier-12
** The function format-time-string now supports the %N directive, for
higher-resolution time stamps.
-** The function kill-emacs is now run upon receipt of the signals SIGTERM
-and SIGHUP, and upon SIGINT in batch mode.
+** Changes for exiting Emacs
+
+*** The function kill-emacs is now run upon receipt of the signals
+SIGTERM and SIGHUP, and upon SIGINT in batch mode.
-** kill-emacs-hook is now also run in batch mode.
+*** kill-emacs-hook is now also run in batch mode.
If you have code that adds something to kill-emacs-hook, you should
consider if it is still appropriate to add it in the noninteractive case.
-** New scrolling commands `scroll-up-command' and `scroll-down-command'
+** 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 move to top/bottom of buffer)
when a new variable `scroll-error-top-bottom' is non-nil.
-** New scrolling commands `scroll-up-line' and `scroll-down-line'
+*** 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
+*** 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,
+*** 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.
+*** ``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
`package-enable-at-startup' to nil. To change which packages are
loaded, customize `package-load-list'.
-** 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.
-
** Custom Themes
*** `M-x customize-themes' lists Custom themes which can be enabled.
** The user option `remote-file-name-inhibit-cache' controls whether
the remote file-name cache is used for read access.
+** File- and directory-local variable changes
+++
-** The use of a "mode: minor" specification in a file local variables section
-to enable a minor-mode is deprecated. Instead, use "eval: (minor-mode 1)".
+*** 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.
-** The standalone programs lib-src/digest-doc and sorted-doc have been
-replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
+*** 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.
----
-** The standalone program `fakemail' has been removed.
-If you need it, feedmail.el ought to provide a superset of the functionality.
++++
+*** Using "mode: MINOR-MODE" to enable a minor mode is deprecated.
+Instead, use "eval: (minor-mode 1)".
+++
** The variable `focus-follows-mouse' now always defaults to nil.
*** `menu-bar-select-buffer-function' lets you choose another operation
instead of `switch-to-buffer' when selecting an item in the Buffers menu.
+** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
+This is handy for minibuffer-only frames, and is also used for the "mouse-1

-`browse-url-mailto-function', which defaults to `browse-url-mail'.
-
-** `url-queue-retrieve' downloads web pages asynchronously, but allow
-controlling the degree of parallelism.
-
-** Directory local variables can apply to file-less buffers, in certain modes
-(eg dired, vc-dir, log-edit). For example, adding
-"(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file,
-will turn on `whitespace-mode' for *vc-diff* buffers. Modes should
-call `hack-dir-local-variables-non-file-buffer' to support this.
-
-+++
-** You can prevent directory local variables from applying to subdirectories.
-Add an element (subdirs . nil) to the alist portion of any variables
-settings to indicate said section should not be applied to subdirectories.
-
-** ERC changes
-
-*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
-If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
-successful NickServ identification, or after `erc-autojoin-delay'
-seconds. The default value, 'ident, means to autojoin immediately
-after connecting.
-
-*** 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 is a directory named
-"eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
-exists, that is used instead.
-
-** In ido-mode, C-v is no longer bound to ido-toggle-vc.

** Calendar, Diary, and Appt
+++
*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
view-diary-entries, list-diary-entries, show-all-diary-entries
+** CC Mode (C, C++, etc.)
+
+*** New feature to "guess" the style in an existing buffer.

*** The color widget now has a "Choose" button, which allows you to
choose a color via list-colors-display.
+** D-Bus
+
+*** It is possible now, to access alternative buses than the default
+system or session bus.
+
+*** dbus-register-{service,method,property}
+The -method and -property functions do not automatically register
+names anymore.
+
+The new function dbus-register-service registers a service known name
+on a D-Bus without simultaneously registering a property or a method.
+
** Dired-x
*** dired-jump and dired-jump-other-window called with a prefix argument
*** The `dired local variables' feature provided by Dired-x is obsolete.
The standard directory local variables feature replaces it.
-** SQL Mode enhancements.
+** ERC changes
-*** `sql-dialect' is a synonym for `sql-product'.
-
-*** Added ability to login with a port on MySQL and Postgres.
-The custom variable `sql-port' can be specified for connection to
-MySQL or Postgres servers. By default, the port is not listed in
-either login parameter, but will be added to the command line if set
-to a non-zero value.
-
-*** Dynamic selection of product in an SQL interactive session.
-If you use `sql-product-interactive' to start an SQL interactive
-session it uses the current value of `sql-product'. Preceding the
-invocation with C-u will force it to ask for the product before
-creating the session.
-
-*** Renaming a SQL interactive buffer when it is created.
-Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
-`sql-mysql', etc.) with C-u will force a new interactive session to be
-started and will prompt for the new name. This will reduce the need
-for `sql-rename-buffer' is most common use cases.
-
-*** Command continuation prompts in SQL interactive mode are suppressed.
-Multiple line commands in SQL interactive mode, generate command
-continuation prompts which needlessly confuse the output. These
-prompts are now filtered out from the output. This 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.
-
-*** Custom variables control 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.
+*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
+If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
+successful NickServ identification, or after `erc-autojoin-delay'
+seconds. The default value, 'ident, means to autojoin immediately
+after connecting.
+
+*** 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.
-The lists consist of the following five tokens: `user', `password',
-`database', `server', and `port'. The order in which they appear is
-the order in which they are prompted. The tokens symbols can be
-replaced by a sublist starting with the token and followed by a plist
-which control the prompting for values. The tokens `user',
-`database', and `server' each can take a property of :default which
-specifies the value to be used if no value is entered. The
-`database', `server', and `port' tokens handle the :completion
-property which restricts the entry to either one of the values in the
-list or to one of the values returned by the function provided as the
-property value. The `database' and `server' tokens also accept the
-:file property whose value is a regexp to identify useful file names.
-
- (user :default DEF)
- (database :default DEF
- :file FILEPAT
- :completion COMPLETE)
- (server :default DEF
- :file FILEPAT
- :completion COMPLETE)
-
-The FILEPAT when :file is specified is a regexp that will match valid
-file names (without the directory portion). Generally these strings
-will be of the form ".+\.SUF" where SUF is the desired file suffix.
-
-When :completion is specified, the COMPLETE corresponds to the
-PREDICATE argument to the `completing-read' function (a list of
-possible values or a function returning such a list).
-
-*** Added `sql-connection-alist' to record login parameter values.
-An alist for recording different username, database and server
-values. If there are multiple databases that you connect to the
-parameters needed can be stored in this alist.
-
-For example, the following might be set in the user's init.el:
-
- (setq sql-connection-alist
- '((dev (sql-product 'sqlite)
- (sql-database "/home/mmaug/dev.db"))
- (prd (sql-product 'oracle)
- (sql-user "mmaug")
- (sql-database "iprd2a"))))
-
-This defines two connections named "dev" and "prd".
-
-*** Added `sql-connect' to use predefined connections.
-Sets the login parameters based on the values in the
-`sql-connection-alist' and start a SQL interactive session. Any
-values specified in the connection will not be prompted for.
-
-In the example above, if the user were to invoke M-x sql-connect, they
-would be prompted for the connection. The user can respond with
-either "dev" or "prd". The "dev" connection would connect to the
-SQLite database without prompting; the "prd" connection would prompt
-for the users password and then connect to the Oracle database.
-
-**** Added SQL->Start... submenu when connections are defined.
-When connections have been defined, there is a submenu available that
-allows the user to select one to start a SQLi session. The "Start
-SQLi Session" item moves to the "Start..." submenu when cnnections
-have been defined.
-
-**** Added "Save Connection" menu item in SQLi buffers.
-When a SQLi session is not started by a connection then
-`sql-save-connection' will gather the login params specified for the
-session and save them as a new connection.
-
-*** List database objects and details.
-Once a SQL interactive session has been started, you can get a list of
-the objects in the database and see details of those objects. The
-objects shown and the details available are product specific.
-
-**** List all objects.
-Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
-objects" will list all the objects in the database. At a minimum it
-lists the tables and views in the database. Preceding the command by
-universal argument may provide additional details or extend the
-listing to include other schemas objects. The list will appear in a
-separate window in view-mode.
-
-**** List Table details.
-Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
-details" will ask for the name of a database table or view and display
-the list of columns in the relation. Preceding the command with the
-universal argument may provide additional details about each column.
-The list will appear in a separate window in view-mode.
-
-*** Added option `sql-send-terminator'.
-When set makes sure that each command sent with `sql-send-*' commands
-are properly terminated and submitted to the SQL processor.
-
-*** Added option `sql-oracle-scan-on'.
-When set commands sent to Oracle's SQL*Plus are scanned for strings
-starting with an ampersand and the user is asked for replacement text.
-In general, the SQL*Plus option SCAN should always be set OFF under
-SQL interactive mode and this option used in its place.
-
-*** SQL interactive mode will replace tabs with spaces.
-This prevents the command interpreter for MySQL and Postgres from
-listing object name completions when being sent text via
-`sql-send-*' functions.
+** Eshell changes
-*** An API for manipulating SQL product definitions has been added.
+*** The default value of eshell-directory-name is a directory named
+"eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
+exists, that is used instead.
+
+** gdb-mi
+
+*** GDB User Interface migrated to GDB Machine Interface and now
+supports multithread non-stop debugging and debugging of several
+threads simultaneously.
+
+** In ido-mode, C-v is no longer bound to ido-toggle-vc.
+The reason is that this interferes with cua-mode.
** Image mode
*** Option `image-animate-loop', if non-nil, loops the animation.
If nil, `image-toggle-animation' plays the animation once.
-** sregex.el is now obsolete, since rx.el is a strict superset.
+** Info
-** s-region.el and pc-select are now declared obsolete,
-superseded by shift-select-mode enabled by default in 23.1.
-** pc-mode.el is also declared obsolete.
-** gdb-mi
+*** New command `info-display-manual' displays an Info manual
+specified by its name. If that manual is already visited in some Info
+buffer within the current session, the command will display that
+buffer. Otherwise, it will load the manual and display it. 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.
-*** GDB User Interface migrated to GDB Machine Interface and now
-supports multithread non-stop debugging and debugging of several
-threads simultaneously.
+** The Landmark game is now invoked with `landmark', not `lm'.
-** D-Bus
+** MH-E has been upgraded to MH-E version 8.2.93.
+See MH-E-NEWS for details.
-*** It is possible now, to access alternative buses than the default
-system or session bus.
+** Modula-2 mode provides auto-indentation.
-*** dbus-register-{service,method,property}
-The -method and -property functions do not automatically register
-names anymore.
+** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
-The new function dbus-register-service registers a service known name
-on a D-Bus without simultaneously registering a property or a method.
+** 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.
+
+** shell-mode can track your cwd by reading it from your prompt.
+Just set shell-dir-cookie-re to an appropriate regexp.
+
+** SQL Mode enhancements.
+
+*** `sql-dialect' is an alias for `sql-product'.
+
+*** New variable `sql-port' specifies the port number for connecting
+to a MySQL or Postgres server.
+
+*** The command `sql-product-interactive' now takes a prefix argument,
+which causes it to prompt for an SQL product instead of the current
+value of `sql-product'.
+
+*** Product-specific SQL interactive commands now take prefix args.
+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 change prevents the MySQL and Postgres interpreters from
+listing object name completions when sent text via `sql-send-*'
+functions.
+
+*** New custom variables control 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.
+
+*** New variable `sql-connection-alist' for login parameter values.
+This can be used to store different username, database and server
+values. Connections defined in this variable appear in the submenu
+SQL->Start... for making new SQLi sessions.
+
+*** 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.
+
+*** Commands for listing database objects and details.
+In an SQLi session, you can get a list of objects in the database.
+The contents of these lists are product specific.
+
+**** `C-c C-l a' or the "SQL->List all objects" menu item
+lists all the objects in the database. With a prefix argument, it
+displays additional details or extend the listing to include other
+schemas objects.
+
+**** `C-c C-l t' or the "SQL->List Table details" menu item
+prompts for the name of a database table or view and displays the list
+of columns in the relation. With a prefix argument, it displays
+additional details about each column.
+
+*** New options `sql-send-terminator' and `sql-oracle-scan-on'.
+
+*** 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
*** The option `ange-ftp-binary-file-name-regexp' has changed its
default value to "".
-** Rmail
-
-*** The command `rmail-epa-decrypt' decrypts OpenPGP data
-in the Rmail incoming message.
+** `url-queue-retrieve' downloads web pages asynchronously, but allow
+controlling the degree of parallelism.
** VC and related modes
*** New command `vc-ediff' allows visual comparison of two revisions
of a file similar to `vc-diff', but using ediff backend.
-** CC Mode (C, C++, etc.)
+** FIXME: xdg-open for browse-url and reportbug, 2010/08.
-*** New feature to "guess" the style in an existing buffer.
+** Obsolete modes
+
+*** partial-completion-mode 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.
+
+*** sregex.el is obsolete, since rx.el is a strict superset.
+
+*** s-region.el and pc-select are obsolete.
+They are superseded by shift-select-mode enabled by default in 23.1.
** Miscellaneous
*** New command `nato-region' converts text to NATO phonetic alphabet.
-*** The new command `info-display-manual' will display an Info manual
-specified by its name. If that manual is already visited in some Info
-buffer within the current session, the command will display that
-buffer. Otherwise, it will load the manual and display it. 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.

* Lisp changes in Emacs 24.1
+** Code can now use lexical scoping by default instead of dynamic scoping.
+The `lexical-binding' variable lets code use lexical scoping for local
+variables. It is typically set via file-local variables, 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.
+
+*** New function `special-variable-p' to check whether a variable is
+declared as dynamically bound.
+
+** 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 actual value of paragraph base direction at point.
+
++++
+*** New function `bidi-string-mark-left-to-right'.
+Given a string containing right-to-left (RTL) script, this function
+returns another string which can be safely inserted into a buffer as a
+distinct RTL "segment", without causing any following text to be
+displayed as RTL. (This is done by appending a Unicode "left-to-right
+mark" character.)
+
+This is useful when the buffer has overall left-to-right (LTR)
+paragraph direction and you need to insert a string whose contents and
+directionality are not known in advance.
+
** Window changes
*** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW,
*** FIXME: buffer-display-alist changes
** Completion
+
*** New variable completion-extra-properties used to specify extra properties
of the current completion:
- :annotate-function, same as the old completion-annotate-function.
parameters (`:end-of-command', `:success', `:capabilities-command')
must also be supplied.
-** Code can now use lexical scoping by default instead of dynamic scoping.

** pre/post-command-hook are not reset to nil upon error.
Instead, the offending function is removed.
** `call-process' allows a `(:file "file")' spec to redirect STDOUT to
a file.
-** byte-compile-disable-print-circle is obsolete.
-** deferred-action-list and deferred-action-function are obsolete.
** Removed the stack-trace-on-error variable.
Also 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
+++
** Syntax tables support a new "comment style c" additionally to style b.
+
** frame-local variables cannot be let-bound any more.
+
** prog-mode is a new major-mode meant to be the parent of programming mode.
The prog-mode-hook it defines can be used to enable features for
programming modes. For example:
(add-hook 'prog-mode-hook 'flyspell-prog-mode)
enables on the fly spell checking for comments and strings for
programming modes.
+
** define-minor-mode accepts a new keyword :variable.
** `delete-file' and `delete-directory' now accept optional arg TRASH.
both non-nil. Interactively, TRASH defaults to t, unless a prefix
argument is supplied (see Trash changes, above).
-** buffer-substring-filters is obsoleted by filter-buffer-substring-functions.
-
** `facemenu-read-color' is now an alias for `read-color'.
The command `read-color' now requires a match for a color name or RGB
triplet, instead of signalling an error if the user provides a invalid
*** `image-extension-data' is renamed to `image-metadata'.
+*** If Emacs is compiled with ImageMagick support (see Startup
+Changes), the function `imagemagick-types' returns a list of image
+file extensions that your installation of ImageMagick supports. The
+function `imagemagick-register-types' enables ImageMagick support for
+these image types, minus those listed in `imagemagick-types-inhibit'.
+
+See the Emacs Lisp Reference Manual for more information.
+
** XML and HTML parsing
*** If Emacs is compiled with libxml2 support (which is the default),
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.
+
+** Obsolete functions and variables
+
+*** 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.
