** There is a new configure option --with-crt-dir.
This is only useful if your crt*.o files are in a non-standard location.
+---
+** Emacs can be compiled against 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.
+
+** There is a 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.
+
+---
+** New translation of the Emacs Tutorial in Hebrew is available
+Type `C-u C-h t' to choose it in case your language setup doesn't
+automatically select it.

* Startup Changes in Emacs 24.1
+** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
+command line arguments no longer have any effect. (They were declared
+obsolete in Emacs 23.)
+
\f
* Changes in Emacs 24.1
-** New emacsclient argument --parent-id ID can be used to open a
+** 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.
+*** If emacsclient shuts down as a result of Emacs signalling an
+error, its exit status is 1.
+
** Completion can cycle, depending on completion-cycle-threshold.
** auto-mode-case-fold is now enabled by default.
Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
is taken from the desktop settings.
+** 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. To disable this, 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'.
+
+See the Emacs Lisp Reference Manual for more information.
+
+** 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
+off by customizing x-gtk-use-system-tooltips.
+
** Lucid menus and dialogs can display antialiased fonts if Emacs is built
with Xft.
*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
for remote machines which support SELinux.
+** 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.
+
** New scrolling commands `scroll-up-command' and `scroll-down-command'
(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
of buffer at first key-press (instead moves to top/bottom of buffer)
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.
+define it as a scroll command affected by `scroll-preserve-screen-position'.
** Trash changes
** An Emacs Lisp package manager is now included.
This is a convenient way to download and install additional packages,
-from elpa.gnu.org. `M-x package-list-packages' shows a list of
-packages, which can be selected for installation.
+from 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 and activated
automatically when Emacs starts up. To disable this, set
`package-enable-at-startup' to nil. To change which packages are
loaded, customize `package-load-list'.
+** The user option `remote-file-name-inhibit-cache' controls whether
+the remote file-name cache is used for read access.
+
\f
* Editing Changes in Emacs 24.1
** completion-at-point is now an alias for complete-symbol.
-** mouse-region-delete-keys has been deleted.
+** Deletion changes
+
+*** New option `delete-active-region'.
+If non-nil, C-d, [delete], and DEL delete the region if it is active
+and no prefix argument is given. If set to `kill', these commands
+kill instead.
+
+*** New command `delete-forward-char', bound to C-d and [delete].
+This is meant for interactive use, and obeys `delete-active-region';
+delete-char, meant for Lisp, 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; you
+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 other X applications.
+
+*** `select-active-regions' now defaults to t, so active regions set
+the primary selection.
+
+It also accepts a new value, `lazy', which means to only set the
+primary selection for temporarily active regions (usually made by
+mouse-dragging or shift-selection).
+
+*** `mouse-2' is now bound to `mouse-yank-primary'.
+
+*** `x-select-enable-clipboard' now defaults to t.
+Thus, killing and yanking now use the clipboard (in addition to the
+kill ring).
+
+*** `x-select-enable-primary' now defaults to nil.
+
+*** `mouse-drag-copy-region' now defaults to nil.
+
+*** Support for X cut buffers has been removed.
+
\f
* Changes in Specialized Modes and Packages in Emacs 24.1
+** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
+
+** FIXME: xdg-open for browse-url and reportbug, 2010/08. (Close bug#4546?)
+
** Archive Mode has basic support to browse 7z archives.
+** 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.
+
** In ido-mode, C-v is no longer bound to ido-toggle-vc.
The reason is that this interferes with cua-mode.
(setq completion-pcm-complete-word-inserts-delimiters t)
** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
+
+** Calendar, Diary, and Appt
+
+---
+*** 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.
+
+---
+*** 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
+
** Customize
*** Customize buffers now contain a search field.
*** New key bindings: C-x v I and C-x v O bound to vc-log-incoming and
vc-log-outgoing, respectively.
+*** The 'g' key in VC diff, log, log-incoming and log-outgoing buffers
+reruns the corresponding VC command to compute an up to date version
+of the buffer.
+
*** vc-dir for Bzr supports viewing shelve contents and shelving snapshots.
*** Special markup can be added to log-edit buffers.
**** vc-bzr handles Author:, Date: and Fixes:
**** vc-mtn handles Author: and Date:
+*** Pressing g in a *vc-diff* buffer reruns vc-diff, so it will
+produce an up to date diff.
+
** Directory local variables can apply to file-less buffers.
For example, adding "(diff-mode . ((mode . whitespace)))" to your
.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
** SQL Mode enhancements.
-*** Several variables have been marked as safe local variables.
-The variables `sql-product', `sql-user', `sql-server', and
-`sql-database' can now be safely used as local variables.
+*** Several variables have been marked as safe local variables. The
+variables `sql-product', `sql-user', `sql-server', `sql-database' and
+`sql-port' can now be safely used as local variables.
-*** Added ability to login with a port on MySQL.
+*** `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 servers.
+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.
+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. Preceeding 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. Preceeding the comand 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 be set OFF under
-SQL interactive mode.
+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 comand interpretter for MySQL and Postgres from
supports multithread non-stop debugging and debugging of several
threads simultaneously.
+** D-Bus
+
+*** It is possible now, to access alternative buses than the default
+system or session bus.
+
+** Tramp
+
+*** The following access methods are discontinued: "ssh1_old",
+"ssh2_old", "scp1_old", "scp2_old" and "fish".
+
\f
* New Modes and Packages in Emacs 24.1
+** New global minor modes electric-pair-mode and electric-indent-mode.
+
+** pcase.el provides the ML-style pattern matching macro `pcase'.
+
** smie.el is a package providing a simple generic indentation engine.
** secrets.el is an implementation of the Secret Service API, an
** Passing a nil argument to a minor mode function now turns the mode
ON unconditionally.
+
+** 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'.
+
+** Regions created by mouse dragging are now normal active regions,
+similar to the ones created by shift-selection. In previous Emacs
+versions, these regions were delineated by `mouse-drag-overlay', which
+has now been removed.
+
+** cl.el no longer provides `cl-19'.
+
+** The following functions and aliases, obsolete since at least Emacs 21.1,
+have been removed:
+comint-kill-output, decompose-composite-char, outline-visible,
+internal-find-face, internal-get-face, frame-update-faces,
+frame-update-face-colors, x-frob-font-weight, x-frob-font-slant,
+x-make-font-bold, x-make-font-demibold, x-make-font-unbold
+x-make-font-italic, x-make-font-oblique, x-make-font-unitalic
+x-make-font-bold-italic, mldrag-drag-mode-line, mldrag-drag-vertical-line,
+iswitchb-default-keybindings, char-bytes, isearch-return-char,
+make-local-hook
+
+** The following variables and aliases, obsolete since at least Emacs 21.1,
+have been removed:
+checkdoc-minor-keymap, vc-header-alist, directory-sep-char
+
+** The following files, obsolete since at least Emacs 21.1, have been removed:
+sc.el, x-menu.el, rnews.el, rnewspost.el
+
\f
* Lisp changes in Emacs 24.1
+** New variable syntax-propertize-function to set syntax-table properties.
+Replaces font-lock-syntactic-keywords which are 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.
+
+** New hook post-self-insert-hook run at the end of self-insert-command.
+
++++
+** 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.
** define-minor-mode accepts a new keyword :variable.
-** `delete-file' and `delete-directory now accept optional arg TRASH.
+** `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).
*** `image-extension-data' is renamed to `image-metadata'.
+** XML and HTML parsing
+
+*** If Emacs is compiled with libxml2 support (which is the default),
+two new Emacs Lisp-level functions are defined:
+`xml-parse-html-string-internal' (which will parse "real world" HTML)
+and `xml-parse-string-internal' (which parses XML). Both return an
+Emacs Lisp parse tree.
+
+FIXME: These should be front-ended by xml.el.
+
+** FIXME GnuTLS
+
** Isearch
*** New hook `isearch-update-post-hook' that runs in `isearch-update'.
\f
* Changes in Emacs 24.1 on non-free operating systems
+** New configure.bat option --enable-checking builds emacs with extra
+runtime checks.
+
+** New configure.bat option --distfiles to specify files to be
+ included in binary distribution
+
+** New make target `dist' to create binary disttribution for Windows
+ platform
