+** 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'.

+Set faceName to none and use font to use the old X fonts.
+
++++
+** 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
+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
+cannot be encoded by the `terminal-coding-system'.
+
+** On graphical displays, the mode-line no longer ends in dashes.
** Basic SELinux support has been added.
This requires Emacs to be linked with libselinux at build time.
*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
for remote machines which support SELinux.

+*** 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'.
+** Custom Themes
+
+*** `M-x customize-themes' lists Custom themes which can be enabled.
+
+*** New option `custom-theme-load-path' is the load path for themes.
+Emacs no longer looks for custom themes in `load-path'. The default
+is to search in `custom-theme-directory', followed by a built-in theme
+directory named "themes/" in `data-directory'.
+
+** The user option `remote-file-name-inhibit-cache' controls whether
+the remote file-name cache is used for read access.
+
+** The standalone programs lib-src/digest-doc and sorted-doc have been

Apart from obeying `delete-active-region', its behavior is unchanged.
** Selection changes.
The default handling of clipboard and primary selections has been
-changed to conform with other X applications.
+changed to conform with other X applications. The exact changes are
+described below; in short, mouse commands to select and paste text now
+use the primary selection, while all other commands for killing and
+yanking text now use the clipboard.
+
+*** Merely selecting text (e.g. with drag-mouse-1) does not add it to
+the kill-ring. On systems with a primary selection separate from the
+clipboard (such as X), the selected text is put in the primary
+selection.
-*** `select-active-regions' now defaults to t, so active regions set
-the primary selection.
+*** mouse-2 is now bound to `mouse-yank-primary', which pastes from
+the primary selection regardless of the contents of the kill-ring.
-It also accepts a new value, `lazy', which means to only set the
+*** Commands that kill text or copy it to the kill-ring (M-w, C-w,
+C-k, etc.) also put the killed text into the clipboard. This change
+also means that the "Copy", "Cut", and "Paste" items in the "Edit"
+menu are now exactly equivalent to, respectively M-w, C-w, and C-y.
+
+*** Yank commands, such as C-y and M-y, retrieve text from the
+clipboard if it is available.
+
+*** The above changes are reflected in the following new defaults:
+
+**** `select-active-regions' now defaults to t.
+It also accepts a new value, `only', 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'.
+**** `mouse-2' is now bound to `mouse-yank-primary'.
+Previously, it was bound to `mouse-yank-at-click' (which is now
+unbound by default).
+
+**** `x-select-enable-clipboard' now defaults to t on all platforms.
+Note that this variable was already non-nil by default on MS-Windows,
+which does not support the primary selection between applications.
+
+**** `x-select-enable-primary' now defaults to nil.
+This variable exists only on X; its default value was t in previous
+versions.
-*** `x-select-enable-clipboard' now defaults to t.
-Thus, killing and yanking now use the clipboard (in addition to the
-kill ring).
+**** `mouse-drag-copy-region' now defaults to nil.
-*** `x-select-enable-primary' now defaults to nil.
+*** To return to the previous behavior, where mouse commands use the
+clipboard, change `mouse-drag-copy-region' and (on X only)
+`x-select-enable-primary' to t. If you don't want Emacs to put the
+text into the clipboard, only to the primary selection, additionally
+set `x-select-enable-clipboard' to nil.
-*** `mouse-drag-copy-region' now defaults to nil.
+*** Support for X cut buffers has been removed.

-** VC and related modes
-
-*** New VC commands: vc-log-incoming, vc-log-outgoing, vc-find-conflicted-file.
-
-**** vc-log-incoming for Git runs "git fetch" so that the necessary
-data is available locally.
-
-**** vc-log-incoming and vc-log-outgoing for Git require version 1.7 (or newer).
-
-*** New key bindings: C-x v I and C-x v O bound to vc-log-incoming and
-vc-log-outgoing, respectively.
-
-*** vc-dir for Bzr supports viewing shelve contents and shelving snapshots.
-
-*** Special markup can be added to log-edit buffers.
-The log-edit buffers are expected to have a format similar to email messages
-with headers of the form:
- Author: <author of this change>
- Summary: <one line summary of this change>
- Fixes: <reference to the bug fixed by this change>
-Some backends handle some of those headers specially, but any unknown header
-is just left as is in the message, so it is not lost.

** 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.
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.

+*** 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
which is a list of the parameters to be prompted for before a
connection is established.
-By default, the value of the parameter is simply prompted for. For
-`server' and `database', they can be specified in a list as shown
-below:
-
- (server :file ARG)
- (database :file ARG)
- (server :completion ARG)
- (database :completion ARG)
-
-The ARG 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 ARG corresponds to the PREDICATE
-argument to the `completing-read' function (a list of possible values
-or a function returning such a list).
+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
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.
`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.

* Lisp changes in Emacs 24.1
+** `image-library-alist' is renamed to `dynamic-library-alist'.
+The variable is now used to load all kind of supported dynamic libraries,
