+with Xft. To change font, use X resource faceName, for example:
+Emacs.pane.menubar.faceName: Courier-12
+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.

+
+*** `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.

-delete-char, meant for Lisp, does not obey `delete-active-region'.
+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.
** 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.
+
+*** mouse-2 is now bound to `mouse-yank-primary', which pastes from
+the primary selection regardless of the contents of the kill-ring.
-*** `select-active-regions' now defaults to t, so active regions set
-the primary selection.
+*** 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.
-It also accepts a new value, `lazy', which means to only set the
+*** 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.
-Thus, killing and yanking now use the clipboard (in addition to the
-kill ring).
+**** `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.
+**** `x-select-enable-primary' now defaults to nil.
+This variable exists only on X; its default value was t in previous
+versions.
-*** `mouse-drag-copy-region' now defaults to nil.
+**** `mouse-drag-copy-region' 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.
*** Support for X cut buffers has been removed.

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.
+
** In ido-mode, C-v is no longer bound to ido-toggle-vc.
The reason is that this interferes with cua-mode.
** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
+** server can listen on a specific port using the server-port option.
+
+** 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.
The search is performed using `customize-apropos'.
-To turn off the search field, set custom-search-field to nil .
+To turn off the search field, set custom-search-field to nil.
*** Custom options now start out hidden if at their default values.

*** dired-jump and dired-jump-other-window called with a prefix argument
read a file name from the minibuffer instead of using buffer-file-name.
-** 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.
-
-**** vc-git handles Author: and Date:
-**** vc-hg handles Author: and Date:
-**** 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-dialect' is a synonym for `sql-product'.
-*** 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
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
`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.
