These provide no new functionality, they just remove the need to edit
lib-src/Makefile by hand in order to use the associated features.

* Changes in Emacs 24.1
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.
** An Emacs Lisp package manager is now included.
This is a convenient way to download and install additional packages,
-from elpa.gnu.org.

* Editing Changes in Emacs 24.1
-** completion-at-point is now an alias for complete-symbol.
++++
+** There is a new command `count-words-region', which does what you expect.
+
+** completion-at-point now handles tags and semantic completion.
+
+** The default value of `backup-by-copying-when-mismatch' is now t.
** Deletion changes
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'.
+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.
-
-The new behavior is that by default Emacs does not put selected text
-into the clipboard, and does not add it to kill-ring, merely because
-the text was selected. Only commands that kill text or copy it to the
-kill-ring (C-w, M-w, C-k, etc.) put the killed text into the
-clipboard. Selected text is put into the primary selection (on
-systems, such as X, that support the primary selection separately from
-the clipboard).
-
-Similarly, Emacs by default does not retrieve text from the clipboard
-when the mouse (e.g., mouse-2) is used for pasting text selected in
-another application. Mouse commands that paste text retrieve text
-from the primary selection, on systems that support it separately from
-the clipboard. Text from the clipboard is retrieved only by C-y, M-y
-and other commands that yank text from the kill-ring.
-
-In other words, the default behavior is that mouse gestures that
-select and paste text work with the primary selection (on X), while
-keyboard commands that kill/copy and paste text work with the
-clipboard.
-
-This change also means that the "Copy", "Cut", and "Paste" items of
-the menu-bar "Edit" menu are now exactly equivalent to, respectively
-M-w, C-w, and C-y.
-
-To get back the previous behavior, whereby mouse gestures set the
-clipboard and retrieve text from there, customize the variables
-`mouse-drag-copy-region' and (on X only) `x-select-enable-primary' to
-non-nil values. If you don't want Emacs to put the text into the
-clipboard, only to the primary selection, additionally customize
-`x-select-enable-clipboard' to nil.
-
-These changes in the default behavior are reflected in the default
-values of several variables:
-
-*** `select-active-regions' now defaults to t, so active regions set
-the primary selection. It was nil in previous versions.
+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.
+*** 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.
-Thus, killing and yanking now use the clipboard (in addition to the
-kill ring). 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-clipboard' now defaults to t on all platforms.

+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.
-Its previous default value was t.
+**** `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.
+** New command `rectangle-number-lines', bound to `C-x r N', numbers
+the lines in the current rectangle. With an prefix argument, this
+prompts for a number to count from and for a format string.

* Changes in Specialized Modes and Packages in Emacs 24.1
+** shell-mode can track your cwd by reading it from your prompt.
+Just set shell-dir-cookie-re to an appropriate regexp.
+
+** Modula-2 mode provides auto-indentation.

** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
** FIXME: xdg-open for browse-url and reportbug, 2010/08.
** Archive Mode has basic support to browse 7z archives.
+** browse-url has gotten a new variable that is used for mailto: URLs,
+ `browse-url-mailto-function', which defaults to `browse-url-mail'.
+
** ERC changes
*** New vars `erc-autojoin-timing' and `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.
+
** In ido-mode, C-v is no longer bound to ido-toggle-vc.
The reason is that this interferes with cua-mode.
*** Customize buffers now contain a search field.
The search is performed using `customize-apropos'.

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.
-
-*** 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.
-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.
** Tramp
+*** There exists a new inline access method "ksu" (kerberized su).
+
*** The following access methods are discontinued: "ssh1_old",
"ssh2_old", "scp1_old", "scp2_old" and "fish".
+** VC and related modes
+
+*** Support for pulling on distributed version control systems.
+The vc-update command now runs a "pull" operation, if it is supported.
+This updates the current branch from upstream. A prefix argument
+means to prompt the user for command specifics, e.g. a pull location.
+
+**** vc-pull is an alias for vc-update.
+
+**** Currently supported by Bzr.
+
+*** Support for merging on distributed version control systems.
+The vc-merge command now runs a "merge" operation, if it is supported.
+This merges another branch into the current one. A prefix argument
+means to prompt the user for command specifics, e.g. a merge location.
+
+**** Currently supported by Bzr.
