Please send Emacs bug reports to bug-gnu-emacs@gnu.org.
These provide no new functionality, they just remove the need to edit
lib-src/Makefile by hand in order to use the associated features.
----
-** 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,
* 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.)
+command line arguments, and the EMACS_UNIBYTE environment variable, no
+longer have any effect. (They were declared obsolete in Emacs 23.)
+
+** New command line option `--no-site-lisp' removes site-lisp directories
+from load-path. -Q now implies this.

* Changes in Emacs 24.1
off by customizing x-gtk-use-system-tooltips.
** Lucid menus and dialogs can display antialiased fonts if Emacs is built
-with Xft.
+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.
** An Emacs Lisp package manager is now included.
This is a convenient way to download and install additional packages,
-from elpa.gnu.org.
+from a package repository at elpa.gnu.org.
*** `M-x list-packages' shows a list of packages, which can be
selected for installation.
`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.
+*** 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'.
+
+*** New option `custom-safe-themes' records known-safe theme files.
+If a theme is not in this list, Emacs queries before loading it, and
+offers to save the theme to `custom-safe-themes' automatically. By
+default, all themes included in Emacs are treated as safe.
+
** 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
+replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
+
+** The variable `focus-follows-mouse' now always defaults to nil.
+
\f
* 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.
+
+** The command `just-one-space' (C-SPC), if given a negative argument,
+also deletes newlines around point.
** 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.
+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-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.
+This variable exists only on X; its default value was t in previous
+versions.
-*** `x-select-enable-primary' now defaults to nil.
+**** `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.
+** 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.
+
\f
* Changes in Specialized Modes and Packages in Emacs 24.1
+** The Landmark game is now invoked with `landmark', not `lm'.
+
+** Prolog mode has been completely revamped, with lots of additional
+functionality such as more intelligent indentation, electricty, support for
+more variants, including Mercury, and a lot more.
+
+** 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.
+
+** 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.
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
---
*** 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.
Use the arrow to the left of the option name to toggle visibility.
*** 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.
-
-*** 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.
*** An API for manipulating SQL product definitions has been added.
+** sregex.el is now obsolete, since rx.el is a strict superset.
+
** s-region.el is now declared obsolete, superceded by shift-select-mode
enabled by default in 23.1.
*** 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.
+
** 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.
+
+** Miscellaneous
+
+---
+*** `copyright-fix-years' can optionally convert consecutive years to ranges.
+

* New Modes and Packages in Emacs 24.1
-** New global minor modes electric-pair-mode and electric-indent-mode.
+** New global minor modes electric-pair-mode, electric-indent-mode,
+and electric-layout-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
interface to password managers like GNOME Keyring or KDE Wallet. The
Secret Service API requires D-Bus for communication. The command
\f
* Incompatible Lisp Changes in Emacs 24.1
+** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
+passes it to the mail user agent function. This argument specifies an
+action for returning to the caller after finishing with the mail.
+This is currently used by Rmail to delete a mail window.
+
+** For mouse click input events in the text area, the Y pixel
+coordinate in the POSITION list now counts from the top of the text
+area, excluding any header line. Previously, it counted from the top
+of the header line.
+
+** Remove obsolete name `e' (use `float-e' instead).
+
** A backquote not followed by a space is now always treated as new-style.
** Test for special mode-class was moved from view-file to view-buffer.
** The following files, obsolete since at least Emacs 21.1, have been removed:
sc.el, x-menu.el, rnews.el, rnewspost.el
+** FIXME finder-inf.el changes.
+
\f
* Lisp changes in Emacs 24.1
+** 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
+jumping all the way to the top-level.
+
+** New function `read-char-choice' reads a restricted set of characters,
+discarding any inputs not inside the set.
+
** `image-library-alist' is renamed to `dynamic-library-alist'.
The variable is now used to load all kind of supported dynamic libraries,
not just image libraries. The previous name is still available as an
** New completion style `substring'.
+** `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
+input.
+
+** Tool-bars can display separators.
+Tool-bar separators are handled like menu separators in menu-bar maps,
+i.e. via menu entries of the form `(menu-item "--")'.
+
** Image API
*** When the image type is one of listed in `image-animated-types'
*** 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
+`libxml-parse-html-region' (which will parse "real world" HTML)
+and `libxml-parse-xml-region' (which parses XML). Both return an
Emacs Lisp parse tree.
FIXME: These should be front-ended by xml.el.
