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
*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
for remote machines which support SELinux.
++++
+** The function format-time-string now supports the %N directive, for
+higher-resolution time stamps.
+
** The function kill-emacs is now run upon receipt of the signals SIGTERM
and SIGHUP, and upon SIGINT in batch mode.
`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.
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.

* Editing Changes in Emacs 24.1
** Selection changes.
-The default handling of clipboard and primary selections has been
-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.
+The default handling of clipboard and primary selections was changed
+to conform with modern X applications. In short, most commands for
+killing and yanking text now use the clipboard, while mouse commands
+use the primary selection.
-*** 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.
+In the following, we provide a list of these changes, followed by a
+list of steps to get the old behavior back if you prefer that.
-*** mouse-2 is now bound to `mouse-yank-primary', which pastes from
-the primary selection regardless of the contents of the kill-ring.
+*** `mouse-drag-copy-region' now defaults to nil.
+*** `select-active-regions' now defaults to t.
+Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
+the kill-ring. The selected text is put in the primary selection, if
+the system possesses a separate primary selection facility (e.g. X).
-*** 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.
+**** `select-active-regions' also accepts a new value, `only'.
+This means to only set the primary selection for temporarily active
+regions (usually made by mouse-dragging or shift-selection);
+"ordinary" active regions, such as those made with C-SPC followed by
+point motion, do not alter the primary selection.
-*** Yank commands, such as C-y and M-y, retrieve text from the
-clipboard if it is available.
+*** mouse-2 is now bound to `mouse-yank-primary'.
+This pastes from the primary selection, ignoring the kill-ring.
+Previously, mouse-2 was bound to `mouse-yank-at-click'.
-*** The above changes are reflected in the following new defaults:
+*** `x-select-enable-clipboard' now defaults to t on all platforms.
+*** `x-select-enable-primary' now defaults to nil.
+Thus, commands that kill text or copy it to the kill-ring (such as
+M-w, C-w, and C-k) also use the clipboard---not the primary selection.
-**** `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).
+**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
+exactly equivalent to, respectively M-w, C-w, and C-y.
-**** `mouse-2' is now bound to `mouse-yank-primary'.
-Previously, it was bound to `mouse-yank-at-click' (which is now
-unbound by default).
+**** Note that on MS-Windows, `x-select-enable-clipboard' was already
+non-nil by default, as Windows does not support the primary selection
+between applications.
-**** `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.
+*** To return to the previous behavior, do the following:
-**** `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.
-
-*** 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.
+**** Change `mouse-drag-copy-region' to t.
+**** Change `x-select-enable-primary' to t (on X only).
+**** Change `x-select-enable-clipboard' to nil.
+**** Bind `mouse-yank-at-click' to mouse-2.
*** Support for X cut buffers has been removed.
\f
* Changes in Specialized Modes and Packages in Emacs 24.1
+** The compile.el mode can be used without font-lock-mode.
+`compilation-parse-errors-function' is now obsolete.
+
+** 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.
*** An API for manipulating SQL product definitions has been added.
-** s-region.el is now declared obsolete, superceded by shift-select-mode
-enabled by default in 23.1.
+** sregex.el is now obsolete, since rx.el is a strict superset.
+** s-region.el and pc-select are now declared obsolete,
+superceded by shift-select-mode enabled by default in 23.1.
+** pc-mode.el is also declared obsolete.
** gdb-mi
*** GDB User Interface migrated to GDB Machine Interface and now
*** 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).
** 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.
+The vc-pull command 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.
+means to prompt the user for specifics, e.g. a pull location.
-**** vc-pull is an alias for vc-update.
+**** `vc-update' is now an alias for `vc-pull'.
-**** Currently supported by Bzr.
+**** Currently supported by Bzr, Git, and Mercurial.
*** 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.
+This merges another branch into the current one. This command prompts
+the user for specifics, e.g. a merge source.

-**** Currently supported by Bzr.
+** Miscellaneous
+
+---
+*** `copyright-fix-years' can optionally convert consecutive years to ranges.

* New Modes and Packages in Emacs 24.1
\f
* Incompatible Lisp Changes in Emacs 24.1
+** `copy-directory' now copies the source directory as a subdirectory
+of the target directory, if the latter is an existing directory. The
+new optional arg COPY-CONTENTS, if non-nil, makes the function copy
+the contents directly into a pre-existing target directory.
+
+** `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
\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
** Tool-bars can display separators.
Tool-bar separators are handled like menu separators in menu-bar maps,
-i.e. with entries of the form `(menu-item "--")'.
-
-Currently, tool-bar separators are only displayed on GTK.
+i.e. via menu entries of the form `(menu-item "--")'.
** Image API
*** 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.
