* 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.
\f
* Changes in Emacs 24.1
`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.
+
\f
* Editing Changes in Emacs 24.1
+++
** There is a new command `count-words-region', which does what you expect.
-** completion-at-point is now an alias for complete-symbol.
+** 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
*** 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.
** 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'.
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.
*** 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.
+
\f
* New Modes and Packages in Emacs 24.1
\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.
\f
* Lisp changes in Emacs 24.1
+** 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
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
*** 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.
