supports local fonts (fonts installed on the machine where Emacs is
running). Additionally, the Xft library can be used for antialiasing
support, the otf library for complex text layout by OpenType fonts,
-and the m17n library for text shaping. Fontconfig-like font names
-(e.g. monospace-12) are accepted.
+and the m17n library for text shaping. Emacs now accepts font names
+supplied in the fontconfig format (e.g. "monospace-12:bold") and GTK
+format (e.g. "Monospace Bold 12").
** The new configuration option "--with-dbus" enables D-Bus language
bindings for Emacs.

* Changes in Emacs 23.1
+** `underline-minimum-offset' keeps the underline away from the baseline.
+
+** Info displays breadcrumbs in the header of the page.
+See Info-breadcrumbs-depth to control it.
+
+** Emacs now supports serial port access on GNU/Linux, Unix, and
+Windows. `serial-term' starts an interactive terminal,
+`make-serial-process' and `serial-process-configure' provide a Lisp
+interface. The serial port can be configured at runtime with the
+mode-line mouse menu.
+
+** Apropos
+*** `apropos-library' describes the elements defined in a given library.
+*** Set `apropos-compact-layout' is you want a more compact (but wider) layout.
+
** scroll-preserve-screen-position also preserves the column position.
** Completion.
*** `completion-styles' can be customized to choose your favorite completion.
** set-file-modes is now interactive and can take the mode value in
symbolic notation thanks to auxiliary functions.
-** split-window-preferred-function specifies whether display-buffer should
-split windows vertically or horizontally.
+** Changes affecting display-buffer
+*** New value nil for split-height-threshold inhibits vertical splitting
+unless there's no other window.
+*** New option split-width-threshold controls horizontal splitting.
+*** A window can be split horizontally even when it's not full-width.
+*** New option split-window-preferred-function can be set to a function
+to override the default splitting mechanism of display-buffer.
+
+** Menu Bar changes
+
+*** The Options menu contains a new entry to turn on Longlines mode.
+
+*** In the Options menu, the "Set Default Font" item applies the
+selected font to the `default' face on all frames, not just the
+current frame. This font setting will be saved if the "Save Options"
+item is used. Furthermore, if Emacs is compiled with both GTK and
+Fontconfig support, the "Set Default Font" item uses the GTK font
+selection dialog instead of an Emacs pop-up menu.
** Emacsclient has been extended to support opening a new terminal
frame. Its behavior has been changed to open a new Emacs frame by
*** The new function `face-all-attributes' returns an alist describing
all the basic attributes of a given face.
+*** S-down-mouse-1 now pops up a menu for changing the default font
+and text size of the default face in the current buffer. The face is
+changed via face remapping (see below).
+
*** FIXME face-remap
\f
* New Modes and Packages in Emacs 23.1
+** rst-mode for ReSTructured-Text files.
+
** FIXME add details of new packages imported from lisp/gnus.
[Maybe some information from doc/misc/gnus-coding.texi can be reused]
*** The VC mode-line entry now has a tooltip that explains the VC file status.
+*** In VC Annotate mode, for VC systems that support changesets, you can
+see the diff for the whole changeset (not only for the current file)
+by using the vc-annotate-show-changeset-diff-revision-at-line function.
+
*** In VC Annotate mode, you can type V to toggle the annotation visibility.
*** In VC Annotate mode, you can type f to show the file revision on
For now only CVS, RCS, SCCS and SVN support this functionality.
This is done by the `modify-change-comment' backend function.
+*** In log-view-mode, for VC systems that support changesets, you can
+see the diff for the whole changeset (not only for the current file)
+by typing the D key or using the "Changeset Diff" menu entry.
+
*** VC Support for Meta-CVS has been removed for lack of maintainer able
to update it to the new VC.
\f
* Changes in Emacs 23.1 on non-free operating systems
+** Case is now considered significant in completion on MS-Windows.
+The default value of `completion-ignore-case' is now nil on
+MS-Windows, the same as it is for other operating systems. The
+variable doesn't apply to reading a file name -- in that case Emacs
+heeds `read-file-name-completion-ignore-case' instead.
+
---
** IPv6 is supported on MS-Windows.
Emacs now supports IPv6 on Windows XP and later, and earlier versions
\f
* Lisp Changes in Emacs 23.1
+** The variable window-point-insertion-type determines the insertion-type
+of the marker used for window-point.
+
+** minibuffer-local-must-match-filename-map is now named
+minibuffer-local-filename-must-match-map.
+
** `all-completions' may now return the base size in the last cdr.
Since this means the returned list is not properly nil-terminated, this
is an incompatible change and is thus enabled by the new variable
** New function `match-substitute-replacement' returns the result of
`replace-match' without actually using it in the buffer.
+** The new variable `replace-search-function' determines the function
+to use for searching in query-replace and replace-string.
+
+** The new variable `replace-re-search-function' determines the
+function to use for searching in `query-replace-regexp',
+`replace-regexp', + `query-replace-regexp-eval', and
+`map-query-replace-regexp'.
+
** If a local hook function has a non-nil `permanent-local-hook'
property, then `kill-all-local-variables' does not remove it from
the local value of the hook variable. This means it remains
*** New function `font-get' returns a font property value.
+*** New function `font-face-attributes' returns a plist of face
+attributes set by a font.
+
*** New function `font-put' sets a font property value.
*** New function `list-fonts' returns a list of font-entities matching
\f
* New Packages for Lisp Programming in Emacs 23.1
+** The new major mode `special-mode' is intended as a parent for
+major modes such as those that set the "'mode-class 'special" property.
+
** find-cmd.el can build `find' commands using lisp syntax.
** The package isearch-multi.el has been added. It implements a new mode
