* Installation Changes in Emacs 25.1
+++
+
** Building Emacs now requires C99 or later.
+** The default value of `history-length' has increased to 100.
+
+** The variable `redisplay-dont-pause' is obsolete.
+
** Building Emacs now requires GNU make, version 3.81 or later.
+** `call-process-shell-command' and `process-file-shell-command' no longer
+take "&rest args".
+
+** The option `browse-url-firefox-startup-arguments' no longer has an effect.
+
** By default, Emacs no longer works on IRIX. We expect that Emacs
users are not affected by this, as SGI stopped supporting IRIX in
December 2013. If you are affected, please send a bug report. You
undumping code to GCC under IRIX, or by configuring --with-wide-int,
or by sticking with Emacs 24.4.
+** ERC
+
** 'configure' now prefers gnustep-config when configuring GNUstep.
If gnustep-config is not available, the old heuristics are used.
++++
+*** New option `erc-rename-buffers'.
+
+*** New faces `erc-my-nick-prefix-face' and `erc-nick-prefix-face'.
+
+*** `erc-format-@nick' displays all user modes instead of only op and voice.
+
+*** The display of irc commands in the current buffer has been disabled.
+
+*** `erc-version' now follows the Emacs version.
+
+** Obsolete packages
+
+*** cc-compat.el
+
---
** The configure option `--with-pkg-config-prog' has been removed.
Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.
+*** crisp.el (moved to elpa.gnu.org)
+
** The configure option '--enable-silent-rules' is now the default,
and silent rules are now quieter. To get the old behavior where
'make' chatters a lot, configure with '--disable-silent-rules' or
build with 'make V=1'.
+*** tpu-edt.el, ws-mode.el
+These emulations of old editors are believed to be no longer relevant
+ - contact emacs-devel@gnu.org if you disagree.
+
---
** The configure option '--with-gameuser' now allows to specify a
group instead of a user if its argument is prefixed by ':' (a colon).
It has no particular connection to Emacs and has not changed in years,
so if you want to use it, you can always take a copy from an older Emacs.
+*** vi.el, vip.el (try M-x viper instead)
+
\f
* Startup Changes in Emacs 25.1
*** The <class> variables are declared obsolete.
*** The <initarg> variables are declared obsolete.
*** defgeneric and defmethod are declared obsolete.
+*** `constructor' is now an obsolete alias for `make-instance'.
** ido
*** New command `ido-bury-buffer-at-head' bound to C-S-b
** eww
+---
+*** HTML can now be rendered using variable-width fonts.
+
++++
+*** A new command `F' (`eww-toggle-fonts') can be used to toggle
+whether to use variable-pitch fonts or not. The user can also
+customize the `shr-use-fonts' variable.
+
+++
*** A new command `R' (`eww-readable') will try do identify the main
textual parts of a web page and display only that, leaving menus and
*** Two new faces `compare-windows-removed' and `compare-windows-added'
replace the obsolete face `compare-windows'.
+** VHDL mode supports VHDL'08.
+
** Calculator: decimal display mode uses "," groups, so it's more
fitting for use in money calculations; factorial works with
non-integer inputs.
** tar-mode: new `tar-new-entry' command, allowing for new members to
be added to the archive.
+** Autorevert: dired buffers are also auto-reverted via file
+notifications, if Emacs is compiled with file notification support.
+
** Obsolete packages

denied" instead of "permission denied". The old behavior was problematic
in languages like German where downcasing rules depend on grammar.
++++
+** The character classes [:alpha:] and [:alnum:] in regular expressions
+now match multibyte characters using Unicode character properties.
+If you want the old behavior where they matched any character with
+word syntax, use `\sw' instead.
+
\f
* Lisp Changes in Emacs 25.1
+** Emacs Lisp now supports generators.
+
+** New finalizer facility for running code when objects
+ become unreachable.
+
** lexical closures can use (:documentation <form>) to build their docstring.
It should be placed right where the docstring would be, and <form> is then
evaluated (and should return a string) when the closure is built.
or Windows Server 2003. The built binaries still run on all versions
of Windows starting with Windows 9X.
++++
+** Emacs running on MS-Windows now supports the daemon mode.
+
** OS X 10.5 or older is no longer supported.
** OS X on PowerPC is no longer supported.
