** The option `set-mark-default-inactive' has been deleted.
This unfinished feature was introduced by accident in Emacs 23.1;
simply disabling Transient Mark mode does the same thing.

** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
'inotify' API on GNU/Linux systems. On MS-Windows systems, this is
supported for Windows XP and newer versions.
+** Changes in autorevert.el
+
+---
+*** If Emacs is compiled with file notification support, notifications
+are used instead of checking the time stamp of the files. You can
+disable this by setting the user option `auto-revert-use-notify' to
+nil. Alternatively, a regular expression of directories to be
+excluded from file notifications can be specified by
+`auto-revert-notify-exclude-dir-regexp'.
+
+---
+*** The new user option `auto-revert-remote-files' enables reversion
+of remote files when set to non-nil.
+
** Face changes
*** The `face-spec-set' is now analogous to `setq' for face specs.
*** New face characteristic (supports :underline (:style wave))
specifies whether or not the terminal can display a wavy line.
+** Image API
+
++++
+*** `image-animated-p' is now `image-multi-frame-p'.
+It returns non-nil for any image that contains multiple frames,
+whether or not it specifies a frame delay.
+
++++
+*** When animating images that do not specify a frame delay,
+Emacs uses `image-default-frame-delay'.
+

+*** New functions `image-current-frame' and `image-show-frame' for getting
+and setting the current frame of a multi-frame image.
+
** time-to-seconds is not obsolete any more.
** New function special-form-p.
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
`preserve-extended-attributes' as it now handles both SELinux context
and ACL entries.

+has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer').
+The previous binding, introduced in Emacs 24.1, was a mistake, because
