** Emacs can now be compiled with file notification support.
This happens by default if a suitable system library is found at
build time. To prevent this, use the configure option
-`--with-file-notification-no'. See below for file-notify features.
+`--without-file-notification'. See below for file-notify features.
FIXME? This feature is not available for the Nextstep port. (?)

If you want the previous behavior, whereby F10 invoked `tmm-menubar',
customize the option `tty-menu-open-use-tmm' to a non-nil value.
-(Typing M-` will always invoke `tmm-menubar', even if
-`tty-menu-open-use-tmm' is nil.)

** The *Messages* buffer is created in `messages-buffer-mode',
*** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
bound to <f11> and M-<f10>, respectively.
-*** New command `frameset-to-register' is now bound to `C-x r f', replacing
-`frame-configuration-to-register'. It offers similar functionality,
-plus enhancements like the ability to restore deleted frames. The
-command `frame-configuration-to-register' still exists, but is unbound.

*** New hooks `focus-in-hook', `focus-out-hook'.
These are normal hooks run when an Emacs frame gains or loses input focus.

+*** Emacs can now draw dividers between adjacent windows.
+To put dividers between side-by-side/vertically stacked windows
+customize the frame parameter `right-divider-width'/`bottom-divider-width'
+to some positive integer. You can drag dividers with the mouse
+(they show a corresponding cursor when the mouse hovers over them).
+You can change the appearance of dividers by customizing the faces
+`window-divider', `window-divider-first-pixel', and
+`window-divider-last-pixel'. The last two are useful to provide a 3D
+effect, or to better distinguish dividers from surrounding display objects.

*** `split-window' is now a non-interactive function, not a command.
As a command, it was a special case of `C-x 2' (`split-window-below'),

`eval-expression' on entering the minibuffer.
** `write-region-inhibit-fsync' now defaults to t in batch mode.

-** `cache-long-line-scans' has been renamed to `cache-long-scans'
+** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans',
because it affects caching of paragraph scanning results as well.
-Also, it is now enabled by default.
+There is no reason to set this to nil except for debugging purposes.

** `emacs-bzr-version' has been renamed to `emacs-repository-version',
and works for git too, if you fetch the repository notes.
-** `read-regexp-defaults-function' defines a function to provide default
-values for reading regexps by commands like `rgrep', `lgrep' `occur',
-`highlight-regexp', etc. You can customize this to specify a function
-that provides a default value from the regexp last history element,
-or from the symbol found at point.

** New option `load-prefer-newer' affects how the `load' function chooses
the file to load. If this is non-nil, then when both .el and .elc
Interactive commands that read registers and want to make use of this
should use `register-read-with-preview' to read register names.
+*** New command `frameset-to-register' bound to `C-x r f', replacing

+plus enhancements like the ability to restore deleted frames.

** New EPA option `epa-mail-aliases'.
-You can set this to a list of alias expansions for keys to use
-in `epa-mail-encrypt'.
-
-If one element of the variable's value is ("foo@bar.com" "foo@hello.org"),
-that means: when one of the recipients of the message being encrypted
-is `foo@bar.com', encrypt the message for `foo@hello.org' instead.
-
-If one element of the variable's value is ("foo@bar.com"),
-that means: when one of the recipients of the message being encrypted
-is `foo@bar.com', ignore that name as regards encryption.
-This is useful to avoid a query when you have no key for that name.
+You can set this to a list of email address aliases that `epa-mail-encrypt'
+should use to find keys.
