configure option `--disable-acl'.

generated class. For generic functions, it will show all
*** 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 windows customize the frame parameter
-right-divider-width to some positive integer. To put dividers between
-vertically stacked windows set the frame parameter bottom-divider-width
-to some positive integer. Dividers can be dragged with the mouse and
-show a corresponding cursor when the mouse hovers over them. The
-appearance of dividers can be changed by customizing the basic faces
-window-divider, window-divider-first-pixel and window-divider-last-pixel
-where the latter two are useful to provide a 3D effect or to better set
-dividers apart from surrounding display objects.

`(eval-expression-)print-level' to nil. Additionally, it causes integers
to be printed in other formats (octal, hexadecimal, and character).

`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.
---
** 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.
+---
** The default value of `comment-use-global-state' is now t,
and this variable has been marked obsolete.
** `emacs-bzr-version' has been renamed to `emacs-repository-version',
and works for git too, if you fetch the repository notes.

** Battery information can now be retrieved from BSD's `apm' utility.
** CUA mode
++++
*** CUA mode now uses `delete-selection-mode' and `shift-select-mode'.
Hence, you can now enable it independently from those modes, and from
`transient-mark-mode'.
*** `cua-highlight-region-shift-only' is now obsolete.
You can disable `transient-mark-mode' to get the same result.

+`cua-rectangle-mark-mode'.
** CFEngine mode
** Desktop
-*** `desktop-auto-save-timeout' defines the number of seconds idle time
-before auto-save of the desktop.

In `electric-pair-mode', inserting a newline between adjacent pairs
opens an extra newline after point, which is indented if
`electric-indent-mode' is also set.
++++
*** New option `electric-pair-skip-whitespace', enabled by default.
This controls if skipping over closing delimiters should jump over any
whitespace slack. Setting it to `chomp' makes it delete this
whitespace. See also the variable `electric-pair-skip-whitespace-chars'.
+---
*** New variables control the pairing in strings and comments.
You can customize `electric-pair-text-pairs' and
`electric-pair-text-syntax-table' to tweak pairing behavior inside
strings and comments.

*** The format of `archive-contents' files, generated by package
repositories, has changed to allow a new (fifth) element in the data
vectors, containing an associative list with extra properties.

+display a "Homepage" header.)
---
** In Prolog mode, `prolog-use-smie' has been removed,
** Remember
-*** The new command `remember-notes' creates a buffer that is saved on
-`kill-emacs'. You can think of it as a *scratch* buffer whose content
-is preserved. In fact, it was designed as a replacement for *scratch*
-buffer and can be used that way by setting `initial-buffer-choice' to
-`remember-notes' and `remember-notes-buffer-name' to "*scratch*".
-Without the second change, the *scratch* buffer will still be there
-for notes that do not need to be preserved.
++++
+*** The new command `remember-notes' creates a buffer that is saved on exit.
+You can use it as a more permanent *scratch* buffer.
-*** The Remember package can now store notes in separates files.
-You can use the new function `remember-store-in-files' within the
-`remember-handler-functions' option. See `remember-data-directory'
-and `remember-directory-file-name-format' for new options related to
-this function.
++++
+*** Remember can now store notes in separate files.
+To use this, add `remember-store-in-files' to the `remember-handler-functions'
+option. The files are saved in `remember-data-directory' using
+names specified by `remember-directory-file-name-format'.
** Rmail
Emacs can learn the appropriate indentation settings if you provide it
with an indented sample file.
+---
+** SQL
+Improved login monitoring and appropriate response to login failures.
+Includes `sql-login-delay' to define maximum wait for a connection.
+
+*** Oracle support
+SQL*Plus script placeholders are properly highlighted and identified
+in `sql-placeholders-filter' correctly. When SQL*Plus is started,
+options specified in `sql-oracle-options' are passed before the logon
+parameter, as SQL*Plus expects. The default setting for
+`sql-oracle-options' has been altered to pass the `-L' option to limit
+the number of logon attempts per invocation.

* New Modes and Packages in Emacs 24.4
** New package `eww' is a built-in web browser.
It is only available if Emacs is compiled with libxml2 support.
++++
** New minor mode `superword-mode'.
This overrides the default word motion commands to treat "symbol_words"
as a single word, similar to what `subword-mode' does.
Generic commands are interactive functions whose implementation can be
selected among several alternatives, as a matter of user preference.
-** The `defalias-fset-function' property lets you catch `defalias'
-calls, and redirect them to your own function, instead of `fset'.
++++
+** If you give a symbol a `defalias-fset-function' property, `defalias'
+on that symbol will use the associated value as a function to call
+in place of `fset'.
+++
** New variable `enable-dir-local-variables'.
+++
** New function `get-pos-property'.
++++
+** `read-regexp' now uses the new variable `read-regexp-defaults-function'
+as a function to call to provide default values.
+
** Completion changes
*** The separator for `completing-read-multiple' can now be a regexp.
see the `apropos' Custom group for details.
*** The old options whose values specified faces to use have been removed
-(i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.).
+(i.e. `apropos-symbol-face', `apropos-keybinding-face', `apropos-label-face',
+`apropos-match-face' and `apropos-property-face'.).
