configure option `--disable-acl'.
+** Emacs can be compiled with file notification support.
+The configure option `--with-file-notification=LIB' enables file
+notification support in Emacs. This option's value should be `yes',
+`no', `gfile', `inotify' or `w32'. `yes' is a synonym for `w32' on
+MS-Windows, and for `gfile' otherwise. The default value is `yes'.

** The configure option --with-crt-dir has been removed.
It is no longer needed, as the crt*.o files are no longer linked

* Startup Changes in Emacs 24.4
** `initial-buffer-choice' can now specify a function to set up the
initial buffer.
+** `remember-notes' creates a buffer whose content is saved on kill-emacs.
+You may 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, *scratch* buffer will still be there for notes that do not
+need to be preserved.
+
** `write-region-inhibit-fsync' now defaults to t in batch mode.
** ACL support has been added.
using the scroll bar (i.e. dragging the thumb down even when the end
of the buffer is visible).
+** New function `add-face-text-property' has been added, which can be
+used to conveniently prepend/append new face attributes to text.
+
** In compiled Lisp files, the header no longer includes a timestamp.
** Multi-monitor support has been added.
`frame-monitor-attributes' can be used to obtain information about
each physical monitor on multi-monitor setups.
+*** The functions `display-pixel-width' and `display-pixel-height' now
+behave consistently among the platforms: they return the pixel width
+or height for all physical monitors associated with the given display
+as just they were on X11. To get information for each physical
+monitor, use the new functions above. Similar notes also apply to
+`x-display-pixel-width', `x-display-pixel-height', `display-mm-width',
+`display-mm-height', `x-display-mm-width', and `x-display-mm-height'.

* Editing Changes in Emacs 24.4
** In keymaps where SPC scrolls, S-SPC now scrolls in the reverse direction.
Eg View mode, etc.
++++
+** New option `visual-order-cursor-movement'.
+If this is non-nil, cursor motion with arrow keys will follow the
+visual order of characters on the screen: <left> always moves to the
+left, <right> always moves to the right, disregarding the surrounding
+bidirectional context.
+
** New command `kmacro-to-register' to store keyboard macros in registers.
** Shell Script mode
pager by default. See `eshell-visual-subcommands' and
`eshell-visual-options'.
+** If your Emacs is compiled with libxml2 support, you can use the new
+built-in web browser `eww'.
+
** `remember' can now store notes in separates files
You can use the new function `remember-store-in-files' within the
`remember-handler-functions' option.
** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.

++++
+*** By default, prefix arguments do not now terminate Isearch mode.
+Set `isearch-allow-prefix' to nil to restore old behavior.
+
+*** More Isearch commands accept prefix arguments, namely
+`isearch-printing-char', `isearch-quote-char', `isearch-yank-word',
+`isearch-yank-line'.
+
+*** Word search now matches whitespace at the beginning/end
+of the search string if it contains leading/trailing whitespace.
+In an incremental word search or when using a non-nil LAX argument
+of `word-search-regexp', the lax matching can also match part of
+the first word (in addition to the lax matching of the last word).
+The same rules are now applied to the symbol search with the difference
+that it matches symbols, and non-symbol characters between symbols.

** MH-E has been updated to MH-E version 8.5.
See MH-E-NEWS for details.
When its arg ADJACENT is non-nil (when called interactively with C-u C-u)
it works like the utility `uniq'. Otherwise by default it deletes
duplicate lines everywhere in the region without regard to adjacency.

-duplicate blank lines are preserved.
+When its arg KEEP-BLANKS is non-nil (when called interactively with
+C-u C-u C-u), duplicate blank lines are preserved.
** New `cycle-spacing' command allows cycling between having just one
space, no spaces, or reverting to the original spacing. Like
`just-one-space' command it can handle or ignore newlines and
leave different number of spaces.
+** Todo mode has been rewritten and enhanced.
+New features include:
+- support for multiple todo files and archive files of done items;
+- renaming, reordering, moving, merging, and deleting categories;
+- sortable tabular summaries of categories and the types of items they contain;
+- cross-category lists of items filtered by specific criteria;
+- more fine-grained interaction with the Emacs diary, by being able to decide
+ for each todo item whether it appears in the Fancy Diary display;
+- highly flexible new item insertion and item editing;
+- moving items between categories, storing done items in their category or in
+ archive files, undoing or unarchiving done items;
+- reprioritizing items by inputting a numerical priority;
+- extensive customizability of operation and display, including numerous faces.
+To support some of these features, a new file format is used, which is
+incompatible with the old format; however, you can convert old todo and done
+item files to the new format on initializing the first new todo file, or at any
+later time with the provided conversion command. The old version of
+todo-mode.el has been made obsolete and renamed otodo-mode.el.

* New Modes and Packages in Emacs 24.4
+
** New `superword-mode' in subword.el
`superword-mode' overrides the default word motion commands to treat
symbol_words as a single word, similar to what `subword-mode' does and
- advice-add/advice-remove to add/remove a piece of advice on a named function,
much like `defadvice' does.
+** The package file-notify.el provides an interface for file system
+notifications. It requires, that Emacs is compiled with one of the
+low-level libraries gfilenotify.c, inotify.c or w32notify.c.
+
\f
* Incompatible Lisp Changes in Emacs 24.4
-** Default process filers and sentinels are not nil any more.
+** The syntax of ?» and ?« is now punctuation instead of matched parens.
+Some languages match those as »...« and others as «...» so better stay neutral.
+
+** The default file coding for Emacs Lisp files is now utf-8.
+(See file-coding-system-alist.) In most cases, this change is transparent, but
+files that contain unusual characters without specifying an explicit coding
+system may fail to load with obscure errors.
+You should either convert them to utf-8 or add an explicit `coding:' cookie.
+
+** overriding-terminal-local-map does not replace the local keymaps any more.
+It used to disable the minor mode, major mode, and text-property keymaps,
+whereas now it simply has higher precedence.
+
+** Default process filters and sentinels are not nil any more.
Instead they default to a function which does what the nil value used to do.
** `read-event' does not return decoded chars in ttys any more.
\f
* Lisp Changes in Emacs 24.4
++++
+** New macro with-eval-after-load. Like eval-after-load, but better behaved.

** Obsoleted functions:
+*** `log10'
*** `dont-compile'
*** `lisp-complete-symbol'
*** `field-complete'
*** `minibuffer-completion-contents'
*** `isearch-nonincremental-exit-minibuffer'
*** `isearch-filter-visible'
+*** `generic-make-keywords-list'
** `with-wrapper-hook' is obsoleted by `add-function'.
The few hooks that used with-wrapper-hook are replaced as follows:
** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files. This requires the
-'inotify' API on GNU/Linux systems. On MS-Windows systems, this is
-supported for Windows XP and newer versions.

** Changes in autorevert.el
** Face changes
-*** The `face-spec-set' is now analogous to `setq' for face specs.
+*** The function `face-spec-set' is now analogous to `setq' for face specs.
Its third arg now accepts values specifying exactly which face spec to
set (defface, custom, or user spec), and it directly sets the relevant
property using the supplied face spec.
`imagemagick-filter-types' returns the list of types that will be
treated as images.
+*** ImageMagick images now support the :max-width and :max-height
+keywords.

** Minibuffer
*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
The `url-retrieve' function now uses this to encode its URL argument,
in case that is not properly encoded.
+*** New command `url-cookie-list' displays all the current cookies, and

** notifications.el supports now version 1.2 of the Notifications API.
The function `notifications-get-capabilities' returns the supported
server properties.
modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
on-the-fly spell checking for comments and strings.
+**** New minor modes `prettify-symbols-mode' and
+`global-prettify-symbols-mode' let the user enable symbol
+prettification (replacing a string like "lambda" with the Greek lambda
+character).
+
*** New hook `change-major-mode-after-body-hook', run by
`run-mode-hooks' just before any other mode hooks.
