* Installation Changes in Emacs 24.4
-** Emacs can be compiled with POSIX ACL support.
+** Emacs can be compiled with ACL support.
This happens by default if a suitable support library is found at
build time, like libacl on GNU/Linux. To prevent this, use the
-configure option `--without-acl'.
+configure option `--disable-acl'.
+
+** The configure option --with-crt-dir has been removed.
+It is no longer needed, as the crt*.o files are no longer linked
+specially.
+
+** Emacs for MS-Windows can now be built by running the configure script
+using the MSYS environment and MinGW development tools.
+This is from now on the preferred method of building Emacs on
+MS-Windows. The Windows-specific configure.bat and makefile.w32-in
+files are deprecated. See the file nt/INSTALL.MSYS for detailed
+instructions.

using the scroll bar (i.e. dragging the thumb down even when the end
of the buffer is visible).
+** In compiled Lisp files, the header no longer includes a timestamp.
+

\f
* Editing Changes in Emacs 24.4
+** `split-window' is no longer a command, just a non-interactive function.
+As a command it was a special case of `split-window-below', and as such
+superfluous. After being reimplemented in Lisp, its interactive form
+was mistakenly retained.
+
** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
bound to <f11> and M-<f10>, respectively.
** In keymaps where SPC scrolls, S-SPC now scrolls in the reverse direction.
Eg View mode, etc.
+** New command `kmacro-to-register' to store keyboard macros in registers.
+
+** Shell Script mode
+
+*** `sh-mode' now has the mode own `add-log-current-defun-function'.
+You can pick the name of the function and the variables with `C-x 4 a'.
+
\f
* Changes in Specialized Modes and Packages in Emacs 24.4
+** `remember' 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.
+** `ido-decorations' has been slightly extended to give a bit more control.

+*** `desktop-auto-save-timeout' defines the number of seconds between
+auto-saves of the desktop.
+
** Dired
*** New minor mode `dired-hide-details-mode' hides details.
If set to a number, this can be used to avoid accidentally paste large
amounts of data into the ERC input.
+---
+** New F90 mode option `f90-smart-end-names'.

** Icomplete is a bit more like IDO.
*** key bindings to navigate through and select the completions.
*** The icomplete-separator is customizable, and its default has changed.
`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
next or previous frame. `F' (`image-goto-frame') shows a specific frame.
-*** `image-animated-p' is now `image-multi-frame-p'.

*** The command `image-mode-fit-frame' deletes other windows.
When toggling, it restores the frame's previous window configuration.
It also has an optional frame argument, which can be used by Lisp
callers to fit the image to a frame other than the selected frame.
+** Info

* 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
+using the same internal functions.
+
** New nadvice.el package offering lighter-weight advice facilities.
It is layered as:
- add-function/remove-function which can be used to add/remove code on any
\f
* Incompatible Lisp Changes in Emacs 24.4
+** Default process filers 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.
+Just as was the case in Emacs-22 and before, decoding of tty input according to
+keyboard-coding-system is not performed in read-event any more. But contrary
+to that past, it is still done before input-decode-map/function-key-map/...
+
** Removed inhibit-local-menu-bar-menus.
** frame-local variables that affect redisplay do not work any more.
\f
* Lisp Changes in Emacs 24.4
+** Obsoleted functions:
+*** `dont-compile'
+*** `lisp-complete-symbol'
+*** `field-complete'
+*** `minibuffer-completion-contents'
+
+** `with-wrapper-hook' is obsoleted by `add-function'.
+The few hooks that used with-wrapper-hook are replaced as follows:
+*** `abbrev-expand-function' obsoletes `abbrev-expand-functions'.
+*** `completion-in-region-function' obsoletes `completion-in-region-functions'.
+*** `filter-buffer-substring-function' obsoletes `filter-buffer-substring-functions'.
+
+
+** `get-upcase-table' is obsoleted by the new `case-table-get-table'.
+
** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files. This requires the
*** 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'
** The `defalias-fset-function' property lets you catch calls to defalias
and redirect them to your own function instead of `fset'.
+** The lock for 'DIR/FILE' is now 'DIR/.#FILE' and may be a regular file.
+When you edit DIR/FILE, Emacs normally creates a symbolic link
+DIR/.#FILE as a lock that warns other instances of Emacs that DIR/FILE
+is being edited. Formerly, if there was already a non-symlink file
+named DIR/.#FILE, Emacs fell back on the lock names DIR/.#FILE.0
+through DIR/.#FILE.9. These fallbacks have been removed, so that
+Emacs now no longer locks DIR/FILE in that case.
+
+On file systems that do not support symbolic links, the lock is now a
+regular file with contents being what would have been in the symlink.
+
** The 9th element returned by `file-attributes' is now unspecified.
Formerly, it was t if the file's gid would change if file were deleted
and recreated. This value has been inaccurate for years on many
`preserve-extended-attributes' as it now handles both SELinux context
and ACL entries.
+** Changes to the Emacs Lisp Coding Conventions in Emacs 24.4
+
+*** The package descriptor and name of global variables, constants,
+and functions should be separated by two hyphens if the symbol is not
+meant to be used by other packages.
+
\f
* Changes in Emacs 24.4 on Non-Free Operating Systems
Likewise, `file-name-buffer-file-type-alist' is now obsolete, and
modifying it has no effect.
+---
+** Lock files now work on MS-Windows.
+This allows to avoid losing your edits if the same file is being
+edited in another Emacs session or by another user. See the node
+"Interlocking" in the Emacs User Manual for the details. To disable
+file locking, customize `create-lockfiles' to nil.
+
** Improved fullscreen support on Mac OS X.
Both native (>= OSX 10.7) and "old style" fullscreen are supported.
Customize `ns-use-native-fullscreen' to change style. For >= 10.7
*** The constant `rst-version' describes the rst.el package version.
+** Ruby mode
+
+*** Support for percent literals and recognition of regular expressions
+in method calls without parentheses with more methods, including Cucumber
+steps definitions.
+
+*** Improved syntax highlighting and indentation.
+
+*** New command `ruby-toggle-block', bound to `C-c {'.
+
+*** Some non-standard keybindings/commands have been removed:
+
+**** `ruby-electric-brace'; use `electric-indent-mode' instead.
+
+**** `ruby-mark-defun'; use `mark-defun'.
+
+**** `ruby-beginning-of-defun' and `ruby-end-of-defun' are replaced by
+appropriate settings for the variables `beginning-of-defun-function'
+and `end-of-defun-function'.
+
+**** Non-standard keybindings for `backward-kill-word', `comment-region',
+`reindent-then-newline-and-indent' and `newline' have been removed.
+
** Shell Script mode
*** Pairing of parens/quotes uses `electric-pair-mode' instead of skeleton-pair.
*** The calendars produced by cal-html include holidays.
Customize `cal-html-holidays' to change this.
+** CEDET
+
+*** The major modes from the parser generators "Bovine" and "Wisent"
+are now properly integrated in Emacs. The file suffixes ".by" and ".wy"
+are in `auto-mode-alist', and the corresponding manuals are included.
+
+*** EDE
+
+**** Menu support for the "Configuration" feature. This allows users to
+choose the active configuration (such as debug or install) from the menu.
+
+**** New command `ede-set' to interactively set project-local variables.
+
+**** Support for compiling, debugging, and running in "generic" projects.
+
+**** Autoconf editing support for M4 macros with complex arguments.
+
+**** Compilation support for the "linux" project type.
+
+**** "simple" projects have been removed; use "generic" projects instead.
+
+*** Semantic
+
+**** Support for parsing #include statements inside a namespace in C/C++.
+
+**** Improved support for 'extern "C"' declarations in C/C++.
+
+**** The ability to ignore more common special C/C++ preprocessor symbols,
+such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++.
+If available, include cdefs.h as an additional source of preprocessor symbols.
+
+**** Improved C/C++ function pointer parsing.
+
+**** In Python, support for converting imports to include file names.
+
+**** Ability to dynamically determine the Python load path.
+
+**** Support for the Python 'WITH' and 'AT' keywords.
+
+**** Improved tooltip completion.
+
+*** SRecode
+
+**** The SRecode manual is now included.
+
+**** Tag generation supports constructor/destructor settings and system
+include differentiation.
+
+**** Addition of 'Framework' support: Frameworks are specified when a
+particular kind of library (such as Android) is needed in a common language
+mode (like Java).
+
+**** Support for nested templates and let variables override based on priority.
+
+**** Support for merging tables from multiple related modes, such as
+default -> c++ -> arduino.
+
** Compile has a new option `compilation-always-kill'.
** Customize
*** Last-modified time stamps in undo lists now are of the form
(t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS).
+** EIEIO
+
+*** Improved security when handling persistent objects:
+
+**** `eieio-persistent-read' now features optional arguments for specifying
+the class to load, as well as a flag stating whether subclasses are allowed;
+if provided, other classes will be rejected by the reader. For
+compatibility with existing code, if the class is omitted only a
+warning is issued.
+
+**** New specialized reader for pulling in classes and signaling errors
+without evaluation of suspicious code.
+
+**** All slots that contain objects must have a :type. Slots with lists
+of objects must use a new type predicate for a list of an object type.
+
+*** Support for `find-function' and similar utilities, through the addition
+of filename support to generated symbols.
+
** Floating point functions now always return special values like NaN,
instead of signaling errors, if given invalid args; e.g., (log -1.0).
Previously, they returned NaNs on some platforms but signaled errors
