* 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'.
+
+** 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 specially.
+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 Posix configure script and Makefile's also means a change in
+the directory structure of the Emacs installation on Windows. It is
+now the same as on GNU and Unix systems. In particular, the auxiliary
+programs, such as cmdproxy.exe and hexl.exe, are in
+libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs
+version), version-independent site-lisp is in share/emacs/site-lisp,
+version-specific Lisp files are in share/emacs/VERSION/lisp and in
+share/emacs/VERSION/site-lisp, Info docs are in share/info, and data
+files are in share/emacs/VERSION/etc. (Emacs knows about all these
+directories and will find the files in there automatically; there's no
+need to set any variables due to this change.)
+
+** Directories passed to configure option `--enable-locallisppath' are
+no longer created during installation.

** `apropos-variable' is now `apropos-user-option'
`apropos-user-option' shows all user options while `apropos-variable'
** `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.
+++
*** Emacs preserves the ACL entries of files when backing up.
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.
+
+*** New functions `display-monitor-attributes-list' and
+`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'.
+
\f
* 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
\f
* Changes in Specialized Modes and Packages in Emacs 24.4
+** `eshell' now supports visual subcommands and options
+Eshell has been able to handle "visual" commands (interactive,
+non-line oriented commands such as top that require display
+capabilities not provided by eshell) by running them in an Emacs
+terminal emulator. See `eshell-visual-commands'.
+
+This feature has been extended to subcommands and options that make a
+usually line-oriented command a visual command. Typical examples are
+"git log" and "git <command> --help" which display their output in a
+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.
+
+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.
** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.
Affected files:
~/.emacs.d/timelog replaces ~/.timelog
-~/.emacs.d/todo-do replaces ~/.todo-do
-~/.emacs.d/todo-done replaces ~/.todo-done

** cl-lib
*** New macro cl-tagbody.
*** Support for ISO 8601 dates.
+** Desktop
+
+*** `desktop-auto-save-timeout' defines the number of seconds between
+auto-saves of the desktop.
+
+*** `desktop-restore-frames enables saving and restoring the window/frame
+configuration.
+
** 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.
-** Icomplete is a bit more like IDO.
+---
+** New F90 mode option `f90-smart-end-names'.

entries displayed by `Info-index-next', `Info-virtual-index' and
`info-apropos'.
-** Isearch
+** Hi-Lock
+
+*** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands
+will cycle through faces in `hi-lock-face-defaults' without prompting.
+
++++
+*** New global command `M-s h .' (`highlight-symbol-at-point')
+highlights the symbol found near point without prompting,
+using the next face automatically.
+
+** Search and Replace
+
+*** New global command `M-s .' (`isearch-forward-symbol-at-point')
+starts a symbol (identifier) incremental search forward with the
+symbol found near point added to the search string initially.
*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
and adds it to the search string.
+*** `M-s i' in Isearch mode toggles the variable `isearch-invisible'
+between nil and the value of the option `search-invisible' (or `open'
+when it's nil).
+
+*** `query-replace' skips invisible text when `search-invisible' is nil,
+and opens overlays with hidden text when `search-invisible' is `open'.
+
++++
+*** 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.

name and arguments. Useful to trace the value of (current-buffer) or
(point) when the function is invoked.
-** New command `delete-duplicate-lines' has two types of operation:
-when its arg ADJACENT is non-nil (when called interactively with C-u C-u)
+** New command `delete-duplicate-lines' has new types of operation:
+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.
+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
+** 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.
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

+*** `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
-'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.
`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.

** 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

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).
