Log Message:
Update to 24.4.
DragonFly and giflib-5.x patches are included upstream.
libutil linking doesn't seem to be needed, remove it as well.
I can build emacs on -current without any patches, let me know if you
see breakage.

* Installation Changes in Emacs 24.4

** Emacs can now be compiled with ACL (access control list) 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 `--disable-acl'.  See below for the features this provides.

** 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
`--without-file-notification'.  See below for file-notify features.
This feature is not available for the Nextstep port.

** Emacs can now be compiled with zlib support.
This happens by default if zlib is present, which it normally is.
To prevent this, use the configure option `--without-zlib'.
This provides the function `zlib-decompress-region'; see below for details.

** The configure option `--without-compress-info' has been generalized,
and renamed to `--without-compress-install'.  It now prevents compression
of _any_ files during installation.

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

** Directories passed to configure option `--enable-locallisppath' are
no longer created during installation.

** Emacs for Nextstep (Mac OS X, GNUstep) can be built with ImageMagick support.
This requires pkg-config to be available at build time.

* Startup Changes in Emacs 24.4

** When initializing `load-path', an empty element in the EMACSLOADPATH
environment variable (either leading, e.g., ":/foo"; trailing, e.g.,
"/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default
load-path (the one that would have been used if EMACSLOADPATH was unset).
This makes it easier to _extend_ the load-path via EMACSLOADPATH
(previously, EMACSLOADPATH had to specify the complete load-path,
including the defaults).  (In older versions of Emacs, an empty element
was replaced by ".", so use an explicit "." now if that is what you want.)

** The -L option, which normally prepends its argument to load-path,
will instead append, if the argument begins with `:' (or `;' on MS Windows;
i.e., `path-separator').

** If you use either site-load.el or site-init.el to customize the dumped
Emacs executable, any changes to `load-path' that these files make
will no longer be present after dumping.  To affect a permanent change
to `load-path', use the `--enable-locallisppath' option of `configure'.

** The user option `initial-buffer-choice' can now specify a function
to set up the initial buffer.

* Changes in Emacs 24.4

** Support for ACLs (access control lists).
This requires a suitable support library to be found at build time.
On GNU/Linux, the POSIX ACL interface is used via libacl.
On MS-Windows, the NT Security APIs are used to emulate the POSIX interface.
ACLs are extended file attributes, used e.g. for finer-grained permissions.

*** Emacs preserves the ACL entries of files when backing up.

*** New functions `file-acl' and `set-file-acl' get and set file ACLs.

** Support for menus on text-mode terminals.
If the terminal supports a mouse, clicking on the menu bar, or on
sensitive portions of the mode line or header line, will drop down the
menu defined at that position.  Likewise, clicking C-mouse-1, C-mouse-2, or
C-mouse-3 on the text area will pop up the menus defined for those locations.

If the text terminal does not support a mouse, you can activate the
first menu-bar menu by typing F10, which invokes `menu-bar-open'.

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

** 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
versions of a file exist, and the caller did not explicitly specify
which one to load, then the newer file is loaded.  The default, nil,
means to always load the .elc file.

** Multi-monitor support

*** 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 if they were on X.  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'.

** New function `zlib-decompress-region', which decompresses gzip- and
zlib-format compressed data using built-in zlib support (if available).

** The *Messages* buffer is created in `messages-buffer-mode',
a new major mode, with read-only status.  Any code that might create
the *Messages* buffer should call the function `messages-buffer' to do
so and set up the mode.

** The cursor stops blinking after 10 blinks (by default) on X and Nextstep.
You can change the default by customizing `blink-cursor-blinks'.

** In keymaps where SPC scrolls forward, S-SPC now scrolls backward.
This affects View mode, etc.

** The default value of `make-backup-file-name-function' is no longer nil.
Instead it defaults to a function that does what the nil value used to.

** Help

*** The command `apropos-variable' is renamed to `apropos-user-option'.
`apropos-user-option' shows all user options, while `apropos-variable'
shows all variables.  When called with a universal prefix argument,
the two commands swap their behaviors.  When `apropos-do-all' is
non-nil, they output the same results.

*** The key `?' now describes prefix bindings, like `C-h'.

*** The command `describe-function' has been extended for EIEIO.
Running it on constructors will show a full description of the
generated class.  For generic functions, it will show all
implementations together with links to the source.  The old commands
`describe-class', `describe-constructor' and `describe-generic' were
removed.

*** The function `quail-help' is no longer an interactive command.
Use `C-h C-\' (`describe-input-method') instead.

** Frame and window handling

*** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
bound to <f11> and M-<f10>, respectively.

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

*** The function `window-in-direction' now takes additional arguments
for specifying a reference point, wrapping the selection around frame
borders, and specifying ways to select the minibuffer window.

*** Emacs can now change frame sizes in units of pixels, rather than
text rows or columns.  When maximizing a frame or making it fullscreen,
remaining extra pixels are no longer given to the minibuffer, the rightmost
fringe, or other unusable space, but are distributed among the text
areas of the frame's windows.  If the new option `frame-resize-pixelwise'
is non-nil, all frame size changes happen pixelwise and set the
corresponding size hints for the window manager.

*** Emacs can now change window sizes in units of pixels.
Mouse-dragging a mode line or window divider now changes the size of
adjacent windows pixelwise.  If the new option `window-resize-pixelwise'
is non-nil, functions like `balance-windows-area' and `fit-window-to-buffer'
resize windows pixelwise.  Most functions for changing or accessing
window sizes now have an additional argument that allows changes to apply,
or values to be returned, in pixels instead of lines/columns.

*** The functions `window-body-height' and `window-body-width' now never
count partially visible lines or columns if called with a nil PIXELWISE
argument.

*** Emacs can now draw dividers between adjacent windows.  To put
dividers between side-by-side/vertically stacked windows customize the
frame parameters `right-divider-width' and `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.

*** New functions to return the pixel sizes of window components, namely
`window-scroll-bar-width', `window-mode-line-height',
`window-header-line-height', `window-right-divider-width', and
`window-bottom-divider-width'.

*** The new function `window-text-pixel-size' returns the size of the
text of a window's buffer in pixels.  This allows functions like
`fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a
window to its buffer as it will be displayed.

*** `fit-window-to-buffer' can now resize windows in both dimensions.
This behavior is controlled by the new option
`fit-window-to-buffer-horizontally'.  The new option
`fit-frame-to-buffer' allows you to fit the window's frame to its buffer.

*** `fit-frame-to-buffer' now fits frames in both dimensions.  The new
options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes'
control the size of the frame and its position on screen.

*** Temp Buffer Resize Mode can now adjust the height and width of
windows and frames.  The new option `temp-buffer-max-width' allows you to
control the width of temporary buffer windows.  Moreover, if the new
option `fit-frame-to-buffer' is non-nil and the buffer appears in the
root window of a frame, Temp Buffer Resize Mode will try to adjust the
width and/or height of the frame.

*** `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'),
and as such superfluous.  After being reimplemented in Lisp, its
interactive form was mistakenly retained.

*** The functions `window-size' and `window-total-size' now have an
optional argument to return a rounded size value.

*** `window-state-put' now allows you to put a window state into internal
windows too.

*** New option `scroll-bar-adjust-thumb-portion'.
Available only on X, this option allows you to control over-scrolling
using the scroll bar (i.e., dragging the thumb down even when the end
of the buffer is visible).

*** New display actions functions for `display-buffer':

**** `display-buffer-at-bottom' chooses or creates a window at the
bottom of the selected frame.

**** `display-buffer-no-window' to not display the buffer in a window.

*** New display action alist entry `allow-no-window' to indicate the
caller of `display-buffer' is ready to handle the case of not displaying
the buffer in a window.

*** `display-buffer-in-previous-window' is now a member of
`display-buffer-fallback-action'.

** Lisp evaluation

*** `eval-defun' on an already defined defcustom calls the :set function,
if there is one.

*** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'),
and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a
zero prefix argument.  This disables truncation of lists in the output,
equivalent to setting `(eval-expression-)print-length' and
`(eval-expression-)print-level' to nil.  Additionally, it causes integers
to be printed in other formats (octal, hexadecimal, and character).

*** New hook `eval-expression-minibuffer-setup-hook' run by
`eval-expression' on entering the minibuffer.

** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans',
because it affects caching of paragraph scanning results as well.
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.

** The default value of `comment-use-global-state' is now t,
and this variable has been marked obsolete.

** `write-region-inhibit-fsync' now defaults to t in batch mode.

** 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.

* Editing Changes in Emacs 24.4

** Indentation

*** `electric-indent-mode' is now enabled by default.
Typing RET reindents the current line and indents the new line.
`C-j' inserts a newline but does not indent.  In some programming modes,
additional characters are electric (eg `{').

*** New buffer-local `electric-indent-local-mode'.

*** The behavior of `C-x TAB' (`indent-rigidly') has changed.
When invoked without a prefix argument, it now activates a transient
mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts
the text indentation in the region.  Typing any other key resumes
normal editing behavior.

*** `tab-stop-list' is now implicitly extended to infinity by repeating
the last step.  Its default value is changed to nil, which means a tab
stop every `tab-width' columns.

** Uniquify is enabled by default, with `post-forward-angle-brackets' style.
In other words, if you visit two files that have the same base name,
then rather than creating buffers basename and basename<2>,
Emacs uses basename<dirA> and basename<dirB>.  To change this,
customize `uniquify-buffer-name-style'.  Set it to nil for the old behavior.

** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region.
Most commands are still unaware of it, but kill/yank do work on the rectangle.

** 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 `delete-duplicate-lines'.
This searches the region for identical lines, and removes all but one
copy of each repeated line.  The lines need not be sorted.

** New command `cycle-spacing' acts like a smarter `just-one-space'.
When called in succession, it cycles between spacing conventions:
one space, no spaces, original spacing.

** `blink-matching-paren' now only highlights the matching open-paren
by default, instead of moving the cursor.  Set this variable to `jump' to
restore the old behavior.

** The new function `fill-single-char-nobreak-p' can stop fill from breaking
a line after a one-letter word, which is an error in some typographical
conventions.  To use it, add it to the `fill-nobreak-predicate' hook.

** Registers

*** All interactive commands that read a register (`copy-to-register', etc.)
now display a temporary window after `register-preview-delay' seconds
that summarizes existing registers.  To disable this, set that option to nil.
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
`frame-configuration-to-register'.  It offers similar functionality,
plus enhancements like the ability to restore deleted frames.
(`frame-configuration-to-register' still exists, but no longer has a
key binding.)

*** New command `C-x C-k x' (`kmacro-to-register') stores keyboard
macros in registers.

* Changes in Specialized Modes and Packages in Emacs 24.4

** Backtrace and debugger

*** New Lisp debugger command `v' (`debugger-toggle-locals') toggles the
display of local variables of the current stack frame.

*** The Lisp debugger's `e' command (`debugger-eval-expression') now includes
the lexical environment when evaluating the code in the context at point
(and so allows you to access lexical variables).

*** New minor mode `jit-lock-debug-mode' helps you debug code run via JIT Lock.

** Battery information can now be retrieved from BSD's `apm' utility.

** In the Buffer Menu, `M-s a C-o' shows matches for a regexp in marked buffers.

** Calc

*** Calc by default now uses the Gregorian calendar for all dates, and
uses January 1, 1 AD as its day number 1.  Previously Calc used the
Julian calendar for dates before September 14, 1752, and it used
December 31, 1 BC as its day number 1; the new scheme is more
consistent with Calendar's calendrical system and day numbering.

*** The new option `calc-gregorian-switch' lets you configure if
(and when) Calc switches from the Julian to the Gregorian calendar.

*** Support for ISO 8601 dates.

** Calendar and Diary

*** New faces `calendar-weekday-header', `calendar-weekend-header',
and `calendar-month-header'.

*** New option `calendar-day-header-array'.

*** New variable `diary-from-outlook-function', used by the command
`diary-from-outlook'.

*** The variable `calendar-font-lock-keywords' is obsolete.

** CEDET

*** EDE

**** The cpp-root project now supports executing a compile command.
It can be set through the new :compile-command slot or the
buffer-local variable `compile-command'.

**** Better selection of include directories for the 'linux' project.
Include directories now support out-of-tree build directories and
target architecture auto-detection.

*** Semantic

**** Improved detection of used namespaces in current scope in C++.

**** Parsing of default values for variables and function arguments in C/C++.
They are also displayed by the summarize feature in the mode line.

**** Improved parsing of function pointers in C/C++.
This also includes parsing of function pointers as function arguments.

**** Parsing of C/C++ preprocessor macros that open new scope.
For example, this enables parsing of macros that open new namespaces.

**** Support for 'this' pointer in inline member functions in C++.

** CFEngine mode

*** Support for completion, ElDoc, and Flycheck has been added.

*** The current CFEngine syntax is parsed from "cf-promises -s json".
There is a fallback syntax available if you don't have cf-promises or
if your version doesn't support that option.  See option `cfengine-cf-promises'.

** cl-lib

*** New macro `cl-tagbody'.
This executes statements while allowing for control transfer to labels.

*** letf is now just an alias for cl-letf.

** 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's rectangles can now be used without CUA by calling the command
`cua-rectangle-mark-mode'.

** Delete Selection mode can now be used without Transient Mark mode.

** Desktop

*** `desktop-save-mode' by default now auto-saves an existing desktop file
after `desktop-auto-save-timeout'.  To disable this, customize that option
to nil (or zero).

*** Desktop now saves and restores the frame/window configuration.
To disable this, set `desktop-restore-frames' to nil.
See also related options `desktop-restore-reuses-frames',
`desktop-restore-in-current-display', and `desktop-restore-forces-onscreen'.

** New Dired minor mode `dired-hide-details-mode' toggles whether details,
such as file ownership or permissions, are visible in Dired buffers.
See the new options `dired-hide-details-hide-symlink-targets' and
`dired-hide-details-hide-information-lines' for customizing what to hide.

** You can enable ElDoc inside the `eval-expression' minibuffer with:
  (add-hook 'eval-expression-minibuffer-setup-hook 'eldoc-mode)
The results display in the mode line.

** Electric Pair mode

*** New option `electric-pair-preserve-balance', enabled by default.
If non-nil, pairing/skipping only kicks in when that help the balance
of parentheses and quotes; i.e., the buffer should end up at least as
balanced as before.

You can further control this behavior by adjusting the predicates
stored in `electric-pair-inhibit-predicate' and `electric-pair-skip-self'.

*** New option `electric-pair-delete-adjacent-pairs', enabled by default.
In `electric-pair-mode', the commands `backward-delete-char' and
`backward-delete-char-untabify' are now bound to electric variants
that delete the closer when invoked between adjacent pairs.

*** New option `electric-pair-open-newline-between-pairs', enabled by default.
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.

** New EPA option `epa-mail-aliases'.
You can set this to a list of email address aliases that `epa-mail-encrypt'
should use to find keys.

** New ERC option `erc-accidental-paste-threshold-seconds'.
If set to a number, this can be used to avoid accidentally pasting large
amounts of data into the ERC input.

** New ERT macro `skip-unless' allows skipping ERT tests.

** Eshell

*** `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'.

*** New Eshell-Tramp module.
External su and sudo commands are now the default; the internal,
Tramp-using variants can still be used by enabling the eshell-tramp module.

** New F90 mode option `f90-smart-end-names'.

** New option `gnutls-verify-error', if non-nil, means that Emacs
should reject SSL/TLS certificates that GnuTLS determines as invalid.
(This option defaults to nil at present, but this is expected to change
in a future release.)

** Hi-Lock

*** New global command `M-s h .' (`highlight-symbol-at-point') highlights
the symbol near point.

*** New option `hi-lock-auto-select-face'.  When non-nil, hi-lock commands
will cycle through faces in `hi-lock-face-defaults' without prompting.

** Icomplete is now more similar to Ido.

*** Icomplete by default now applies to all forms of minibuffer completion.
The variable `icomplete-with-completion-tables' (now a user option)
controls this.  To restore the old behavior, set it back to
'(internal-complete-buffer).

*** You can navigate through and select completions using the keys
from `icomplete-minibuffer-map'.

*** The string that separates potential completions is now a customizable
option (`icomplete-separator').  The default is " | " rather than ",".

*** New face `icomplete-first-match'; and new options
`icomplete-hide-common-prefix' and `icomplete-show-matches-on-no-input'.

*** The option `icomplete-show-key-bindings' has been removed.

** Ido

*** An Ido user manual is now included.

*** The option `ido-use-virtual-buffers' can now take the value `auto'.
This means to use virtual buffers if the current ido input does not match
an existing buffer.

*** The variable `ido-decorations' can optionally have two new elements,
which are the brackets to use around the sole remaining completion.

** Image mode

*** New commands `n' (`image-next-file') and `p' (`image-previous-file')
visit the next image file and the previous image file in the same
directory, respectively.

*** New commands to show specific frames of multi-frame images.
`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
next or previous frame.  `F' (`image-goto-frame') shows a specific frame.

*** New commands to speed up, slow down, or reverse animation.
`a +' (`image-increase-speed') and `a -' (`image-decrease-speed') to
speed up and slow down the animation.  `a r' (`image-reverse-speed')
to reverse it and `a 0' (`image-reset-speed') to reset it.

*** 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.

** New Imenu option `imenu-generic-skip-comments-and-strings'.

** Info

*** New Info face `info-index-match', used to highlight matches in index
entries displayed by `Info-index-next', `Info-virtual-index' and
`info-apropos'.

*** The Info-edit command is obsolete.  Editing Info nodes by hand
has not been relevant for some time.

** JS Mode

*** New option `js-switch-indent-offset'.

*** Better indentation of multiple-variable declarations.
If a declaration spans several lines, variables on the following lines
are lined up to the first one.

*** Recognition and better indentation of continuations in array comprehensions.

** MH-E has been updated to version 8.6 - see separate MH-E-NEWS file.

** Octave mode

*** Font locking for Texinfo comments and new keywords.

*** Completion in Octave file buffers.

*** ElDoc support.

*** Jump to definition.

*** Documentation lookup/search.

** OPascal mode is the new name for Delphi mode

*** All delphi-* variables and functions have been renamed to opascal-*.
Obsolete aliases exist for those likely to have been used externally.

*** The option `delphi-newline-always-indents' has been removed.
Use `electric-indent-mode' instead.

*** The TAB key runs the standard `indent-for-tab-command', not `delphi-tab'.

** Package

*** The package library now supports digital signing of packages.
Maintainers of package archives should consider signing their packages
to enhance security.

**** If the user option `package-check-signature' is non-nil,
Emacs tries to check package signatures at install time.
The value `allow-unsigned' allows installation of unsigned packages.

**** The user option `package-unsigned-archives' lists archives where
Emacs will not try to check signatures.

*** New option `package-pinned-packages'.  This is useful if you have multiple
archives enabled, with more than one offering a given package that you want.

*** In the `list-packages' buffer, you can use `f' (`package-menu-filter')
to filter the list of packages by a keyword.

*** In the `describe-package' buffer, there are now buttons listing the
keywords related to the package.  Click on a button to see other packages
related to that keyword.

*** 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.
(For example, `describe-package' uses the `:url' extra property to
display a "Homepage" header.)

** In Prolog mode, `prolog-use-smie' has been removed,
along with the non-SMIE indentation code.

** Python mode

*** Out of the box support for CPython, iPython and readline based shells.
**** `python-shell-completion-module-string-code' is no longer used.

*** Automatic shell prompt detection.  New user options:
**** `python-shell-interpreter-interactive-arg'.
**** `python-shell-prompt-detect-enabled'.
**** `python-shell-prompt-detect-failure-warning'.
**** `python-shell-prompt-input-regexps'.
**** `python-shell-prompt-output-regexps'.

*** Python shell support for remote hosts via tramp.

*** Correct display of line numbers for code sent to the Python shell.

** Remember

*** The new command `remember-notes' creates a buffer that is saved on exit.
You can use it as a more permanent *scratch* buffer.

*** 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

*** Customize `rmail-mbox-format' to influence some minor aspects of
how Rmail displays non-MIME messages.

*** The `unrmail' command now converts from BABYL to mboxrd format,
rather than mboxo.  Customize `unrmail-mbox-format' to change this.

** Ruby mode

*** Improved syntax highlighting and indentation.

*** New `electric-indent-mode' integration.

*** New option `ruby-encoding-magic-comment-style'.

*** New option `ruby-custom-encoding-magic-comment-template'.

*** New option `ruby-align-to-stmt-keywords'.

*** New option `ruby-align-chained-calls'.

*** More Ruby file types have been added to `auto-mode-alist'.

** 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 whether search matches invisible text.

*** `query-replace' skips invisible text when `search-invisible' is nil,
and opens overlays with hidden text when `search-invisible' is `open'.

*** A negative prefix argument of replacement commands replaces backward.
`M-- M-%' replaces a string backward, `M-- C-M-%' replaces a regexp
backward, `M-s w words M-- M-%' replaces a sequence of words backward.

*** By default, prefix arguments do not now terminate Isearch mode.
Set `isearch-allow-prefix' to nil to restore the 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.

** New SES command `ses-rename-cell' allows assignment of names to SES cells.

** The shell.el option `explicit-bash-args' includes --noediting by default.
All non-ancient Bash versions support this option.

** Shell Script mode

*** The SMIE indentation engine is now used by default - see `sh-use-smie'.

*** `sh-mode' now has its own setting for `add-log-current-defun-function'.

** SMIE

*** You can customize the SMIE indentation of a mode via `smie-config'.
The command `smie-config-guess' can help you derive the appropriate
indentation settings, if you provide it with an indented sample file.
Use `smie-config-save' to save the result.

*** You can customize the SMIE indentation of a file by adding an entry to
the file's local variables of the form: `eval: (smie-config-local '(RULES))'.

*** New commands `smie-config-show-indent' and `smie-config-set-indent'.

** SQL mode

*** Improved login monitoring and appropriate response to login failures.
New variable `sql-login-delay' defines maximum wait time for a connection.

*** Oracle support.
SQL*Plus script placeholders are properly highlighted and identified
in `sql-placeholders-filter'.  When starting SQL*Plus, `sql-oracle-options'
are passed before the logon parameter, as required.  The default now
includes `-L', to limit the number of logon attempts per invocation.

** New Term mode option `term-suppress-hard-newline'.

** Todo mode has been rewritten and enhanced.
The Todo mode user manual describes all commands and most user
options.  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 previous version of todo-mode.el has been
renamed to otodo-mode.el and is now obsolete.  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 item types 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 many faces.

** Trace

*** `trace-function' and `trace-function-background' no longer prompt for
the output buffer.  Unless you use a prefix argument, they output to
`trace-buffer'.

*** With a prefix argument, `trace-function' and `trace-function-background'
will prompt for a "context".  This is a Lisp expression, whose value at the
time the function is entered/exited is printed along with the function's
name and arguments.

** Tramp

*** New connection method "adb", which allows to access Android
devices by the Android Debug Bridge.  The variable `tramp-adb-program'
can be used to adapt the path of the "adb" program, if needed.

*** Handlers for `file-acl' and `set-file-acl' for remote machines
that support POSIX ACLs.

*** Handlers for `file-notify-add-watch' and `file-notify-rm-watch'
for remote machines that support filesystem notifications.

*** The experimental url syntax for remote file names has been removed.

*** The connection methods "plink1", "ssh1", "ssh2", "scp1", "scp2",
"scpc" and "rsyncc" are discontinued.  The ssh option
"ControlMaster=auto" is set automatically in all ssh-based methods,
when possible.  See `tramp-use-ssh-controlmaster-options'.

** New URL command `url-cookie-list' displays the current cookies,
and allows you to interactively remove cookies.

** VC and related modes

*** In VC directory mode, `D' displays diffs between VC-controlled
whole tree revisions.

*** In VC directory mode, `L' lists the change log for the current VC
controlled tree in a window.

*** In VC directory mode, `I' shows a log of changes that will be
received with a pull operation.

*** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file
under current version control system.  When called with a prefix
argument, you can remove a file from the ignored file list.

** VHDL mode

*** New options: `vhdl-actual-generic-name', `vhdl-beautify-options'.

*** New commands: `vhdl-fix-statement-region', `vhdl-fix-statement-buffer'.

** The Woman commands `woman-default-faces' and `woman-monochrome-faces'
are obsolete.  Customize the `woman-*' faces instead.

** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.

** Obsolete packages

*** iswitchb.el; use icomplete-mode.

*** longlines.el; use visual-line-mode.

*** meese.el.

*** sup-mouse.el.

*** terminal.el; use term.el instead.

*** the old version of todo-mode.el (renamed to otodo-mode.el).

*** xesam.el (owing to the cancellation of the XESAM project).

*** yow.el; use fortune.el or cookie1.el instead.

* New Modes and Packages in Emacs 24.4

** New package eww.el provides a built-in web browser.
This requires Emacs to have been compiled with libxml2 support.

** New package nadvice.el offers lighter-weight advice facilities.
It is layered as:

*** `add-function'/`remove-function', which can be used to add/remove code on
any function-carrying place, such as process filters or `<foo>-function' hooks.

*** `advice-add'/`advice-remove' to add/remove a piece of advice on a named
function, much like `defadvice' does.

** New package frameset.el provides a set of operations to save a frameset
(the state of all or a subset of the existing frames and windows, somewhat
similar to a frame configuration), both in-session and persistently, and
restore it at some point in the future.

** New package filenotify.el provides an interface for file system
notifications.  It requires that Emacs be compiled with one of the
low-level libraries gfilenotify.c, inotify.c or w32notify.c.

** New minor modes `prettify-symbols-mode' and `global-prettify-symbols-mode'
display specified symbols as composed characters.  E.g., in Emacs Lisp mode,
this replaces the string "lambda" with the Greek lambda character.

** New minor mode `superword-mode', which overrides the default word motion
commands to treat "symbol_words" as a single word, similar to what
`subword-mode' does.

* Incompatible Lisp Changes in Emacs 24.4

** 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.

** Default process filters and sentinels are not nil any more.
Instead they default to a function that does what the nil value used to do.

** Overlay priority does not have to be nil or a non-negative integer.
Overlay priority can be other kinds of Lisp objects.  We didn't yet
decide whether other types of values are stable enough, and therefore
don't feel it's right to document them.  For now, don't assume in your
code that the values of overlay priority can only be either nil or an
integer, always test them with an appropriate predicate to be one or
the other.  If you need to sort arbitrary overlays into priority
order, `overlays-at' can now optionally do this.
You should still only specify integer priorities on overlays you create.

** The cars of the elements in `interpreter-mode-alist' are now
treated as regexps rather than literal strings.

** `overriding-terminal-local-map' no longer replaces the local keymaps.
It used to disable the minor mode, major mode, and text-property keymaps,
whereas now it simply has higher precedence.

** `kill-region' has lost its `yank-handler' optional argument.

** `(input-pending-p)' no longer runs other timers that are ready to run.
The new optional CHECK-TIMERS parameter allows for the prior behavior.

** `defvar' and `defcustom' in a let-binding affect the "external" default.

** The syntax of ?» and ?« is now punctuation instead of matched parens.
Some languages match those as »...«, and others as «...», so it is
better for Emacs to stay neutral by default.

** `read-event' does not always decode chars in ttys any more.  As was the case
in Emacs 22 and before, `read-event' (and `read-char') by default read raw
bytes from the terminal.  If you want to read decoded chars instead (as was
always the case in Emacs-23, for example), pass a non-nil
`inherit-input-method' argument.

** In `symbol-function', nil and "unbound" are indistinguishable.
`symbol-function' does not signal a `void-function' error any more.
To determine if a symbol's function definition is void, use `fboundp'.

** `defadvice' does not honor the `freeze' flag and cannot advise
special-forms any more.

** `dolist' no longer binds VAR while evaluating the RESULT form,
when lexical binding is enabled.  Previously, VAR was bound to nil,
which often led to spurious unused-variable warnings.

** The return value of `backup-buffer' has changed.
The second argument is no longer an SELinux context, instead it is an
alist of extended attributes as returned by the new function
`file-extended-attributes'.  The attributes can be applied to another
file using `set-file-extended-attributes'.

** By default `copy-file' no longer copies file permission bits to an
existing destination; and it sets the file permission bits of a newly
created destination to those of the source, masked by the default file
permissions.  To copy the file permission bits, pass t as the
PRESERVE-PERMISSIONS argument of `copy-file'.

** `visited-file-modtime' now returns -1 for nonexistent files.
Formerly it returned a list (-1 LOW USEC PSEC), but this was ambiguous
in the presence of files with negative time stamps.

** Frame-local variables that affect redisplay do not work any more.
More specifically, redisplay does not bother to check for a frame-local
value when looking up variables.

** In compiled Lisp files, the header no longer includes a timestamp.

** The option `inhibit-local-menu-bar-menus' has been removed.

* Lisp Changes in Emacs 24.4

** Change to the Emacs Lisp coding conventions: 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.

** The second argument of `eval' can now specify a lexical environment.

** New macro `define-alternatives' can be used to define generic commands.
Generic commands are interactive functions whose implementation can be
selected among several alternatives, as a matter of user preference.

** Numeric comparison functions =, <, >, <=, >= can now take many arguments.

** New functions `special-form-p' and `macrop'.

** New macro `with-eval-after-load'.
This is like the old `eval-after-load', but better behaved.

** 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'.
Directory-local variables are ignored if this is nil.  This may be
useful for modes that want to ignore directory-locals while still
respecting file-local variables.

** `read-regexp' now uses the new variable `read-regexp-defaults-function'
as a function to call to provide default values.

** New functions `group-gid' and `group-real-gid'.

** New function `get-pos-property'.

** New hook `pre-redisplay-function'.

** `byte-compile-interactive-only-functions' is now obsolete.
To specify that a command should only be called interactively, give it
a non-nil `interactive-only' property.

** New function `string-suffix-p'.

** `split-string' now takes an optional argument TRIM.
The value, if non-nil, is a regexp that specifies what to trim from
the start and end of each substring.

** Completion

*** The separator used by `completing-read-multiple' is now a regexp.
The default `crm-separator' has been changed to allow surrounding spaces
around the comma.

*** New function `completion-table-with-cache' is a wrapper for
`completion-table-dynamic' that caches the result of the last lookup.

*** New function `completion-table-merge' to combine several
completion tables by merging their completions.

*** The `common-substring' argument of `display-completion-list',
which has been documented as obsolete since Emacs 23.1, is now _really_
obsolete, and no longer advertised.  Instead either call
`completion-hilit-commonality' to add the highlighting; or use
`completion-all-completions', which returns highlighted strings.

** Encoding and decoding of text

*** New coding-system `prefer-utf-8'.
This is like `undecided' but prefers UTF-8 on decoding if the text to
be decoded does not contain any invalid UTF-8 sequences.  On encoding,
any non-ASCII characters are automatically encoded as UTF-8.

*** New attributes of coding-systems whose type is `undecided'.
Two new attributes, `:inhibit-null-byte-detection' and
`:inhibit-iso-escape-detection', determine how to detect encoding of
text that includes null bytes and ISO-2022 escape sequences, respectively.
Each of these attributes can be either nil, zero, or t.  If t, decoding
text ignores null bytes and ISO-2022 sequences, respectively.  If nil,
null bytes cause text to be decoded with no-conversion, and ISO-2022
sequences cause Emacs to assume the text is encoded in one of the ISO-2022
encodings, such as iso-2022-7bit.  If zero, Emacs consults the variables
`inhibit-null-byte-detection' and `inhibit-iso-escape-detection'.
The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer
UTF-8 encoding and decoding, whenever possible.

These attributes are only meaningful for coding-systems of type `undecided'.
(The type of a coding-system is determined by its `:coding-type' attribute
and can be accessed by calling the `coding-system-type' function.)

** Error-handling

*** New function `define-error'.

*** `with-demoted-errors' takes an additional argument `format'.

*** Errors from timer functions are no longer silently discarded,
but are reported as messages.  So you may see "Error running timer"
messages from code that was failing silently till now.  Set
`debug-on-error' non-nil to get a real error and a backtrace.

** Faces

*** Face specs set via Custom themes now replace the `defface' spec
rather than inheriting from it.  In other words, setting a face via a
theme now behaves like setting it via Customize: you only need to
specify the attributes that you want, you don't need to unset those
that you don't want.

*** The function `face-spec-set' is now like `setq' for face specs.
Its third arg now accepts values specifying a face spec type (defface,
custom, or override spec), and the relevant spec is set accordingly.

*** New face spec attribute :distant-foreground
specifies foreground to use if background color is near the foreground
color that would otherwise have been used.

*** New function `add-face-text-property', which can be used to
conveniently prepend/append new face properties.

*** New face characteristic (supports :underline (:style wave))
specifies whether or not the terminal can display a wavy line.

** File-handling

*** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files.  This requires the
`glib' API, or the 'inotify' API (on GNU/Linux systems only).  On
MS-Windows systems, this is supported for Windows XP and newer.

*** 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
platforms, and nobody seems to have noticed or cared.

*** The 6th argument to `copy-file' has been renamed to
PRESERVE-PERMISSIONS as it now handles ACL entries and the traditional
Unix file permission bits as well as SELinux context.

*** The function `file-ownership-preserved-p' now has an optional
argument GROUP which causes it check for file group too.  This can be
used in place of the 9th element of `file-attributes'.

*** The function `set-visited-file-modtime' now accepts a 0 or -1 argument,
with the same interpretation as the returned value of `visited-file-modtime'.

** 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.

*** New variable `image-default-frame-delay' gives the frame delay for
animated images which do not specify a frame delay.

*** New functions `image-current-frame' and `image-show-frame' for getting
and setting the current frame of a multi-frame image.

** ImageMagick

*** ImageMagick images now support the :max-width and :max-height keywords.

*** When using `create-image' with image data, you can pass a :format
attribute (via the property-list argument) in order to help
ImageMagick detect the image type.  The value should be a MIME
content-type that is found in the new variable `image-format-suffixes'.

** Revert and Autorevert

*** If Emacs is compiled with file notification support, it uses notifications
instead of checking file time stamps.  To disable this, set the user option
`auto-revert-use-notify' to nil.  Alternatively, you can specify a regular
expression matching directories to be excluded from file notifications via
`auto-revert-notify-exclude-dir-regexp'.

*** The default values of `buffer-stale-function', `revert-buffer-function',
and `revert-buffer-insert-file-contents-function' are no longer nil.
Instead they default to functions that do what the nil value used to.

*** `buffer-stale-function' is now used for buffers visiting files too.

*** The new user option `auto-revert-remote-files' enables reversion
of remote files, if non-nil.

** Terminal

*** Functions to pop up menus and dialogs now work on all terminals,
including TTYs.  This includes `x-popup-menu', `x-popup-dialog',
`message-box', `yes-or-no-p', etc.

The function `display-popup-menus-p' will now return non-nil for a
display or frame whenever a mouse is supported on that display or frame.

*** New hook `tty-setup-hook', run at the end of initializing a text terminal.

*** The hook `term-setup-hook' is obsolete.  It is entirely equivalent
to `emacs-startup-hook'.  See also the new `tty-setup-hook'.

** Minor internal changes to the details of lock files.
The lock for DIR/FILE is now _always_ DIR/.#FILE.
If DIR/.#FILE already exists and is not an Emacs lock file,
Emacs makes no attempt to lock DIR/FILE.  (Previously, it fell back to
numbered lock files DIR/.#FILE.0...).
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.

** New bool-vector set operation functions:
*** `bool-vector-exclusive-or'
*** `bool-vector-union'
*** `bool-vector-intersection'
*** `bool-vector-set-difference'
*** `bool-vector-not'
*** `bool-vector-subsetp'
*** `bool-vector-count-consecutive'
*** `bool-vector-count-population'

** New library subr-x.el with miscellaneous small utility functions:
*** `hash-table-keys'
*** `hash-table-values'
*** `string-blank-p'
*** `string-empty-p'
*** `string-join'
*** `string-reverse'
*** `string-trim-left'
*** `string-trim-right'
*** `string-trim'
*** `string-remove-prefix'
*** `string-remove-suffix'

** The `time-to-seconds' alias to `float-time' is no longer marked obsolete.

** The spelling of the rx.el category `chinese-two-byte' has been
corrected (the first 'e' was missing).

** EIEIO namespace cleanup, obsolete-aliasing functions to use `eieio-' prefix:
*** object-name -> eieio-object-name
*** object-class -> eieio-object-class
*** object-class-fast -> eieio--object-class
*** object-class-name -> eieio-object-class-name
*** object-name-string -> eieio-object-name-string
*** object-num-slots -> eieio--object-num-slots
*** object-set-name-string -> eieio-object-set-name-string
*** class-of -> eieio-object-class
*** class-name -> eieio-class-name
*** class-parent -> eieio-class-parent
*** class-parents -> eieio-class-parents
*** class-parents-fast -> eieio-class-parents-fast
*** class-children -> eieio-class-children
*** class-num-slots -> eieio--class-num-slots
*** class-precedence-list -> eieio-class-precedence-list
*** class-direct-subclasses -> eieio-class-children
*** class-direct-superclasses -> eieio-class-parents

** Obsoleted functions
*** `log10'
*** `dont-compile'
*** `lisp-complete-symbol'
*** `field-complete'
*** `minibuffer-completion-contents'
*** `isearch-nonincremental-exit-minibuffer'
*** `isearch-filter-visible'
*** `generic-make-keywords-list'
*** `get-upcase-table' (use `case-table-get-table' instead).

** `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'.

* Changes in Emacs 24.4 on Non-Free Operating Systems

** New Core Text based font backend for Mac OS X 10.5 and newer.
To use the old font backend, use the following on the command line:
  % defaults write org.gnu.Emacs FontBackend ns
GNUstep and Mac OS X 10.4 use the old font backend.

** Improved fullscreen support on Mac OS X 10.7 and newer, where the
default fullscreen method is now "native" fullscreen.  To use the
old style fullscreen, customize `ns-use-native-fullscreen' to nil.

** On Mac OS X 10.7 and newer, Emacs can use sRGB colorspace, and does so
by default.  Customize `ns-use-srgb-colorspace' to go back to the old method.
Note that this does not apply to images.

** The procedure for building Emacs on MS-Windows has changed.
It is now built by running the same configure script as on all other
platforms.  This requires the MSYS environment and MinGW development
tools.  See the updated instructions in nt/INSTALL for details.

Using the Posix configure script and Makefiles 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.)

** Emacs on Windows 2000 and later can now access files and directories
whose names cannot be encoded in the current system codepage.

The new variable `w32-unicode-filenames' controls this feature: if it
is t, Emacs uses Unicode APIs to pass file names to system calls,
which lifts the limitation of file names to the current locale.

** Lock files now work on MS-Windows.
This helps to prevent 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.

** The "generate a backtrace on fatal error" feature now works on MS-Windows.
The backtrace is written to the 'emacs_backtrace.txt' file in the
directory where Emacs was running.

** The `network-interface-list' and `network-interface-info' functions
are now available on MS-Windows.

** The variable `buffer-file-type' is no longer supported.
Setting it has no effect, and %t in the mode-line format is ignored.
Likewise, `file-name-buffer-file-type-alist' is now obsolete, and
modifying it has no effect.
