+\f
+* New Modes and Packages in Emacs 24.4
+** 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
+ 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.
+
+* Incompatible Lisp Changes in Emacs 24.4
+
+** `defadvice' does not honor the `freeze' flag and cannot advise
+special-forms any more.
+
+** `dolist' in lexical-binding mode does not bind VAR in RESULT any more.
+VAR was bound to nil which was not tremendously useful and just lead to
+spurious warnings about an unused var.
+
+* Lisp changes in Emacs 24.4
+
+** New function special-form-p.
+** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
+text-property on the first char.
+
+** The `defalias-fset-function' property lets you catch calls to defalias
+and redirect them to your own function instead of `fset'.
+
+* Changes in Emacs 24.4 on non-free operating systems
+

+** 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

** In the Package Menu, newly-available packages are listed as "new",
and sorted above the other "available" packages by default.
** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
This minor mode replaces `toggle-read-only', which is now obsolete.
++++
** Emacs now generates backtraces on fatal errors.
On encountering a fatal error, Emacs now outputs a textual description
of the fatal signal, and a short backtrace on platforms like glibc

*** Global `M-s _' starts a symbol (identifier) incremental search,
and `M-s _' in Isearch toggles symbol search mode.
`M-s c' in Isearch toggles search case-sensitivity.
** New command `C-x r M-w' (copy-rectangle-as-kill).
It copies the region-rectangle as the last rectangle kill.
++++
** New option `yank-handled-properties' allows processing of text
properties on yanked text, in more ways that are more general than
just removing them, as done by `yank-excluded-properties'.
** CL
++++
*** CL's main entry is now (require 'cl-lib).
`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
i.e. all its definitions have the "cl-" prefix (and internal definitions use
that had to use `foo*' to avoid conflicts with pre-existing Elisp entities,
which have not been renamed to `cl-foo*' but just `cl-foo'.
-The old `cl' is now deprecated and is just a bunch of aliases that
-provide the old non-prefixed names.
+The old `cl' is now deprecated and is mainly just a bunch of aliases that
+provide the old non-prefixed names. Some exceptions are listed below.
++++
*** `cl-flet' is not like `flet' (which is deprecated).
Instead it obeys the behavior of Common-Lisp's `flet'.
+In particular, in cl-flet function definitions are lexically scoped,
+whereas in flet the scoping is dynamic.
++++
*** `cl-labels' is slightly different from `labels'.
The difference is that it relies on the `lexical-binding' machinery (as opposed
to the `lexical-let' machinery used previously) to capture definitions in
closures, so such closures will only work if `lexical-binding' is in use.
++++
+*** `cl-letf' is not exactly like `letf'.
+The only difference is in details that relate to some deprecated usage
+of `symbol-function' in place forms.
+
++++
*** `progv' was rewritten to use the `let' machinery.
A side effect is that vars without corresponding value are bound to nil
rather than making them unbound.
-** Compilation mode
++++
+*** The following methods of extending `setf' are obsolete
+(use features from gv.el instead):
+`define-modify-macro' (use `gv-letplace')
+`defsetf' (use `gv-define-simple-setter' or `gv-define-setter')
+`define-setf-expander' (use `gv-define-setter' or `gv-define-expander')
+`get-setf-method' no longer exists (see "Incompatible Lisp Changes")

*** Non-option variables are never matched in `customize-apropos' and
`customize-apropos-options' (i.e. the prefix argument does nothing for
these commands now).

+whitespace introduced by a diff.
** Dired
-
++++
*** `dired-do-async-shell-command' executes each file sequentially
if the command ends in `;' (when operating on multiple files).
Otherwise, it executes the command on each file in parallel.
-
+---
*** Typing M-n in the minibuffer of `dired-do-chmod', `dired-do-chgrp',
`dired-do-chown', `dired-do-touch' pulls the file attributes of the
file at point.

`DEL' (`dired-unmark-backward'), `d' (`dired-flag-file-deletion')
mark/unmark/flag all files in the active region.
-
++++
*** The minibuffer default for `=' (`dired-diff) has changed.
It is now the backup file for the file at point, if one exists.
In Transient Mark mode the default is the file at the active mark.
-
++++
*** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers.
The global binding for `M-=', `count-words-region' is in effect.

** Ediff now uses the same color scheme as Diff mode.
-** erc will look up server/channel names via auth-source and use the

++++
+** New option `async-shell-command-buffer' specifies the buffer to use
+for a new asynchronous `shell-command' when the default output buffer
+`*Async Shell Command*' is already in use.
+---
+** SQL mode has a new option `sql-db2-escape-newlines'.
If non-nil, newlines sent to the command interpreter will be escaped
by a backslash. The default does not escape the newlines and assumes
that the sql statement will be terminated by a semicolon.
** Tabulated List and packages derived from it
-
++++
*** New command `tabulated-list-sort', bound to `S', sorts the column
at point, or the Nth column if a numeric prefix argument is given.

*** Remote processes are now supported also on remote Windows host.
** URL
-
++++
*** Structs made by `url-generic-parse-url' have nil `attributes' slot.
Previously, this slot stored semicolon-separated attribute-value pairs
appended to some imap URLs, but this is not compatible with RFC 3986.
So now the `filename' slot stores the entire path and query components
and the `attributes' slot is always nil.
-
++++
*** New function `url-encode-url' for encoding a URI string.
The `url-retrieve' function now uses this to encode its URL argument,
in case that is not properly encoded.

*** New display action alist entries `window-height' and `window-width'
to specify size of new window created by `display-buffer'.
in Emacs 24.1:
+++
**** `display-buffer-reuse-frames'
++++
**** `special-display-regexps'
++++
**** `special-display-frame-alist'
++++
**** `special-display-buffer-names'
++++
**** `special-display-function'

**** `dired-shrink-to-fit'
** Time
*** `current-time-string' no longer requires that its argument's year
must be in the range 1000..9999. It now works with any year supported
by the underlying C implementation.
----
++++
*** `current-time' now returns extended-format time stamps
(HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds.
PSEC is typically a multiple of 1000 on current machines. Other
[TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS].
The PSECS slot is new, and uses picosecond resolution. It can be
accessed via the new timer--psecs accessor.
++++
+*** 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).
+++
** Floating point functions now always return special values like NaN,
on others. The affected functions are acos, asin, tan, exp, expt,
log, log10, sqrt, and mod.
-** Interpreted files are eagerly macro-expanded during load.
++++
+** Emacs tries to macroexpand interpreted (non-compiled) files during load.
This can significantly speed up execution of non-byte-compiled code,
-but can also bump into harmless and previously unnoticed cyclic
-dependencies. These should not be fatal: they will simply cause the
-macro-calls to be left for later expansion (as before), but will also
-result in a warning ("Eager macro-expansion skipped due to cycle")
-describing the cycle.

+You may wish to restructure your code so this does not happen.
** Miscellaneous new functions:
-
-*** `autoloadp'
-*** `autoload-do-load'
++++
+*** `autoloadp' tests if its argument is an autoloaded object.
++++
+*** `autoload-do-load' performs the autoloading operation.
+++
*** `buffer-narrowed-p' tests if the buffer is narrowed.
++++
*** `file-name-base' returns a file name sans directory and extension.
++++
*** `function-get' fetches a function property, following aliases.
+++
*** `posnp' tests if an object is a `posn'.
-*** `set-temporary-overlay-map' sets up a temporary overlay map.
++++
+*** `set-temporary-overlay-map' sets up a temporary keymap that
+takes precedence over most other maps for a short while (normally one key).
+++
*** `system-users' returns the user names on the system.
+++
*** `system-groups' returns the group names on the system.
++++
*** `tty-top-frame' returns the topmost frame of a text terminal.
++++
** New macros `setq-local' and `defvar-local'.
++++
** New fringe bitmap `exclamation-mark'.
++++
** Face underlining can now use a wave.
-See the "Face Attributes" section of the Elisp manual.
** The following functions and variables are obsolete:
-
-*** `automount-dir-prefix'
+---
+*** `automount-dir-prefix' (use `directory-abbrev-alist')
++++
*** `buffer-has-markers-at'
+---
*** `macro-declaration-function' (use `macro-declarations-alist')
-*** `window-system-version'
+---
+*** `window-system-version' (provides no useful information)
+---
*** `dired-pop-to-buffer' (use `dired-mark-pop-up')
+---
*** `query-replace-interactive'
+---
+*** `font-list-limit' (has had no effect since Emacs < 23)

* Changes in Emacs 24.3 on non-free operating systems
-+++
-** On MS Windows, you can pass --without-libxml2 to configure.bat to omit
-support for libxml2, even if its presence is detected.
-
-** When invoked with the -nw switch to run on the Windows text-mode terminal,
-Emacs now supports mouse highlight, help-echo (in the echo area), and
-`mouse-autoselect-window'.
+---
+** Cygwin builds can use the native MS Windows user interface.
+Pass --with-w32 to configure. The default remains the X11 interface.
** Two new functions are available in Cygwin builds:
`cygwin-convert-path-from-windows' and `cygwin-convert-path-to-windows'.
These functions allow Lisp code to access the Cygwin file-name mapping
machinery to convert between Cygwin and Windows-native file names.
+** When invoked with the -nw switch to run on the Windows text-mode terminal,
+Emacs now supports mouse highlight, help-echo (in the echo area), and
+`mouse-autoselect-window'.

++++
+** On MS Windows, you can pass --without-libxml2 to configure.bat to omit
+support for libxml2, even if its presence is detected.
+
+---
+** On Mac OS X, the Nextstep port requires OS X 10.4 or later.
+
+---
+** On Mac OS X, configure no longer automatically adds the Fink /sw
+directories to the search path. You must add them yourself if you want them.
