*** Calling `delete-file' or `delete-directory' with a prefix argument
now forces true deletion, regardless of `delete-by-moving-to-trash'.
++++
** New option `list-colors-sort' defines the color sort order
for `list-colors-display'.
This is handy for minibuffer-only frames, and is also used for the "mouse-1
pops up *Messages*" feature, which can now easily be changed.

-** `tooltip-use-echo-area' is obsolete.
-Rather than setting this to t, disable Tooltip mode instead.

* Editing Changes in Emacs 24.1
** Eshell changes
-*** The default value of eshell-directory-name is a directory named
-"eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
-exists, that is used instead.
+---
+*** The default value of `eshell-directory-name' has changed
+to be an "eshell" directory in `user-emacs-directory'.
+The old "~/.eshell/" directory is still used if it exists, though.
** gdb-mi
+++
-*** GDB User Interface migrated to GDB Machine Interface and now
-supports multithread non-stop debugging and debugging of several
-threads simultaneously.
-
-** In ido-mode, C-v is no longer bound to ido-toggle-vc.
-The reason is that this interferes with cua-mode.
+*** The GDB User Interface has been migrated to GDB Machine Interface.
+It now supports multithread non-stop debugging and simultaneous
+debugging of several threads.
** Image mode
-*** RET (`image-toggle-animation') toggles animation, if the displayed
-image can be animated.
-
-*** Option `image-animate-loop', if non-nil, loops the animation.
-If nil, `image-toggle-animation' plays the animation once.
++++
+*** RET (`image-toggle-animation') toggles animation, if applicable.
+Animation plays once, unless the option `image-animate-loop' is non-nil.

of the header line.
-** Removed obsolete name `e' (use `float-e' instead).
-
** A backquote not followed by a space is now always treated as new-style.
-** Test for special mode-class was moved from view-file to view-buffer.
-FIXME: This only says what was changed, but not what are the
-programmer-visible consequences.
+---
+** view-buffer now treats special mode-class in the same way that
+view-file has since Emacs 22 (ie, it won't enable View mode if the
+major-mode is special).
** Passing a nil argument to a minor mode function now turns the mode
ON unconditionally.

+text properties from the final result, has been removed.
+Eg simply pass the result through substring-no-properties if you need this.

* Lisp changes in Emacs 24.1
++++
** Code can now use lexical scoping by default instead of dynamic scoping.
The `lexical-binding' variable lets code use lexical scoping for local
variables. It is typically set via a file-local variable in the first
line of the file, in which case it applies to all the code in that file.
-
++++
*** `eval' takes a new optional argument `lexical' to choose the new lexical
binding instead of the old dynamic binding mode.
-
++++
*** Lexically scoped interpreted functions are represented with a new form
of function value which looks like (closure ENV ARGS &rest BODY).
*** New macro `letrec' to define recursive local functions.
-
++++
*** New function `special-variable-p' to check whether a variable is
declared as dynamically bound.
++++
** An Emacs Lisp testing tool is now included.
Emacs Lisp developers can use this tool to write automated tests for
their code. See the ERT info manual for details.
** New hook types
++++
*** New function `run-hook-wrapped' for running an abnormal hook by
passing the hook functions as arguments to a "wrapping" function.
+Like `run-hook-with-args-until-success', it stops at the first
+non-nil retun value.
+
+++
*** New macro `with-wrapper-hook' for running an abnormal hook as a
set of "wrapping" filters, similar to around advice.
+(A version of this macro was actually added in Emacs 23.2 but was not
+advertised at the time.)
-** `server-eval-at' is provided to allow evaluating forms on different
-Emacs server instances.
++++
+** The macros `condition-case-no-debug' and `with-demoted-errors' were
+added in Emacs 23.1, but not advertised.
+
++++
+** The new function `server-eval-at' allows evaluation of Lisp forms on
+named Emacs server instances, using TCP sockets.
-** `call-process' allows a `(:file "file")' spec to redirect STDOUT to
-a file.
++++
+** `call-process' and `call-process-region' allow a `(:file "file")' spec
+to redirect STDOUT to a file.
---
** Variable `stack-trace-on-error' removed.
** The function format-time-string now supports the %N directive, for
higher-resolution time stamps.
++++
** New function `read-char-choice' reads a restricted set of characters,
discarding any inputs not inside the set.
++++
** `image-library-alist' is renamed to `dynamic-library-alist'.
The variable is now used to load all kind of supported dynamic libraries,
not just image libraries. The previous name is still available as an
as-is; and syntax-propertize-rules which provides a new way to specify
syntactic rules.
++++
** New hook post-self-insert-hook run at the end of self-insert-command.
+++
** Syntax tables support a new "comment style c" additionally to style b.
+---
** frame-local variables cannot be let-bound any more.
** Major and minor mode changes
*** `prog-mode' is a new major mode from which programming modes
should be derived.
++++
**** `prog-mode-hook' can be used to enable features for programming
modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
on-the-fly spell checking for comments and strings.
++++
*** New hook `change-major-mode-after-body-hook', run by
`run-mode-hooks' just before any other mode hooks.
-*** Enabled globalized minor modes can be disabled in specific modes,
-by running (FOO-mode-hook 0) via a mode hook.
++++
+*** Enabled globalized minor modes can be disabled in specific major modes.
+If the global mode is global-FOO-mode, then run (FOO-mode -1) in the
+major mode's hook, where FOO-mode toggles the mode on a per-buffer basis.
++++
*** `define-minor-mode' accepts a new keyword :variable.
+++
both non-nil. Interactively, TRASH defaults to t, unless a prefix
argument is supplied (see Trash changes, above).
+---
** `facemenu-read-color' is now an alias for `read-color'.
-The command `read-color' now requires a match for a color name or RGB
-triplet, instead of signaling an error if the user provides a invalid
-input.

** Tool-bars can display separators.
Tool-bar separators are handled like menu separators in menu-bar maps,
i.e. via menu entries of the form `(menu-item "--")'.
** Image API
++++
*** Animated images support (currently animated gifs only).
++++
**** `image-animated-p' returns non-nil if an image can be animated.
++++

is being animated.

** Isearch

*** New hook `isearch-update-post-hook' that runs in `isearch-update'.
+++
with a nil or omitted VALUE argument, the reporter message is
displayed with a "spinning bar".
++++
** New variable `revert-buffer-in-progress-p' is true while a buffer is
being reverted, even if the buffer has a local `revert-buffer-function'.
** keymaps can inherit from multiple parents.
-** `debug-on-event' lets you debug Emacs when stuck because of inhibit-quit.
++++
+** Set `debug-on-event' to make Emacs enter the debugger e.g. on receipt
+of SIGUSR1. This can be useful when `inhibit-quit' is set.
+++
-** New reader macro ## which stands for the empty symbol.
+** New reader macro ## that stands for the empty symbol.
This means that the empty symbol can now be read back. Also, #: by itself
(when not immediately followed by a possible symbol character) stands for
an empty uninterned symbol.
** Obsolete functions and variables
+---
+*** `tooltip-use-echo-area' is obsolete.
+Rather than setting this to t, disable Tooltip mode instead.
