* Installation Changes in Emacs 22.1
+---
** Emacs includes now support for loading image libraries on demand.
(Currently this feature is only used on MS Windows.) You can configure
the supported image types and their associated dynamic libraries by
M-t (transpose-words)
M-q (fill-paragraph)
++++
+** Auto Compression mode is now enabled by default.
+
+** C-x C-f RET, typing nothing in the minibuffer, is no longer a special case.
+
+Since the default input is the current directory, this has the effect
+of specifying the current directory. Normally that means to visit the
+directory with Dired.
+
+---
** fast-lock.el and lazy-lock.el are obsolete. Use jit-lock.el instead.
---
0.5 instead of 0.125. The new defaults should lower the CPU usage
when Emacs is fontifying in the background.
+---
** iso-acc.el is now obsolete. Use one of the latin input methods instead.
---
dired-ignored, dired-directory, dired-symlink, dired-warning
introduced for Dired mode instead of font-lock faces.
++++
*** New Dired command `dired-compare-directories' marks files
with different file attributes in two dired buffers.
** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is
now controlled by the variable `blink-cursor-alist'.
++++
** Filesets are collections of files. You can define a fileset in
various ways, such as based on a directory tree or based on
program files that include other program files.
** TeX modes:
++++
*** C-c C-c prompts for a command to run, and tries to offer a good default.
+++
** New command `recode-region' decodes the region again by a specified
coding system.
+---
** On Mac OS, the value of the variable `keyboard-coding-system' is
now dynamically changed according to the current keyboard script. The
variable `mac-keyboard-text-encoding' and the constants
** The new package flymake.el does on-the-fly syntax checking of program
source files. See the Flymake's Info manual for more details.
+---
** The library tree-widget.el provides a new widget to display a set
of hierarchical data as an outline. For example, the tree-widget is
well suited to display a hierarchy of directories and files.
** The thumbs.el package allows you to preview image files as thumbnails
and can be invoked from a Dired buffer.
++++
** Image files are normally visited in Image mode, which lets you toggle
between viewing the image and viewing the text using C-c C-c.
+++
** The new python.el package is used to edit Python and Jython programs.
+---
** The URL package (which had been part of W3) is now part of Emacs.
+++
position. The cursor may now be placed on any character of such
strings by giving that character a non-nil `cursor' text property.
++++
** The first face specification element in a defface can specify
`default' instead of frame classification. Then its attributes act as
defaults that apply to all the subsequent cases (and may be overridden
** `declare' is now a macro. This change was made mostly for
documentation purposes and should have no real effect on Lisp code.
++++
+** A file name handler can declare which operations it handles.
+
+You do this by putting an `operation' property on the handler name
+symbol. The property value should be a list of the operations that
+the handler really handles. It won't be called for any other
+operations.
+
+This is useful for autoloaded handlers, to prevent them from being
+autoloaded when not really necessary.
+
+++
** The new hook `before-save-hook' is invoked by `basic-save-buffer'
before saving buffers. This allows packages to perform various final
beginning. This change actually occurred in Emacs-21.1, but was not
documented.
-** Major modes can define `eldoc-print-current-symbol-info-function'
++++
+** Major modes can define `eldoc-documentation-function'
locally to provide Eldoc functionality by some method appropriate to
the language.
