*** Emacs now supports using both X displays and ttys in one session.
With an Emacs server active (M-x server-start), `emacsclient -t'
creates a tty frame connected to the running emacs server.  You can
use any number of different ttys.  `emacsclient -c' creates a new X11
frame on the current $DISPLAY (or a tty frame if $DISPLAY is not set).
124 125 126

You can test for the presence of this feature in your Lisp code by
testing for the `multi-tty' feature.

*** Emacs can now set the frame opacity.
The opacity of a frame can be controlled by setting the `alpha' frame
parameter.  This only takes effect on a compositing window manager for
145 146
the X Window System, such as Compiz, Beryl and Compiz Fusion, or on
Windows 2000 and later versions of Windows.
147 148

The alpha parameter should be an integer between 0 (transparent) and
Chong Yidong's avatar
Chong Yidong committed
149 150 151
100 (opaque), or a float number between 0.0 and 1.0.  It can also be a
cons cell (ACTIVE . INACTIVE), where ACTIVE is the opacity of an
active frame and INACTIVE is the opactity of non-active frames.
152

The variable `frame-alpha-lower-limit' defines a lower bound for the
opacity; the default is 20.

The internal encoding used for buffers and strings is now
Unicode-based and called `utf-8-emacs'.  This encoding is backwards
compatible with Unicode's UTF-8 encoding.  The internal encoding
previously used by Emacs, `emacs-mule', is still available.

During byte-compilation, Emacs 23 uses `utf-8-emacs' to write files.
As a result, byte-compiled files containing non-ASCII characters can't
be read by earlier versions of Emacs.  Files compiled by Emacs 20, 21,
or 22 are loaded correctly as emacs-mule (whether or not they contain
multibyte characters).  This takes somewhat more time, so it may be
worth recompiling existing .elc files which don't need to be shared
with older Emacsen.

** nXML Mode
This is a new mode for editing XML documents.  It allows a schema to
be associated with the XML document being edited, using Relax NG as
the schema language.  The schema is used to provide two key features:

*** Continuous validation.  nXML validates as you type, highlighting
any invalid parts of your document.

*** Completion.  nXML can assist you in entering an element name,
attribute name or data value by using information about what is
allowed by the schema in that context.

** proced.el provides a Dired-like interface for operating on processes.
Proced makes an Emacs buffer containing a listing of the current
processes (using ps(1)).  You can use the normal Emacs commands to
move around in this buffer, and special Proced commands to operate on
the processes listed.

** Remember Mode is a mode for jotting down things to remember.
Notes can be saved to a Diary file.  For details, see the Remember

table.  It can also indicate lines that extend beyond a given column,
trailing blanks, and empty lines at the start or end of a buffer.
See `whitespace-style' for more details.  The `whitespace-action' option

*** Python mode now has `pdbtrack' functionality.  When using pdb to
debug a Python program, pdbtrack notices the pdb prompt and displays
the source file and line that the program is stopped at, much the same
way as gud-mode does for debugging C programs with gdb.

*** If the gpm mouse server is running and t-mouse-mode is enabled,
Emacs uses a Unix socket in a GNU/Linux console to talk to server,
rather than faking events using the client program mev.  This C level
approach provides mouse highlighting and help echoing in the
minibuffer.

** Tramp

*** New connection methods.
The new methods "plinkx", "plink2", "psftp", "sftp" and "fish" have
been introduced.  There are also new so-called gateway methods
"tunnel" and "socks".

*** Multihop syntax has been removed.
The pseudo-method "multi" has been removed.  Instead of, multi hops
can be specified by the new variable `tramp-default-proxies-alist'.

*** More default settings.
Default values can be set via the variables `tramp-default-user',
`tramp-default-user-alist' and `tramp-default-host'.

*** Connection information is cached.
In order to reduce connection setup, information about used
connections are kept persistent in a file.  The name of this file is
defined in the variable `tramp-persistency-file-name'.

*** Control of remote processes.
Running processes on a remote host can be controlled by settings in
`tramp-remote-path' and `tramp-remote-process-environment'.

*** Success of remote copy is checked.
When the variable `file-precious-flag' is set, the success of a remote
file copy is checked via the file's checksum.

894 895 896 897
*** Passwords can be read from an authentification file.
Tramp uses the package `auth-source' to read passwords from a file, if
necessary.

*** VC now supports applying VC operations to a set of files at a time.
This enables VC to work much more effectively with changeset-oriented
version-control systems such as Subversion, GNU Arch, Mercurial, Git
and Bzr.  VC will now pass a multiple-file commit to these systems as
a single changeset.
