Subject: XEmacs 21.4.12 "Portable Code" is released.
Organization: The XEmacs Project

*          XEmacs 21.4.12 "Portable Code" is released.
      "Portable Code" is the thirteenth in the OXYMORON series.

The 21.4 series is now officially the stable branch of XEmacs.  This
is my last release in this series, as I am passing on responsibility
to Vin Shelton, who manages the stable branches.  The 21.1 series is
retired; see "The Xemacs 21.1 series is retired" below for future
support plans if you need or prefer to use this release.

Relative to XEmacs 21.4.11 "Native Windows TTY Support", "Portable Code"
contains a few build fixes, mostly to support the most recent Cygwin
version of the GNU toolchain and the Intel C compiler suite.  That's it!

There is a known problem in the `revert-buffer' function.  If the
buffer is identical to the file, then several of the operations
involved in reversion are omitted, as they can be very expensive.  We
plan to address this issue in a future release, since only unusual usage
patterns are adversely affected and the changes required will be
somewhat tricky.  There are workarounds available, so if you find that
`revert-buffer' is not behaving as you expect and prefer, please
report your problem as a bug, and we will give it prompt attention.

The first release in this series, XEmacs 21.4.0 "Solid Vapor",
contained a large number of improvements and extensions to the previous
stable version, XEmacs 21.1.14.  For more information about the
OXYMORON series, see etc/NEWS, the initial release announcement

	      http://www.xemacs.org/Releases/21.4.0.html

For general information about XEmacs, the developers, and the user
community, see our home page,

		       http://www.xemacs.org/

* XEmacs 21.4.12 is "stable" software. 

At this point all the developers and our beta testers trust the 21.4
code base with all their editing needs.  Many have found it
sufficiently stable that they've moved on to the development branch
again in search of some excitement.

Of course, the usual "no warranty" disclaimer (see etc/WARRANTY,
sections 10 and 11) applies.

* The XEmacs 21.1 series is retired.

XEmacs 21.1 is the same excellent editor it always was, and if it
serves you well, there is no need to upgrade.  However, our resource
limitations force us to concentrate on supporting 21.4 as the stable
branch, and developing the next generation of XEmacs (the 21.5
series).  This means that there will be no further releases in the
21.1 series by the XEmacs Project.  If you have problems that require
changes to the C code, we will try to help you diagnose and patch up,
but this must be low priority.  We have no developers who are
intimately familiar with that code base any more.

We plan to ensure compatibility of packaged Lisp with XEmacs 21.1 for
at least the 6 months.  Packages currently compatible with XEmacs
21.1 will continue to work.  Of course, if the package depends on a
feature available only in XEmacs 21.4 or later, the package may do
nothing useful in XEmacs 21.1.  However, we will work to ensure that
such packages do not cause crashes or errors in XEmacs 21.1, but
rather fail gracefully.

Also, we will support building the packages with XEmacs 21.1.  It
should not be necessary to do anything special to build the entire
suite of packages.  Again, where features in 21.4 are critical to
building a new package, we will arrange that the build gracefully
skips such packages.

* Availability

Anonymous ftp:

             ftp://ftp.xemacs.org/pub/xemacs/xemacs-21.4

See http://www.xemacs.org/Install/.  (Note that the tarball breakdown
is slightly different from that implied for 21.1.  For 21.4, the
xemacs-21.4.12.tar.gz tarball contains the full contents of the
xemacs-21.4.12-{src,elc,info}.tar.gz tarballs.)

If you already have a 21.4.11 source tree, a patchkit is available in
xemacs-21.4.11-21.4.12.patch.gz.  This does not update .elcs or .infos,
they will be rebuilt when you make XEmacs.  If you have an earlier
version, you can repeatedly apply patchkits.

Also, if you don't have the packages yet, see

        http://www.xemacs.org/Documentation/packageGuide.html.

Windows branch and installers:

The Windows branch continues to have a few changes not yet included in
the mainline.  It is preferred to the mainline for Windows users.

Anonymous (pserver) CVS:

Anonymous CVS is available.  We are very grateful to the staff at our
host, SunSITE.dk, for a lot of help and quick reponse to all our
requests.

If you haven't used XEmacs CVS recently, we moved the repository
before the 21.4.6 release.  The repository structure is the same as
before, so it should be possible to reuse an existing checked-out CVS
tree.

Take care that your Root is set correctly to

	 CVSROOT=:pserver:cvs@cvs.xemacs.org:/pack/xemacscvs

On platforms with a Bourne shell and find available, something like

      for r in `find . -name Root`; do echo $CVSROOT > $r; done

will convert your entire tree.

Tags are also the same; to update to release 21.4.12, use the release
tag "r21-4-12".  To set a sticky tag which will always update to the
current release, use the branch tag "release-21-4".

For more details, see

             http://www.xemacs.org/Develop/cvsaccess.html

Unique branch and release tags are assigned to the Windows branch.
See Andy Piper's announcements and release notes for details.
