[Help-gnutls] GnuTLS 1.5.3 - experimental

[Simon Josefsson]

I am happy to announce GnuTLS 1.5.3, a release on the current
development branch.  We still recommend the 1.4.x branch as the stable
version.

One goal with the 1.5.x branch is to make Windows x86 a supported
platform for GnuTLS.  We do this by providing a binary Windows
installer of GnuTLS, cross-compiled from GNU/Linux using MinGW and
NSIS.  The installer is (lightly) tested on Windows 2000 and Windows
XP.  It is possible to develop applications in Visual Studio or MinGW
that links to the library.  See http://josefsson.org/gnutls4win/ for
more information on the Windows releases.

GnuTLS is a modern C library that implement the standard network
security protocol Transport Layer Security (TLS), for use by network
applications.

* Version 1.5.3 (released 2006-10-26)

** Add new self-test of RSA-MD5 signature chains.
Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
when verifying X.509 chains.  The code is in tests/rsa-md5-collision/
and is based on the work by Marc Stevens et al, see
<http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.

** Re-factor self tests.

** The include copy of Libtasn1 is updated to version 0.3.7.

** The included copy of OpenCDK is updated to version 0.5.11.

** Fix the filename of the *.def file on Windows after library version bump.

** Separated the gnulib directory into one for LGPL modules and one for GPL.
This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
gnulib modules.  Earlier we could only use the LGPL'ed module from
gnulib, because two gnulib directories in the same project didn't
work.

** API and ABI modifications:
No changes since last version.

Improving GnuTLS is costly, but you can help!  We are looking for
organizations that find GnuTLS useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, or donate
money or equipment.

Commercial support contracts for GnuTLS are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding GnuTLS
maintenance.  We are always looking for interesting development
projects.  See http://josefsson.org/ for more details.
