New Packages for GNU/Linux distributions
There are also new packages for GNU/Linux distributions available including 3d-support and some optimizations:
: built on OpenSuSE-10.1
: built on RedHat Advanced Server 4
The snapshots have been divided into two branches, a stable "rel_0_15" (rpms are built from these) and a current "MAIN" branch. The "MAIN" branch will be updated daily, the "rel_0_15" from time to time. Please note that "rel_0_15" doesn't contain any new features but only bugfixes.
Both tar.gz balls are available here

GNU Backgammon wins the 2006 Computer Olympics !!
I'm back from Torino where GnuBG has just won the 2006 Computer Olympics Backgammon "tournament", defeating its only opponent, BGBlitz by Frank Berger. Final score is 3-1 (best of 5 matches, 15pts each), with individual scores of 3-15, 16-12, 15-8 and 17-13.
Analysed matches (supremo, g11 met) can be downloaded here
For the records, BGBlitz is truly strong: it has been rated by gnubg analysis in the 4 matches as 1997.4, 2004.5 2035.1 and 2025.4 (FIBS rating) and in the first two matches, Frank used by mistake the "old" engine (winning one of them anyway).
MS Windows commandline build with SSE support
Some are asking if there is a commandline version available for MS Windows with SSE support. Yes, now there is. Download here
. This build has not been tested much, so please report if there's something wrong. I believe it should work with Tony Lezards Dueller

The last GTK+-1.3 Windows build available
Some of you have reported that there was a bug in the previous version. Cube analysis was inconsistent and gave different results each time you pressed a evaluation button. This bug has been found and fixed.
Because of this bug fix, here is the last build of GNU Backgammon for Windows based on GTK+-1.3 libraries that will ever be available from this site.
The installation archive is avaliable for download here
. You can check agains my detached signature here
. If you want the md5 checksum it should be: ff6105618d914db4bfc8e717ca820468.
The archive contains the usual stuff with the main executable of the CVS sources from Wednesday March 2nd 2005.
Windows builds to convert to GTK+ 2.6
The GTK+ libraries which GNU Backgammon use thoroughly will be updated for the windows builds found on this site. GNU Backgammon have always used GTK+ 1.3 for it's windows builds. It has be faster and smaller for this particular platform. GTK+ has been further improved and updated since that. It has become more powerful and modern at other platforms and the Windows port of GTK is now so stable that we find it suitable to upgrade the interface library also for Windows.
This means that it will be one last install archive with GTK+-1.3 in case some of you preferes GTK+-1.3. The install archive can be downloaded here
. Please test and report bugs.
New GNU/Linux packages available
you can get new rpms (built on SLES 9 and RHAS 30) and Debian packages for GNU Backgammon. These packages include the new weights file and the faster 2-ply evaluation.
