There are also new packages for GNU/Linux distributions available including 3d-support and some optimizations:

OpenSuSE: built on OpenSuSE-10.1
RedHat/Fedora: 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.

Two versions of GnuBG are currently available:

• current MAIN (CVS tag MAIN, current version 0.90): most recent source code.
  • install archive (with multi-thread executables, code snapshot 20080624)
  • multi-thread executables only (win threads, code snapshot 20080624)
  • single-thread executables only (code snapshot 20080624)

• the old 0.15-stable (CVS tag rel_0_15): stable, but outdated. Us enly ni case of troubles with the most recent version.
  • install archive (code snapshot 20061119)
  • exes only

Sources are available here. For all MS Windows distributions and exes click here.

Note: the archives from 20080425 on have the new GNUbgID indicator replacing the "old" PosID and MatchID. New one is concatenetion of old ones spearated by a dot (.). HTML output is not changed for the moment (for backward compatibility), since you can paste in the new ID the old ones as they are (were): for example, you can paste this: "Position ID: yDPxADHgc+QBUA Match ID: cAlgAQAAEAAA" and it will work just fine (the code will try to smartly extract the relevant information and build the new GNUbgID from that).

Note: the archives from 20080417 on have the gnubg version number update to 0.90 (from 0.16). This may imply that, when installing the archive, it will not automatically detect your current gnubg installation. Still, you can manually install in the same directory. Notice also that, from install archive 20080417, when unistalling you will be prompted to remove or leave the .gnubg directory (it contains your settnigs and the relational dBs).

Note: install archive now comes with multi-thread executables. Single-thread executables are provided separately (for debug purposes). With multi-thread, to set the number of threads (normally equal to the number of processors/cores you have), use "Settings/Options/Others/Eval threads" in the GUI version, or "set threads" in the CLI version.

Note: due to recent changes to the relational database feature, you should use an install archive no older than 20080221. Older installation are not compatible with executables from 20080221 on (as far as relational dBs are concerned).

Note: in case of problems with older MS Windows versions (i.e. 98, ME), try this older gnubg installation archive.

Here's some instructions that allow you to build the latest version of gnubg on MS Windows. It is mainly aimed at people wanting to develop or test gnubg. [Read more]

Getting started with GNUBG, A guided tour. Zorba (Robert-Jan Veldhuizen) has written a good tutorial for GNU Backgammon at GammonLife. If you need an introduction to GNU Backgammon and how to analyse your games and matches, this introduction is great. Thanks Zorba.

I've just recieved a email from abuse@gnubg.org. The subject of the email is "Account Alert".

Hi all,

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 (359Kb).

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).

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 Italian site Non Ti Pago has released a web page featuring a download of GNU Backgammon (for Windows) together with a translation to Italian. The page is linked here. If you're only interrested in the translated manual (in PDF), it can be found here.

Thanks alot!
