The latest release you should consider downloading is here:

The main download page for Windows builds is here:

http://www.gnubg.org/index.php?itemid=56 (Sometimes updates can be frequent
so you can check this page often).

The local database (gnubg.db) is a binary file so can't be queried directly.
Gnubg uses SQL Lite for storing data in the database. SQL Lite is as the
name suggests - a light and small footprint SQL engine. If you know SQL then
things are easier.

You can query gnubg.db outside of Gnubg itself with an SQL lite tool
available here:


Documentation on its use here:


This of course is much more difficult if SQL is not something you have used
before, but I present it just in case.

The GnuBG that you download does not "learn from experience" (see pevious
posts to Roy Crabtree on that subject). If you install the new version
overtop of the old version (The old one being April 2009)- the new version
will try to use all the previous settings, and keep the database intact.
