Almost, but not quite. I have fixed a few little bugs I discovered while adding the parallel search code, and probably also added a few new bugs in the process. I don't think the new version will be measurably stronger than Glaurung 1.0.2 when running on a single CPU, though. In fact I will probably recommend single CPU users to continue using version 1.0.2 even after the new version is released. Tord
