Interesting, Dann. At first glance, It looks like MP is correctly implemented.

Hi Werner,
I am working on the engine these days, and plan to release something soon. Not every release will contain changes to the chess engine though, as there are other changes I like to publish also.
I think it's best for testers not to bother with intermediate releases, but anyway I will try to detail what each release does, and if changes to the playing strength are expected or not.

Hi Alessandro,
that´s a good idea!
I too do not like to start testing a new released engine before I have enough games for the previous version.
So better wait till you are sure its much stronger now
(and we can see the differences at once and not after thousands of games)

good luck
