Hi,
I have released Marvin 3.0.0. The main new feature is that Marvin now has multi-thread support using lazy smp. There are also some smaller evaluation and build improvements.
Approximate rating improvement:
1cpu vs 2.2.0: +35 elo
2cpu vs 1cpu: +35 elo
4cpu vs 1cpu: +75 elo
Release: https://github.com/bmdanielsson/marvin- ... tag/v3.0.0
