v.6.0
After months of development I now release 6.0.
A lot in the codebase has changed and has been rewritten, a lot of parts are now cleaner and smaller.
This version uses a neural network trained on smallbrain data. About 500 million depth 9 fens, 5% was special endgame generated data + 95% normal selfplay data.
Comparison against v5.0 at 8+0.08s.
