Lc0 v0.21.2 has been released

After quite a long delay we are releasing an update to Lc0, new version is v0.21.2.

Download here.

Changes include:

• Optimizations for GTX 16xx cards (cudnn-fp16 now works for them, even though it doesn’t give as much performance boost as for RTX cards).
• “Sticky endgames” feature (default on). This makes Lc0 play better when it sees a checkmate somewhere during the search.
• Centipawn formula has been updated, now Lc0 will show eval values more similar to what other engines show.
• Optimization for wider (more filters) neural net, for future (maybe test60) runs.
