Lc0 v0.18.0-rc1 has been released.

The release candidate of a new Leela version has been released:


We expect testing phase to last around 7-10 days, after which proper v0.18.0 will be released.

Download and full changelog here. Please test it thoroughly and report any bugs that you find.

Please don’t use release candidates to generate training games. We only use stable versions for that.

Change highlights:

  • Full Syzygy tablebase support (both WDL and DTZ) (read here for more context what it is).
  • MultiPV support is added.
  • Time management is optimized. Leela should take more time in first half of the game now, and insta-move rarer.
