I've released a new version of Seer here: https://github.com/connormcmonigle/seer ... tag/v2.1.0. Seer v2.1.0 is expected to be +70 to +100 elo stronger in self play against v2.0.1, though I'm rather pessimistic about how those gains will translate to other opponents. Many thanks to all OpenBench contributors for making Seer's development possible.

The executable shows v2.0.1 (a months ago release).
