Peacekeeper v1.40 Release

https://github.com/Sazgr/peacekeeper/releases/tag/v1.40

This release is 91.9 elo stronger in selfplay, and 56 elo stronger in a gauntlet.

I like your estimations.

PS. But I'd prefer if the engine displayed v1.40 (not 1.4) or the announcements talked about v1.4, not 1.40.

Hi,

Be grateful.
Many years ago, people were happy with a 30 Elo increase.

Hi, sorry about the version numbers being incorrectly displayed. I have attached a new fixed executable (which displayed 1.40) and it also has been fixed for any future releases.

Thanks for the fix. I guess you made no other changes so they can be combined.

Midnight v6.0 Release

https://github.com/archishou/MidnightCh ... ses/tag/v6

This version is about to appear on the CCRL blitz list. Only we don't know what version number we should use, 6 or 6.0. We used v5 for the previous version.

[archip]

The same styling as last time works, sorry if I was inconsistent.
