Erinn 1.1 is now released: https://github.com/NichtElias/Erinn/releases/tag/1.1

Should be about 200 Elo better (at 10+0.1) and lose less on time at shorter time controls

Thank you, Gabor, for taking the time to keep us informed about the latest engine releases. I really appreciate your work. Little by little, I have been downloading and testing several of these engines, and your updates are very helpful.

Kind regards,
Robert

Oh, I don't do it regularly, I only started the thread for the new half year, anybody could have done that.

Kind regards,

sorry for the inconvenience - this is not a new release, just a notification
that the recent cheng release (from late 2024) has moved
to https://github.com/kmar/cheng4_releases - so that people can fix broken links
the package is unchanged and contains zipped binaries as well as source code

the reason for this is the old repo went private
