Devre 1.5 is out.

https://github.com/OmerFarukTutkun/Devre

First release I test because the previous one doesn't run in my cpus. The code is quite simple and the high rating is mostly due to the NNUE.

I read Vincent D.'s suggestion about not storing draw in the TT and gave it a try.
Seems to help caffeinatedpawn a bit (elo-wise).
