This release is mainly a bugfix of release 2.2, it also contains a LMR tweak which will add around 10 elo.
The bug: When the search was pondering or in infinite analysis mode, sometimes the search would return a “bestmove” prematurely. This is not correct and some GUI’s can not cope with this bug and crash (for instance the Shredder GUI).
A big thanks to Gerhard of the cegt team for noticing the bug and helping to find the cause! and a big thanks to all who take interest in rofChade.
