Biggest change is that evaluation parameters are now optimized using generic gradient descent. Additionally, piece square tables are now dependent on the enemy and own king position (one piece square table for each of the 64 squares the enemy king could be on and one piece square table for each of the 64 squares our own king could be on). I also added (and removed) some other evaluation features.
Self-play improvement for 40 seconds + 0.3 seconds on a fast CPU is around 140 Elo, few tests against two other engines (Raven 1.10, Loki 3.0) indicate that true improvement is closer to 90 Elo.
Thanks for the new Greko Vladimir. Unfortunately I don't see any Threads option in Greko params. There is only a Hash option... Are you sure it is supporting MP ?

Do you see "Threads" option in reply to "uci" command in console mode?
It should look like this:
GreKo 2021.06 MP (30-June-2021)
White(1): uci
id name GreKo 2021.06 MP
id author Vladimir Medvedev
option name Hash type spin default 128 min 1 max 4096
option name Strength type spin default 100 min 0 max 100
option name Threads type spin default 1 min 1 max 4

And now the engine stopped responding when trying and play a game in Infinity GUI after 7 moves... was about to run out of time. Was trying it whitout a book.. In Fritz GUI it play with no problems with a book.

Also tried it in Infinity GUI and it showed no Threads param... is nothing surprising as always when it comes to that GUI...
Never tested with this GUI.
In Arena, Winboard/XBoard and Cutechess-Cli it works OK.
Yes, currently only 4 threads are supported.
Number of nodes is reported only for the main thread.
