Promising engines 3000+ ELO not Stockfish derivatives

Hi, chess engines enthusiasts!
In this topic we discuss about all the newest ORIGINAL engines open source and freeware!
I think that for evaluating their strengh, a blitz between ALL top engines is better that games between 2 versions of the same engine or matches beteween engines with approximately the same strengh. Here 3600+ ELO champions compete against 3000+ ELO challengers! All comments are welcome
I'll add PGN files of all the games played on my SuperBlitz always updated with latest releases.
Best regards, Alex

DR0FA 2.3.0 by the Russian Alexander Litov 3100+ ELO
SuperBlitz PGN games:

https://github.com/justNo4b/Drofa/releases/tag/3.2.0
forum3/viewtopic.php?f=2&t=75744&sid=1d ... 7b4d12e8c8
The most important changes:
Rewrite of history bonuses (now they are capped, plus other tweaks)
Added capture history
Added countermove history
Added late capture extension
Scale evaluation based on winning side pawn count
Adjust some of the extensions if null move failed
Scale evaluation for OCB + Rook / Knight endgames
Some evaluation tweaks / a couple of new eval terms
Much more agressive LMP, LMR and SEE
Retuned evaluation with Drofa data (got ~ -7 elo from this, but IMHO tuning on own data worth it)
As usual, all changes with est. elo-gain can be seen in Drofa-changelog on github
Please notify me if I fucked up windows compiles again
, hopefully i am not...
There are still many ways to improve Drofa, hopefully by the end of a year I`ll manage to crap another +100 for a release

You know, before i started visiting this forum, i imagined chess programmers as being smart and polite people, that enjoy their hobby and want to share it with others. But damn, i couldn't have been more wrong. There's more drama and toxicity here than i could've ever imagined. It's truly astounding.

Alex is a nice guy who loves computer chess, and has created this topic with great detail and care.
Thx for speaking up and expressing that which many readers of this forum are scared to do...for fear of personal attack from the many haters.

This forum is hardly representative of most engine developers. Most don't partake in discussions on this forum, avoiding it due to the very drama and toxicity you mention. I've generally found top engine developers to be mostly smart, polite people. Of course, there are exceptions, but your average engine developer is far more reasonable than your average active TalkChess user.
Regardless, I don't exactly see the point of this thread. There already exist many engine lists and threads for announcing engines/updates (we should have a separate subforum for this imo). Maybe, if Alex shared a spreadsheet with links to engines, that would be more useful/understandable. As it stands, duplicating release notes from GitHub to create separate posts for a large number of engines just serves to create more noise in my opinion.
