[mehmet123]

Kayra and Stockfish evalution codes are at the crossroads. No evaluation patches added to Stockfish in the last 4-5 months have been added to Kayra codes. There are also changes in the search codes, but I won' t say that these are radical changes. During the development process of Kayra, I made radical changes in search codes but Kayra lost more elo than I thought.
Kayra is a Stockfish based engine and uses the same net as the latest version of Stockfish so it is very difficult to get a low rate in a similarity test without using a new structure net. Developing a new and different net requires time and a very powerful hardware. For now, I don't have either of these.

I think that the correct claim is that no classical evaluation patches have been added to Kayra's codes in the last 4-5 months but changes in the classical evaluation almost change nothing of stockfish's strength when stockfish use mainly its NN for evaluation and not the classical evaluation.

Changing the net that stockfish is using is an evaluation patch from my point of view.

The situation is not as you say. For example these evalution patches tested with NNUE: TRUE and all of them are green patches.

Evalution codes like these are not included in Kayra.

Because I detected important bugs affecting game power in Kayra 1.2, ı decided to publish Kayra 1.3 much earlier than I planned.

Thanks to everyone who contributed to the development of such a powerful chess engine as Stockfish and thanks to everyone who contributed to adapting the polyglot opening books to Stockfish.
