i was reading this article about piece evaluations, likely using stockfish 15.1, and noticed they're identical to the ones listed in the same file in stockfish 17.1 [and also that the end game values aren't listed anymore]. i'm not very familiar with stockfish, but i'd be surprised if the piece evaluations were genuinely exactly the same, so my question is just whether or not i'm parsing all of this correctly or if the current listed values are something like placeholder

Stockfish(1): Chess Piece Values

What is the value of a queen, a bishop, or a knight in chess?
There have been several attempts in the past, mainly in books to help assessing positions and taking a decision (e.g., when exchanging pieces). We’ll all agree that you should not give your queen for a pawn in general, but chess is full of subtlety and beauty! A Twitter thread nice...

yeah those

i just mean are they actually the exact same or not i would've expected them to change since 15.1 but the listing says otherwise

they aren't really used for much

#

well mjostly for material scaling

that feels decently important but i see there isn't really any reason to have them fluctuate since, then

#

also, the reason the endgame-specific values were removed (I think) is the removal of the handcrafted evaluation

#

those values were only used in that part of the code
