Since the Stockfish derivates are now built with large embedded networks the resulting download is bigger. This website uses the Responsible Download Technology® : you can download only the version related to the operating system you are using when browsing here. This was done to prevent waste of bandwidth and people downloading programs just to throwing them in the trash.

I think there was a common misunderstanding: in order to get access to this part of the site you are not forced to buy the Membership or the Subscription, just a 10$ Player Profile order or a minimum 5$ donation is sufficient (top of the page). In this way ANYONE will have a program to play for sure (free programs), but professional players or people wanting the top of the cake contribute to the costs of the site. Once again, I'm not selling programs, I'm limiting the access to the new compiles, not greedy but smart.

A note about this new engine: I got a reply from Ivan Ivec on GitHub: since version 2 CorChess will be optimized for correspondence chess only. Any binary of this particular edition is embedded with the nnue network, in this case a very heavy one. I can see because of this the will to get a more performant engine making quality moves on long times instead of a faster engine but less strong on such times. I didn't have tested it at all, though.
