Please don't !!!!!


These are not official releases, it is just someone that grabs the current sources and makes a compile.

Stockfish team does not support this !

I have asked Jim to not compile these active developing stuff. When we will think Stockfish will be ready for release it will be officially released with compiles by Jim, as usual. We knew there was the risk of random compiles cropping around when we chose to public the development repository on github, but nevertheless we deemed the advantages bigger than the disadvantages. I think this very clear statement by me will help clarify and possibly stop this. Of course every one is free to do whatever he wants with the sources (as long as GPL license is honored), but we have the right to say that we do not endorse this and ask testers to wait for the official ones.

Stockfish 2.2

Released 10 hours ago on December 29, 2011

To start the new year with a fresh new base I’d like to release Stockfish 2.2. This should be really a small improvement ELO wise, I have tested it against SF 2.1.1 JA and in single core I got +10 ELO, we think in multi core we should gain some more, but remain anyhow around +20 ELO maximum. Not a lot for 6 months of work but at least the readability of code base has greatly improved and also shrinked in size of almost 900 lines:

42 files changed, 3853 insertions(+), 4729 deletions(-)

This is just an “Happy New Year” release, nothing more.

It is important that the below signature matches in all the platforms:

stockfish bench signature is: 5457475

Thanks a lot and Happy New 2012 to everybody!

Marco

Update: We are having some issues compiling for Windows. For those who downloaded the Mac version yesterday, the final 2.2 release may be different.
