Stockfish 7

[Graham Banks]

http://stockfishchess.org/download/ has been updated.

It contains the currently fastest known binaries for Stockfish 7.

Thanks to the Stockfish team.

will be android version? and compiled by whom?

Stockfish Team doesn't maintain Android version.

However Peter Osterlund (who maintains Droidfish Android app which based on Stockfish) confirmed that Stockfish 7 compiled fine for him.

So the next version of Droidfish app is likely to contain Stockfish 7.

ok its fine, but again why not from official https://stockfishchess.org/download/ ??
sf6 for android and mac was from there.droidfish etc are 3rd parties soft

When will the IOS (Apple App Store) version be updated? The version there is dated Oct 29, 2014.

Thanks!

DroidFish 1.60 which contains Stockfish 7 has been pushed to google play. If you don't want to wait for it to appear there, you can get the same version here:

If you want a standalone android binary, you can rename DroidFish.apk to DroidFish.zip, unpack it, and get the binary from the assets folder.

There are 11 different binaries. The one called stockfish-armeabi-v7a corresponds to the current version 6 binary available on the stockfish web site. If you want to compile yourself you need this patch.

The "modern" version for Windows, is that Abrok Stockfish 7beta 2?

Sorry, I can't understand your question. To download Stockfish 7, just go to http://abrok.eu/stockfish/ and download the latest version.

The binaries will likely also be available from the official website in a few hours...

What I meant was that I was following the Stockfish team's discussion about the final binaries, and I was wondering whose binary did they choose for the "modern" version, aka POPCNT.

The http://stockfishchess.org/ is now updated with SF7. POPCNT version seems same as Abrok.

The official compiles won't run under ChessGUI, yet the two beta versions did.
Oddly enough, the Stockfish 7 compiles from the Abrok site work fine.

Stockfish 7 is out!

This release is around 60 ELO stronger than Stockfish 6 in self play.
SMP algorithm has been changed from YBW to Lazy SMP.
Gary Linscott is now officially listed as a co-author.

The official binaries will be made available from http://stockfishchess.org/ shortly.

Meanwhile feel free to use binaries from http://abrok.eu/stockfish.

If you have Windows x64 Hashwell system, the following binaries built by Kiran Panditrao perform around 5% better compared to abrok's builds:

As a side note: Stockfish 7 beta2 is functionally fully identical to Stockfish 7.
