This is the latest version of Sting which replaces 4.7 which was previously compiled by Jim Ablett and posted here as well.
Sting is a Stockfish derivative, forked from SF 2.3.1 by Marek Kwiatkowski from Poland. It's regularly updated since the beginning. I guess it will get much stronger in time. Today it has almost 3100 ELO on CCRL scale.
Android? You can follow Rapidroid for that. Sting 4.8.4 will be very soon called for duty.
