Each hot championship is a source for new public demands. Since TCEC-8 has started last month, chess freaks didn't stop asking for a new release of Stockfish. Version 6 was released months ago and development version have already progressed a lot, although it's not yet considered enough to release an official update.
On the other side on the medallion, Komodo 9.2 has already fulfilled the expectations so far during TCEC-8. The reptile currently leads the Stage-2 ahead of the fish, somehow making me smile because i still remember the speculations stating that TCEC had to be delayed by the organisers just to make sure a recent version of Komodo stronger enough to cope with the latest Stockfish version becomes available.
Be it true or not, the tournament is in place, running at full speed and i'm not too concerned about possible commercial timings and manipulations. Both teams deserve respect, no matter the status, commercial or open source.
Computer chess can't progress without competition after all. Besides, i wish there could be more candidates to chase the leaders. Unfortunately there's only two engines and all others following far behind. Isn't it sad to see Houdini 4 still playing for 3rd place after so long time?
Regarding Android side of the two musqueeters on top, Komodo 9.2 is already available while Stockfish-6 was the latest among the fishes, until i heard of an alternative development version compiled by Peter Österlund, the author of Droidfish and his own engine Texel.
I see no reason for that development version play weaker than v6, given that Peter's previous compiles performed very well and that it's based on arm7 or 8 already.
I will schedule a head-to-head match between that dev't version and v6 to see what's the gap as soon as i can. Rapidroid ranking will wait for an official release anyway, regardless of the result.
Meanwhile you may download the package which includes all possible versions compiled and test for yourself: HERE
