Why bother ? Just use the latest SDV and you're all set !
Slow compile.
I don't think that matters much at all. A handful of Elo if that.

No Stockfish 7 until +50 ELO at least from Stockfish 6. I think Stockfish dev is around +35 ELO from Stockfish 6. So probably no release right after TCEC.
But who knows, I think TCEC will last 2 month or more so maybe.

Release date: 28 December 2015... together with Fritz 15!
Maybe someone will not know that 28 December in Spain, Hispanic America, and the Philippines, is a day for pranks, equivalent to April Fool's Day:

update: after some tests from initial position seems the latest android compile looks slower then official sf6 to reach ply 20 (sf6 41 secs /latest compile 58 secs)
specs 1 cpu at 1ghz arm9 cortex
maybe arm5 compile instead arm7?
