stockfish 7

[Modern Times]

i would like to ask about sf 7 release date,depends on what:specific date?
or specific elo gain?(how much elo) tx.

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.

[Dirt]

I think it will be released after TCEC 8.

If it wins that could be a good idea.

[JJJ]

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.

[A Distel]

i would like to ask about sf 7 release date,depends on what:specific date?
or specific elo gain?(how much elo) tx.

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:

cos iam interesting for android version (droidfish or official android version)

Here are android ARM compiles for the latest development version of stockfish:

Thx for offering us this compiles.

But they didn´t run on droidfish 1.57 with the device Lenovo Tab 8S with Intel Atom 3745 CPU and OS Android 4.42.

Thx for futher help.

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?
