There is a new (?) Stockfish out, Stockfish 7 beta....how good, or if it is any better than the last Stockfish 6 dev I myself have no idea, I would assume that as they have given
it the new Stockfish 7 title they must consider it an improvement.

It is the first beta version, a prototype. My guess is they will release three beta versions (beta 1, beta 2, beta 3) then release the final version at the new year.

I would have said that ever few days there is a new prototype, they call them the latest dev....wonder how long it will take all the clone makers to catch up.

NOW ! release SF7

Overall gain elo to stockfish 6?

Supposedly about 60 Elo.

Thanks Graham

I think some of the SF clones were already stronger than SF 7 prior to its release.

Well the main clone of course is Super (which I like myself) however from the tests I have seen so far it is not that much better than Fish7, and all the clones
are behind in LTC against Dragon 9.3. But you pay your money...(or get it free!!) and make your choice!?
