Stockfish 9 released
It seems that Stockfish 9 is now available... Did anyone test it already?

Any improvement "noticed"? (seems hard to notice anything anymore :))
We'll see what rating it reaches on CEGT lists...

Stockfish 9 released
Probably a bit early to ask if any genuine improvements are noticeable, since its just been released :)
One comment that I do remember from the recent Computer World Champs, where Houdini and Komodo made the finals, and Stockfish 8 missed out by a whisker, was that each of the programmers said that Stockfish did not convert some positions because it did not have as high a contempt factor as Houdini and Komodo.
So it is likely that for Stockfish 9, this is an area that the programmers have worked on.

FYI Development builds now have dynamic contempt.

Introduce dynamic contempt
Make contempt dependent on the current score of the root position.
The idea is that we now use a linear formula like the following to decide
on the contempt to use during a search :
contempt = x + y * eval
where x is the base contempt set by the user in the "Contempt" UCI option,
and y * eval is the dynamic part which adapts itself to the estimation of
the evaluation of the root position returned by the search. In this patch,
we use x = 18 centipawns by default, and the y * eval correction can go
from -20 centipawns if the root eval is less than -2.0 pawns, up to +20
centipawns when the root eval is more than 2.0 pawns.
To summarize, the new contempt goes from -0.02 to 0.38 pawns, depending if
Stockfish is losing or winning, with an average value of 0.18 pawns by default.
