I'm also interested. It has three major changes: 1. Deep Blue search extension bound, two consecutive plies can't extend more than 2 plies, rather than any single ply being limited to extending 1 ply. 2. New EvaluateWinner() endgame module that does a better job (certainly not perfect yet) of assessing whether a game is a draw, can be won by white or black, or by both. 3. More stability in the endgame search. Whether it is stronger or not is a real question. items 2 and 3 are definitely better than before. Item 1 is a question at the moment. It also seems better, but more data is needed.
