The changes are :

Fixed the bug that cause random crashes during endgame (thanks Ingo)
Fixed time manager bug that occurs on long time control
Fixed an annoying bug that "freeze" the engine at 7ply on certain positions
Tuned evaluation
Tuned the limit strength feature (too weak compared to the elo settings)
Fixed misevaluation due to pawn blockages on some positions
Lol, amazing, after so many bug fixes, it still has crashes like 1.2b before. It seemed that all the bugs have been fixed in 1.2c, but it is not true, the engine is still buggy like hell. :D
There is still an annoying bug with WindowsXP 64bit and WindowsServer 64bit.

For my LS-ratinglist I use Windows 7 Home Premium (as you can see on the "conditions"-site on my website) and I still have some crashes with version 1.2c under the LittleBlitzerGUI (one per 1000 games, like version 1.2b).
And after 2500 games version 1.2c was 30 Elo weaker than 1.2b...

I doubt the "OS" reasoning I think it is a problem when playing chess ... I mean real chess - both sides thinking at the same time (not the smaller sub-set variant some seem to be satisfied with).
Additionaly I think the problem is increasing with longer time controls - but that is just gut feeling.

The problem is inside the time manager and occours with more frequency when ponder is on.....Ingo you're right !!!
