- Code: Select all
---------------------- 2005/12/23 version 4.3 ----------------------
Chess:
* Playing strength now scales well through all time controls
* Time usage extended for problematic positions
* Opening book improved by manually removing blunder moves and poor
lines, and manually adding some selected missing lines -- some of
these lines go quite deep
Internal:
* Hash replacement logic changed
* Hash aging changed
* Fewer compiler warnings
Optimizations:
* Search speed increased up to 2x faster (move ordering improvements)
Features:
* Removed fail-high/ fail-low indicators from score (illegal according
to the WinBoard specification although they didn't seem to cause any
problems) and added the indicators to pv instead where they are more
visible
Bugfixes:
* Fixed time-loss bug
* Fixed bug causing random moves during long time-control games
