yes, there is a new compilation every day but the engine is starting to get slowed down as a result. Depth is deeper but NPS is much slower (-150,000) which results in far fewer wins. Plus, most of these versions crash in testing.

Fix a shift overflow warning
Visual Studio 11 is worried that shift result could
overflow an integer, this is impossible becuase max
value of the shift is 4, but compiler cannot know it.
No functional change.
Micro-optmize castling moves
Pre compute castle path so to quickly test
for impeded rule.
This speeds up perft on starting position
of more than 2%.
No functional change
