Rotor 0.7 released

After a break from computer chess, I've caught the bug again, and have updated my program.
The new version can be found at
https://sites.google.com/site/chessrotor/
Changes since the previous version are:
- continued refactoring of code
- added support for OS X
- castling bug corrected
- tuned pawn evaluation weights using CLOP
I tried tuning other evaluation weights using CLOP, but failed so far.
This may have something to do with badly reproducable testing results that I'm looking into.
Have fun,
Jan

I will add it to my todo list, it should not be too difficult to implement.

Yes, I am!
Before Rotor even promoted to 2nd division, now it is struggling to stay in 4th division.
Many of the mid-level engines have made good progress in the last year.

The difference between version 0.4 and 0.6 is about 110 ELO points according to CCRL.
I expect 0.7 adds a few tens of points, so perhaps (fingers crossed) about 150 ELO points in total.
