Quoting the author :
"I just released the new version 5.7.0 (pre-release)
Among the greatest changes we can cite:
* Ready for Winboard and UCI (explanation in file readme.txt)
* Better time control
* Static evaluation function simplified and stronger
* Estimated rating increased more or less 300 points
* It assumes winboard automatically now. Dont need to pass the
parameter "xboard" in winboard.ini file. Explanations about install at
readme.txt file.
Have fun.
Beco."
