I have released Arasan 8.4, which is available from
http://www.arasanchess.org. This is pretty much the same version
that played in CCT7, plus a few minor fixes.
Changes in Arasan 8.4:
1) Bug fixes in pin detection
2) Scoring changes
3) Better lazy eval in scoring module.
4) Improved pawn race scoring, handles more cases.
5) More liberal use of null move in endgames (but less aggressive use
of R=3).
6) "make install" target added to Linux Makefile.
7) use feature done=0/done=1 to bracket tablebase initialization.
