Arasan 7.4 has been released and is available from http://www.arasanchess.org.
This is pretty close to the same engine that played in CCT6. I have made some
opening book changes and a few fixes since then, but mostly in the user
interface, not the engine.
Changes in Arasan 7.4:
1) King safety and knight centrality scoring fixes (knight centrality
was actually backwards - White table was used for Black).
2) Speed improvement: routine wouldCheck handles more cases, allowing
more cases of forward pruning before doMove.
3) Fix GUI bug re "hint" being given for the wrong side.
4) Fix GUI bug: next/previous game could crash if engine reply comes
after the command.
5) Fix GUI bug: takeback while engine is searching could sometimes
result in pieces changing color and other strange behavior.
6) GUI: Fix some BoundsChecker errors/warnings.
7) A new "options.book_enabled" flag is in arasan.rc: setting this
false disables the opening book.
8) Fix Linux spec file so it can build a binary RPM correctly.
9) Linux version installs to /usr/local/bin, not /usr/bin
