Arasan 7.4

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

Jon,
I downloaded the engine alone, and replaced 7.3 exe with the 7.4 exe. But arasanx.exe crashes as soon a move is made, either in console mode or through winboard.

I noticed this too just now. It is happening if I set log_enabled=false in arasan.rc. When log is enabled it's not crashing.

I will investigate. There is no particular reason to disable the log (it is overwritten on each invocation of the program, so it won't grow in size).

This was trivial to fix, so I did so and rebuilt the archive. If you download it again you will get the fixed version. Or you can set log_enabled=true, which is the default.
