Arasan 14.3 is available from http://www.arasanchess.org.
Changes in Arasan 14.3:
1) King safety is scaled by the opponent's material value (fixing a bug).
2) Adjustments and fixes to strength reduction feature.
3) Fix to material scoring for R vs 2 minors.
4) Do not terminate search after forced move if in analysis mode.
This is more or less the version that played in the recent WCRCC tournament. I believe it is a little stronger than 14.2b but nothing dramatic.
