Knights of the Chalice has seen another update - after all these years, *sniff* - with a lot of bug fixes and other improvements. For example Mass Cure/Heal spells will damage undead, Discharge and Soundburst will be working on Golems and the Knights' Commander won't go on a suicide rampage during the final fight at the keep. The game also creates auto-saves before critical points of no return (Undead Tower for instance). Here's the full changelog.
