You should be able to probe and weaponprobe (if you have the ability)
items for sale in shops now. This should be a big help to those selling
items they've crafted themselves.

Endurance and willpower should now regenerate substantially faster for
those with well-developed Fitness and Philosophy skills, respectively.
The effects of endurance and willpower regenerating artifacts and
abilities are multiplied on top of the base recuperative rate from your
skill level, so someone with high Fitness and a ring of endurance, for
example, should be seeing a dramatic difference.
