There is a new AI event check called New Ability which will try to detect whether you learned a new skill in the story. If it triggers, you'll get a new available ability in the ability pool. You'll get 1 point per 2 levels (starting at level 2) to spend on this pool, and each learned ability will go into your innate abilities tab.
Misc: Tweaked and marginally improved some false positives in AI event detection
