Feats have become talents

Feats were retired in version 0.20. Their place is taken by talent trees, which change how a class's skills play.

What changed

Ability Score Improvements stay (levels 4, 8, 12, 16, 19 for most classes): +2 to one score or +1 to two, applied for you to your class's suggested spread until you change it.
Every feat a hero took was turned into 2 spare ability points, so nothing was lost.
In their place you earn a talent point every level, 24 by level 20.
