One of the things mentioned in the new release notes is that the Elf racial enhancement line to reduce Arcane Spell Failure has been changed to (among other things) dramatically reduce the cost.

I like the change. But something got overlooked:

Drow Elves have an identical line of racial enhancements, but the Drow version never got updated. Is this an intentional snub to the Drow or did this simply get missed in the scramble for release?
