Just checked out the latest. Fun stuff!
It's probably only cosmetic, but the automate log seems to contain spurious entries about being "skipped since not an epub3."

Automation List Completed
With the exception of RemoveNCXGuideFromEpub3 and UpdateManifestProperties, none of my tasks should have been epub3 specific. Plus they all seemed to be successful (even if many had nothing to do). Checkpoints were created, MendPrettify was run, CSS was reformatted, etc...
