What are the differences between DC Adventures and 3e M&M?

DC Adventures is a version of 3e Mutants & Masterminds, released in advance of the core 3e books. In the course of answering someone’s question on the Ronin Army forums about the legality of the Green Lantern build, I cited the different rule for Create, namely that ranged attacks were done as Ranged Damage with an allowable trade-off, versus standard 3e where they are treated as an Area Attack and thus are strictly PL capped.

That made me realize that I wasn’t certain if I knew all of the differences between the two versions, aside from a different setting.
