Glad you liked it!
Left it out cuz I didn't want to list it all and it's not the draw. Since it bugged you, it might bug others, so I'll make the afterthought more inclusive.
The blast damage isn't an update, it's like that in the original version. Well, sort of—the original version had, like, a typo in it that had to be fixed by errata. So, the blast damage is like that in the errata'd version. The bonus feats are an update, but not a super meaningful one because it doesn't change the evaluation of any options in any especially notable way.
