None at all. If you see this and this, you'll see that they are exactly the same list and order of TMs.
Rock Smash was turned into an HM, and it's TM status was replaced by Secret Power. Other than these there are no exceptions.
Hope I helped!
Rock Smash and Dive returned as HMs, but apart from them nothing has changed from looking through Serebii's TM/HMS lists.
Hope I helped. :)
