I just went into the Davon's Watch bank, and it was changed. Now it's called the Hlaalu Treasury and the guy no longer gets angry when you step behind the counter.
The Argonian was also moved.
Also the explanation about crafting received additional voices.
The Wood elf in Mournhold no longer changes her voice when you ask her about clothing.
Did you notice any other such undocumented changes?
(Actually I'm not even sure if it was documented, I didn't notice it that's for sure)
