I haven't had a chance to test it out yet (probably will this weekend) but i'm guessing ThorUI users won't need an update.
From what I know so far (its very little currently) I believe the change is to the actual "create a macro" window which I didn't mod in any way.
If an update is required i'll be sure to get something nice done asap though.
I'll keep you posted via the main updater page.
