Well, I haven't found anything noteworthy yet and it's been almost 2 days. I think it's safe to assume that most of the changes were just minor tweaks.
Look at
dantarion's notes, and you'll see that the exact same code is in all of these moves, and is changed everytime from "unk-F38E805D(|x|, 0x10000085)" to "unk-F38E805D(|x|, 0x10000086)". Now, I'm no coding expert or anything like that (heck, I can't even interpret this at all), but since we haven't found anything noteworthy that changed about jab,nair,bair,uair,fsmash, or dtilt, and the exact same code was found in every single one of these moves, the most likely conclusion is that there are little to no changes from the last update.
Again, call me an idiot if something IS found in the next couple of days regarding the patch, but for now, I believe that we got NO changes from the last update (as depressing as that is).
