Also, I know that the only things altered were this:
Up Special (Parasol)
--Many small tweaks to have up-b behave like Melee up-b.
--Air animation was missing the initial dip which made it also go too high, now matches Melee.
--Landing while raising the parasol goes into special landing (4 frames) instead of up-b landing (30 frames) which occurs while parasol is fully up. Matches Melee.
--Raising parasol hitbox comes out a frame faster 11 -> 10 to match Melee.
Others
<--Air Dodge's enabling of gravity/fastfall/mobility begins 10 frames sooner to match Melee.
but I also feel there was a slight start-up frame increase to Peach Bomber/Side B. It may just be me, though, as I use her in Every Version of Smash, and 3DS Smash has a really quick start up.
Also, Love the Pink-Gold Peach easter egg (instead of turning Metal, she turns into PG Peach from MK8)
