Mii Gunner's Absorbing Vortex (Down B 3) had its endlag significantly reduced.
Moves with reduced endlag that aren't mentioned in the OP are Link's Fthrow, Diddy's grabs [editor's note: pretty sure Zapp meant increased endlag here], Samus' grab (unknown if it's just standing or all grabs), Duck Hunt's Nair landing lag, Game & Watch's Bair landing lag, Charizard's Dthrow, Villager's Dthrow, Villager's grab (unknown if it's just standing or all grabs), Mii Swordsman's jab, ftilt, dash attack, Dsmash, and Fair landing lag, and there's some sort of change to Pac Man's Side B that I can't quantify yet.
