Yeah, no one really cares, but just for the sake of it being new, I played a bit of full moon Neco Arc.
-Her 5C is now double claw swipe, more range than before. Most other ground normals are the same AFAIK.
-Her j.B is the same, but her j.C is a really long reaching extendo kick.
-She still has rocket and her 623 poking thing, and keeps the same 22A/B/C.
-I did not check for 63214C or 2222C, but I assume they're both still there in full moon.
-I honestly have no idea if she has the summoning move she does in crescent, since I could not really do DP motions on stick. I did 623B once, and tried 421 but am not confident in me actually ever actually getting 421 over 214 and tk 2147.
-Her 214 is now weird. Someone posted it, 214A hides and pops up, 214B hides and pops up, but you can hold it to make her follow the opponent. Don't remember what 214C did, but it isn't an EX. The popping up makes you go up in the air, and it does damage.
-Her 236 in full moon is absolute shit. She does a really slow jump up, then lasers downwards. 236C makes her jump and do the G666 sweeping laser. It's like those auto tk flametongues but much much worse, and those auto tk flametongues are quite bad.
EDIT: Full moon Neco Arc has an airdash now. It's like Wara/Kouma/Tohno H airdashes, but goes down at a slight angle. Also it goes as far as you hold the button.
