To give you some info about what you asked though.
Nu has two modes: Dia and Luna. Luna mode has that halo thing above her head
The Act Parser 66/44 cancels are only available in Dia mode from D moves and 6C (also possible in the air)
Luna mode has the 236D oki still, though it has less hits. Dia mode 236D is like CT Nu's except it knocks back full screen similar to Lambda's 236B
Dia's drives are projectile level 1. Luna's drives are projectile level 2.
Dia's gravity has no hitbox and takes 30% of the gravity guage. Luna's gravity has a hitbox and ground bounces on air hit (it forces crouching on ground hit) and takes 70% of the gravity gauge on whiff.
Seems that way. No one ever mentioned anything about it besides its new input.
