apparently there are some mistranslations in the EN notes so some stuff might be inaccurate. seems good overall; universal changes look to be more buff than nerf

nerfs
• damage from OP specials or combo starters
• pressure — looks like abare was buffed and faultless defense was definitely buffed
• guard crush

buffs
• server connection on startup 😎
• throw teching
• universal anti-air (6P)
• special inputs
• reversals
• projectiles — ky's grounded stun edge might be usable!
• fautless defense
• burst
• roman cancel
• air combos — gatlings, dash cancels, and counter hits added to some jump buttons
• counter hit combos
• combos started from RC
