Update seems to be mostly on the gameplay related side from messing around with it myself. I didn't play last update but I assume the other characters automatically following the one you control is new. Game seems to hardlock now though under certain circumstances.
If your characters are still attacking the health container right before the transition to next stage, they'll refuse to move even after they destroyed it and your controls are locked because I'm assuming the animation where they run off-screen to the next stage isn't supposed to be interrupted.
Blue suit girl's super seems to be programmed to fire forever until it can't hit anything, but this also now hardlocks the boss if you use it on her since she won't stop firing it at her and you can't go and overdrive the boss to finish the fight.
Blue-haired girl's attack also doesn't damage the hostage container now for some reason.
