Stuff you might notice even without the patch notes:

• B9 is now in an early alpha state
• Suffer folder is now locked until player has three levels unlocked in Resolve folder
• If your initial input on a hold is incorrect, then any beat-input can be held down for that hold
• --this is to prevent the player from being "punished twice" for initially missing a hold
