This change includes some extensive rewriting of the shared underlying functions as well as the cosmetic changes. Rope destruction should happen instantly down its entire length now. Rope boxes themselves are now "climbable", making it easier to transfer from one rope to another. There's also a new user setting for limiting the number of rope box types available to the player.
