As much as i understood, for you to be prepared:
S'more is no more.
Fizzy soda rework (works like any other BSODa, but splash slows down gradually.)
2 Floor is mostly same, but now it's bigger and has new notebook.
Some of floor 1 notebooks BEGONE-
Recybble is not a piece of s##t anymore i think (Pre-anger time is bigger, means it'll be longer time before he'll be up your soul. Maybe, just felt like he's got a secret rework)
Hope this helps for an unprepared player!
P.S. For Russian players: Русский сделан хреново, но минимально играемо.
