Well, most of the new stuff works like it should be (you can even do a push-trigger -> shutters combo by checking the block -> shutters screenflag).
There is only one problem with the push infinite and trigger flags. It seems to be only working once. Say, you have 2 infinite 4-push blocks in the room, and you push one of them on a trigger, then the other one can only be moved once.
Also, this stays the rest of the game. You can't push infinite anymore when you once pushed a block onto a trigger.
