Is there a specific topic already dedicated to this subject already, either in here or on another forum? I already tried Google-ing the subject.
Yeah, there's a thread in the tech support section.
Long story short, the Alien Hominid, Spelunky, and Meat Ninja glitches are out, the Pink Knight and Tim glitches are still in, and it's now possible to get to 310 levels completed (though it may or may not do funny things to your total time).
Also, you can redo 0.0s.
