Angry Birds developer Rovio has just pushed out an update for the Android app and it contains a whopping 45 new levels for the game.
Of course, everyone is talking about the 45 new levels that this update brings, but it's not just bonus levels that you'll get. The update also brings fixes for some previous bugs, support for users with QVGA resolution, a NEW "boulder bird", and a little bit of a plot twist.
However, Android Police reports that one thing Rovio opted not to fix was the ability to skip to the next world even if you haven't finished all the levels in between. Instructions for that little cheat can be found here.
