From now on you get 108 new puzzles every week instead of 54.
The reason is simple we now have two different worlds (plus tutorial) to choose from.

Another big change is that the game not automatically resets every week. You now have to push a button to pull the new puzzles for the new season. As long as you don't do it you have enough time to beat your current puzzles.

Aaaand I solved some bugs and maybe added some others. We'll see^^
