Update August 1th
So, what's new?
Lava levels (like seen in Rovio's facebook teaser). Seem to be only the newest levels (1300+). I'm stuck at level 720, so it will take a while for me to play them.
Three new hats: Birthday hats (2x), Chief hats (3x) and Icecream hats (4x).
The Clan system where you choose a clan (with name and country) up to 50 members. You play a 5-stage match and win one point. 2nd match costs 20 gems, you win 2 points. 3rd match costs 60 gems, you win 3 points, and so on. The first three in the clan ranking get a small Black pearl bonus. Every 15 points you make, you get a little goodie like feathers or gems.
After installing the update, my star ranking decreased from 122 to now 119. What the heck?
