Angry Birds RIO was just updated.

The update comes with the Carnival Upheaval levels but if you bought RIO on DVD and Blu-ray, you got the Golden Beach Ball levels too. No, Angry Birds did not influence my decision to buy Rio, I did THAT on my own.

Also, for portable system users, there’s a hidden target in level 6-13 basically directly underneath the slingshot where you launch the birds. Basically, make a red bird roll underneath the ground. It will unlock the secret levels for you. but for the PC and MAC versions, you need the code with the DVD to get the Golden Beach Ball levels.

Anyway, just so those who are waiting for the update know.
