Anyone give it a whirl yet? Looks like this is the change log as of now:

In the handling of applications Added a button to manage applications.

The interface now separates the camera flash options (and camera UI was already very awesome)

In the video recording interface separated the icon to turn the LED flash.

The buttons have a new style

On display there is a new option settings Colour Profile
Settings Gallery has a new option for face recognition

The menu to display an image and has a new option “Insert face”
