Google open sources Android 4.2

New features in Android 4.2 include increased performance for the platform’s Renderscript 3D graphics API, the ability to modify widgets so that they can be placed on a device’s lock screen, and improved internationalisation support. Some Android 4.2 devices can also drive more than one external screen and have the ability to target different content at each screen separately. Until now, Android was only able to mirror the contents of the main display on external screens.
