The Nexus lineup is a synonym for extremely quick Android updates and Android 4.3 Jelly Bean is no exception.
The Nexus 4, Nexus 7, Nexus 10 and even last year's Samsung Galaxy Nexus will start getting the update to Android 4.3 today.

Android 4.3 is a gradual update that brings stability improvements and some neat developer features. Right below is a summary of its new features.
