This version has the following features, as well as all those from previous Android versions:

 

Lockscreen widgets - Widgets are tiny applications that can be placed on the Android homescreen and now the lock screen, which can show updated information from time to time. They also act as shortcuts to larger applications. Lockscreen widgets include Calendar, Clock, Messages, Song search and Inbox.

Photo Sphere - Take 360 degree panoramic pictures.

Gesture typing - Glide your finger over the letters you want to type rather than pressing them for faster written texts and emails.

Daydream to display - Whilst your phone's idle or docked display useful stuff like news updates, or fun stuff like your picture albums.

Multi user for tablets - Allows several users to have personal access to a device, whilst keeping their settings and content private to others.
