The version history of the Android mobile operating system began with the release of the Android beta in November 2007. The first commercial version, Android 1.0, was released in September 2008. Android is under ongoing development by Google and the Open Handset Alliance, and has seen a number of updates to its base operating system since its original release. These updates typically fix bugs and add new features. Since April 2009, Android versions have been developed under a codename and released in alphabetical order: Cupcake, Donut, Éclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, and Jelly Bean. As of 2012, over 400 million active devices use the Android OS worldwide.[1] The most recent major Android update was Jelly Bean v4.1, which was announced in June 2012, and released into the Android Open Source Project a month later.
