We brought you news this was incoming, and it's now been released as Sonos makes the Sonos Software 3.1 available to all Sonos users globally.

The free one-button update integrates Twitter into the Sonos Controller interface, which means Sonos users can send the name and artist of the track playing to their friends and followers.

The Twitter functionality is available on the Sonos Controller for iPhone, the Sonos Controller 200 and the Sonos Controller for Mac or PC.

Other features of Sonos Software 3.1 include full support for the new ZonePlayer S5 which means it will work "seamlessly" with all previous products.

Sonos says the Controller for iPhone 3.1 is currently awaiting approval from Apple.
