iOS 11.4 will add multi-room and stereo audio to the HomePod today

The update includes AirPlay 2.

Apple will release iOS 11.4 today, which, with the inclusion of AirPlay 2, brings more functionality to the HomePod. Though other speakers, like the Amazon Echo and Google Home already feature multi-room audio, the HomePod didn't launch with that capability. It also hasn't yet supported stereo pairing. But with today's update, the HomePod now supports both features. Users can sync their HomePods with other AirPlay 2-enabled speakers and play audio throughout multiple rooms. They can also pair two HomePods to create a stereo system. HomePod will launch in Canada, France and Germany on June 18th.

Also included in iOS 11.4 is an iMessages on iCloud feature, which will give users access to all of their messages across all of their Apple devices as well as allow them to store older messages in iCloud. The feature will also apply changes across devices, so deleting a message on your iPhone, for example, will also delete it on your Mac and your iPad.
