Once updated, users will be able to wirelessly link two HomePod speakers to play a song in stereo, though they will also be able to play a song on HomePods in multiple rooms, or move song's playback from the kitchen to the bedroom, for example.
There are also a number of third party manufacturers on board for AirPlay 2, meaning you'll be able to use Siri to control music on speakers from some top names, including, Bang & Olufsen, Bluesound, Bose, Bowers & Wilkins, Denon, Libratone, Marantz, Marshall, Naim, Pioneer and Sonos. But iOS 11.4 sports some long-awaited features like AirPlay 2 and Messages in iCloud. The new update brings in all the features Apple had promised at last year's WWDC event, such as Messages in iCloud and AirPlay 2. It will be available for download directly from the Software Update feature of supported devices this afternoon. It also backs up iMessages so that any new device in the account can get old iMessages without restoring a backup. It backs everything up to iCloud and can free up internal storage and let you delete messages on one device and have it also be deleted on every other device.
For the HomePod, Apple is making it easy for devices to be linked.

The former spy will be the highest-ranking North Korean official to visit the U.S.in almost two decades, according to Bloomberg . Significant differences, however, remain - especially over the USA and North Korean definition of "complete denuclearization".
Apple iOS 11.4 for brings AirPlay 2 which will let users control music in their home from iOS device. In addition to using Siri or individual apps to control speaker selection and music playback, all AirPlay 2 devices available in a home will show up in iOS' Control Center. However, if you've missed it you can go to the "General" tab in the settings app and click on "Software Update". That now changes with iOS 11.4. A press release says that a two-HomePod pair will actually offer left and right stereo sound - a feature that became ambiguous during the speaker's launch period - or multi-room support.
This isn't a huge update in itself, but the inclusion of Messages on iCloud makes it a noteworthy update.
Messages: First, you should know that "Messages" also means iMessage, Apple's app that iOS device owners and Mac owners can use to send and receive texts, photos, videos, Animoji, and more. Scroll down to the list of apps with iCloud support and toggle on Messages.
