The update to iOS 11.4 brings with it a few notable new features.
Messages in iCloud is coming with iOS 11.4 as well.
The new version of iOS includes AirPlay 2 multi-room audio, support for HomePod stereo pairs, and Messages in iCloud. The new version - which is arriving on iPhone, iPad, and the HomePod - was announced earlier today, with its support for bringing some much-needed features to Apple's smart speaker.
However, you can check if the update is available for you by heading into the Settings menu, tapping General and then selecting Software Update. As with any iOS update, we recommend backing up your iPhone first. Further, AirPlay 2 is set to add multi-room audio support to iOS devices, the HomePod, Apple TV and compatible third-party speakers that support Apple's wireless audio protocol.
TvOS 11.4 and watchOS 4.3.1 don't contain almost as many exciting new features as iOS 11.4, but if you like playing music from your Apple TV you should definitely grab the update ASAP. The biggest updates here are, unsurprisingly, on the streaming media front, including the arrival of AirPlay 2, and the long awaited ability to pair up two HomePods for some stereo music living room listening.
If a user deletes a message on one device, that message will be wiped from all devices instantly.
IOS 11.4 is now available to download. That now changes with iOS 11.4. With the feature, all your iMessages are stored in iCloud. 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 Mac, go to Preferences within the Messages app and click the checkbox next to Enable Messages in iCloud.
