Apple started distributing a new version of its mobile operating system - iOS 11.4. The update will become available to everyone in the near future.One of the most pleasant features that the update will bring will be the ability to store messages from iMessages in iCloud. This will not only help to synchronize the correspondence between all your devices, but also to save their internal memory. Recall that this feature has been previously seen in the test version of the operating system, but the final iOS 11.3 has not been included. Another long-awaited innovation - support for AirPlay 2. This will allow you to create a multi-room audio system to transmit music from anywhere in the house to devices working in sync. To do this, you can manually select a list of devices on which to play music, or ask Siri for help. The update to iOS 11.4 has already started rolling out to compatible iPhone, iPad and iPod touch devices. You can get it over the air or through iTunes.
