IOS 11.4 also brings Messages in iCloud to the operating system, a feature that's been in the works since iOS 11 was first introduced previous year. It did make a comeback with iOS 11.3 beta a few months later but it was pulled yet again. You can find it under Settings General Software Update.
As of the writing of this article, iOS 11.4 should be available as a free over-the-air update to all users running iOS 11. As with any iOS update, we recommend backing up your iPhone first. From there, you'll be asked to define left and right positioning, telling the app which one will be to the left and right of you. Here's a rundown of the features. Further, all your messages will appear on your new device when you sign in using the same iMessage account.
Music and video playback can now also be controlled throughout the home from the updated control center on iPhone/iPad or Apple TV. It reintroduces AirPlay 2 features, allowing audio content to be played on multiple compatible devices throughout the home. You'll also be able to take a call on your iPhone without stopping playback. This means you can play the same song everywhere or move music from one room to another using an iOS device, HomePod, Apple TV, or simply by asking Siri.

Of course, the iOS 11.4 update has a ton of other improvements, but messages in iCloud is one of the most interesting new additions. These include attachments and photos too, saving more storage space on your device. But it was quite obvious that iOS 11.4 will fix all the wrong by introducing the feature to the masses at last and Apple has delivered today.
On top of this, he says that Apple promises to ramp up its privacy focus with new features that notify users when their data is being shared with developers.
