After six betas, iOS 11.4 was officially released to everyone with a compatible iPad, iPhone, and iPod touch. Some features are ones that Apple promised over eight months ago when iOS 11 was first pushed out. This update makes sense since iOS 12 will be announced at WWDC on June 4, and you can't announce a new version like that without first delivering on promises made for the one before it.
The iOS 11.4 update on May 29 is more of a stability update than the feature-filled iOS 11.3, but it's far from an empty release. New features in the stable iOS 11.4 update include AirPlay 2 support, Messages in iCloud, USB Restricted Mode, and a new wallpaper, to name the big ones. There's even a fix for the nasty 3D Touch issue that was plaguing iPhone users since iOS 11.3.
You can download the new update right now by going to Settings –> General –> Software Update. Once you see the new update, you can follow the on-screen instructions to download and install iOS 11.4.
Messages in iCloud (previously called "Messages on iCloud"), which we hoped would appear in the first iOS 11 release, provides effortless Messages syncing between iOS and Mac devices, as long as your Mac is running macOS 10.13.5 or higher, which is expected to drop shortly.
AirPlay 2, which allows users to control multiple speakers in their home using Control Center, HomeKit, and Siri. You can start playback from one room to another, transfer audio from one room to another, play music on all speakers throughout your house at once, and even turn your two HomePods into a stereo set of speakers.
While beta testers have had their hands on the features for quite some time now, it wasn't certain whether Messages in iCloud and AirPlay 2 would make it to iOS 11.4's official release. Apple led us to believe we'd see their launches with iOS 11.3, as the features were included in that version's beta run. Nevertheless, 11.3 came and went without these features, with Apple opting instead to continue their beta trials with 11.4.
Aside from those two big updates, other new features in iOS 11.4 includes a new wallpaper for iPhone 8 and 8 Plus models, which was previously only available on the PRODUCT(RED) iPhone 8 and 8 Plus, a fix for the dreaded 11.3 3D Touch bug, and ClassKit support for educational purposes (school iPads only).
For the security-minded Apple fans, iOS 11.4 introduces a new feature that is sure to be of interest. After seven days of remaining locked, your iPhone will restrict its Lightning port to charging mode only. If an intruder tries to use a USB iPhone-cracking tool such as Grayshift or Cellebrite after this period, their efforts will fail.
Below, you'll find the complete release notes from Apple for iOS 11.4.
