Apple blog Mac4Ever shared the release notes in French, which we've translated and embedded below in English.
While there aren't too many surprises, it's worth noting that Messages on iCloud is not listed, despite being enabled in the latest iOS 11.3 and macOS 10.13.4 betas. Apple did say the feature is included in the betas "for testing and evaluation purposes," so it was never entirely clear if it would be ready for the final release.
AirPlay 2 is also not listed, although the protocol was removed from the later beta versions of iOS 11.3 and tvOS 11.3. Messages on iCloud and AirPlay 2 were also not listed in macOS 10.13.4 release notes leaked last week.
Beyond that, the release notes seemingly confirm Apple's new Battery Health feature on iPhones will still be considered a beta feature in the iOS 11.3 public release, Advanced Mobile Location support where available, App Store review sorting, and improved charging management for always-plugged-in iPads.
As expected, there are also new accessibility features, a wide range of stability improvements and bug fixes, and other enhancements:
- ARKit 1.5 allows developers to place virtual objects on vertical surfaces like walls and doors in addition to horizontal surfaces
- Adds support for detecting and incorporating images like movie posters or artwork into AR experiences
- Supports a higher resolution real-world camera view when using AR experiences
iPhone Battery Health (Beta)
- Displays information on iPhone maximum battery capacity and peak performance capability
- Indicates if the performance management feature that dynamically manages maximum performance to prevent unexpected shutdowns is on and includes the option to disable it
- Recommends if a battery needs to be replaced
