Apple today released the third beta of an upcoming iOS 11.4.1 update for developers and tvOS 11.4.1. This comes one week after the second beta release and three weeks after the release of iOS 11.4, an update that introduced AirPlay 2 and messages in iCloud.
Registered developers can download the new iOS 11.4.1 beta from the Apple Developer Center or over-the-air once the appropriate configuration profile is installed in the Developer Center. No new features were found in the first two iOS 11.4.1 betas, indicating that Apple is focusing on bug fixes and performance enhancements in this update to fix issues that have become known since the iOS 11.4 release.
The Apple third beta of the upcoming tvOS 11.4.1 update is also available for developers to test. Apple released the second tvOS 11.4.1 beta a week ago. Three weeks ago saw the release of tvOS 11.4, an update that introduced support for AirPlay 2 on the small set-top box. The update is designed for the fourth and fifth generation of Apple TV models and can be downloaded and installed from an Apple TV profile installed with Xcode.
No new features or changes have been discovered in the first two tvOS 11.4.1 betas. The update seems to be a service release that focuses on fixing bugs discovered since the release of tvOS 11.4. The tvOS updates were of minor importance in the past, which can also be seen from the fact that there are no detailed release notes.
Of course, it should also be mentioned that the work on tvOS 11 and iOS 11 is coming to an end, as Apple plans to release iOS 12 and tvOS 12 as early as autumn.
