Apple today seeded a revised version of the second tvOS 11 beta to developers for testing. The new version has a build number of 15J5310h, compared to 15J5310e for the original version of second beta, which was released last Wednesday.
It's unclear what changes have been made in the revised version, but this article will be updated if any differences are discovered.
Registered developers can download tvOS 11 by connecting the Apple TV to a computer with a USB-C cable and installing the beta software using iTunes.
tvOS 11 received little attention at the Worldwide Developers Conference, but according to the release notes, it introduces a few new features to the operating system.
tvOS 11 brings automatic switching between light and dark mode based on local time, Home screen syncing options that keep multiple Apple TVs in a household in sync, new background modes and notification support, Focus API improvements, custom sound support, network-based pairing and development support, and improvements to Mobile Device Management.
Later this year, Apple will partner with Amazon to bring an Amazon Prime Video app to the Apple TV for the first time, and in tvOS 11, AirPods are able to pair automatically with an Apple TV.
The new tvOS 11 update is only available for registered developers at the current point in time, but Apple plans to release a public tvOS 11 beta in the future.
