Following the releases of the first builds of iOS 9.3.2, watchOS 2.2.1, and OS X 10.11.5, Apple has also seeded developers with the first beta of tvOS 9.2.1. The update’s available from the developer center and carries the build number of 13Y5742b.
There doesn’t seem to be any new user facing changes in the latest build for the OS of the Apple TV, as dot-dot updates tend to focus on bug fixes and general performance enhancements. In fact, much like the OS X 10.11.5 beta, there doesn’t seem to be any release notes for tvOS 9.2.1 either, so as of now, we’re playing this one by ear.
We’ll update this post if anything new or interesting is found in the latest build!
