A couple of weeks ago, Apple seeded developers with the fourth build of tvOS 10.2.2 for testing on the fourth-generation Apple TV. Now, the fifth build is rolling out to the same party for the same purpose.
If your set-top-box is registered for preview builds of the OS, head over to Settings > System > Software Updates > Update Software and hit the download button.
So far, we’ve only been able to spot bug fixes and security enhancements in this build of tvOS 10.2.2. That said, if you spot something worth mentioning, you can tip us at firstname.lastname@example.org and @MBEDDEDMaximum on Twitter.
