Apple today released tvOS 11.3 beta 4 for testing on the fourth- and fifth-generation Apple TVs. This comes nearly two weeks after the third beta hit airwaves. To install the new build on your registered Apple TV, head over to Settings > System > Software Updates > Update Software and hit the download button. Both developers and public beta testers can expect this build this week.
There isn’t much new in this build other than bug fixes and security improvements, but we’ll, of course, let you know of any important changes spotted along the way.
