Apple on Tuesday seeded the sixth beta of tvOS 11.3 to developers. The move follows beta 6 releases of iOS 11.3, watchOS 4.3 and macOS High Sierra 10.13.4, and the update can be installed on fourth and fifth generation Apple TVs with the appropriate profiles.

tvOS 11.3 doesn’t include a lot of user-facing changes, but it does bring about Match Content support, automatic frame rate switching to 4th gen Apple TVs, and automatic AirPlay switching. Early betas did include support for AirPlay 2, but that has since been pulled.

Given the amount of betas we’ve seen with tvOS 11.3 and Apple’s other platform updates, we’re expecting to see public releases sometime soon. Last week the company announced an event scheduled for March 27, so it’s possible this is a target launch window for them.
