Apple just seeded the first beta of tvOS 10.2.2 to developers. This update comes one day after the launch of tvOS 10.2.1 to the public. We’re currently unsure what’s new in this version. It likely brings bug fixes and improvements.
To get this version developers will need to connect their Apple TV to a computer and manually install the IPSW via iTunes. You can download the IPSW from the developer center.
