Apple has released the first beta version of tvOS to registered developers. Targeted only at the newest version of the Apple TV, the beta can be found at Apple's tvOS Developer Resource Center.

It's not yet clear what tvOS will bring to the table when it's released to the public. The Apple TV received its first major software update just last month with tvOS 9.1, which added Siri support for Apple Music, along with compatibility with Apple's Remote application.
