As another Apple event is right around the corner, Apple is gearing up its latest software updates that are expected to launch at the same time. Today, they seeded the sixth iteration of their tvOS 9.2 beta to developers.
The new beta comes separately from the other beta 6 iterations in the current cycle, including iOS 9.3, OS X 10.11.4 El Capitan, and watchOS 2.2, which were launched three days ago. Normally, for each iteration, there is an Xcode release to coincide with it; however, Xcode 7.3 is still on beta 5.
According to the release notes, tvOS 9.2 beta 6 only includes bug fixes and general improvements, as did beta 5.
