Release overview

tvOS 9.2.1 was released on May 16, 2016. Apple's retained first-party record supports the date and a detailed security repair set, but no consumer feature or ordinary-fix inventory.[1][2]

Evidence boundary

Because Apple's current consumer-update history does not retain tvOS 9.2.1 notes, this page avoids assigning a broad bug-fix label or any specific user-facing behavior that the first-party archive does not support.[1][2]
