Release overview

tvOS 12.1.2 was released on January 22, 2019. Apple's consumer history describes general performance and stability improvements, while its security advisory provides the detailed technical record.[1][2]

Evidence boundary

Because Apple did not name an individual consumer feature, this article does not infer one. The structured record separates the documented maintenance statement from the documented security fixes.[3][2]
