Overview

Editorial synthesis with inline references and a source ledger when citations are available.

Release overview

watchOS 4.2.2 was released on January 23, 2018 as a maintenance update with a version-specific security repair set.[1][2]

Evidence boundary

Apple's consumer note gives no named feature or individual ordinary fix beyond improvements and bug fixes. The page therefore keeps maintenance generic and uses the security advisory for concrete technical scope.[3][2]
