Release notes

Overview

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

Release overview

watchOS 3.1.3 was released on January 23, 2017. Apple's consumer history characterizes it only as an improvements-and-bug-fixes update, while the dedicated advisory supplies concrete security scope.[1][2][3]

Evidence boundary

Apple does not identify individual ordinary fixes for this version, so the maintenance entry remains deliberately broad. More specific statements are limited to issues named in the security advisory.[4][3]
