Release notes

Overview

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

Release overview

watchOS 5.0 launched on September 17, 2018 with Activity competitions, automatic workout detection, new workout and running tools, Podcasts, Walkie-Talkie, new faces, a more capable Siri face, notification controls, health alerts, system utilities, and security repairs.[1][2][3]

Evidence boundary

Apple limited watchOS 5 to Series 1 and later and noted regional variation. The consumer history separates 5.0.1 and later updates, so their fixes are not included in the 5.0 launch record.[4][5]
