Overview

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

Release overview

watchOS 8.6 was released on May 16, 2022. The consumer-facing additions were regional: Apple enabled the ECG app on supported Apple Watch models in Mexico and made irregular-rhythm notifications available there.[1][2]

Security and source boundary

The security advisory covers AppleAVD, DriverKit, ImageIO, the kernel, signature validation, WebKit, and other components; Apple said one AppleAVD issue may have been actively exploited. No broader version-specific feature list is documented, so this entry stays within those regional and security claims.[3][2]
