Release notes

Overview

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

Release overview

watchOS 8.4 was released on January 26, 2022. Apple's consumer note identifies a fix for some chargers that did not work as expected, while the accompanying advisory documents security work across ColorSync, Crash Reporter, iCloud, the kernel, WebKit, and WebKit Storage.[1][2]

Source boundary

Apple did not publish a broader version-specific feature list for this maintenance release. This record therefore stays with the charger fix and the named security surfaces, and makes no undocumented-change or beta-stage claims.[3][2]
