Release notes

What changed

Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.

Release candidate documentation

Apple's canonical developer page identifies itself as watchOS 26.6 RC Release Notes. This article attaches only the changes enumerated on that RC-labeled page to the existing RC route.[1]

Documented RC delta

The canonical developer note still identifies itself as watchOS 26.6 RC Release Notes and limits the structured inventory here to HealthKit authorization and temporally weighted statistics plus StoreKit test-session connectivity in Simulator. Each occurrence below comes from an item Apple places on that RC page.[1]

Evidence boundary

No cumulative public support note, public security advisory, earlier beta snapshot, undocumented behavior, build number, release date, or cross-platform assumption is projected onto this event. The current RC-titled developer note supports the enumerated changes, but it does not provide durable historical artifact metadata.[1]
