+### iOS EdgeIdentity 5.1.0
+
+* Added support for processing `updateProfileAttributes` events dispatched by AEPCore. When `MobileCore.updateProfileAttributes(ProfileAttributes(timeZone: TimeZone(identifier: "America/New_York")))` is called, EdgeIdentity validates the IANA timezone identifier, deduplicates against persistent storage (retained across app restarts), and forwards changed values to the Adobe Edge Network as a `profile.updateAttributes` XDM event.

+## updateProfileAttributes
+
+Updates profile attributes for syncing to the Adobe Experience Platform Edge Network.
+
+<InlineAlert variant="info" slots="text"/>
+
+It is the responsibility of the app to provide valid and up-to-date profile attribute values. The SDK does not read these values automatically from the OS. Call this API as early as possible during app launch so that the Edge Network has accurate data before personalization or notification requests are made.

+<InlineAlert variant="info" slots="text"/>
+
+Requires the [Identity for Edge Network](../../../edge/identity-for-edge-network/index.md) extension to be registered.
