 ### Upcoming Release
 -   Changes
     - Auth: Removed deprecated `User::UpdateEmail` method.
-    - iOS: Added an option to explicitly specify your app's `AppDelegate` class
-      name via the `FirebaseAppDelegateClassName` key in `Info.plist`. This
-      provides a more direct way for Firebase to interact with your specified
-      AppDelegate. See "Platform Notes > iOS Method Swizzling >
-      Specifying Your AppDelegate Class Directly (iOS)" for details.
