What is the roadmap for iOS 10 Notification features (i.e. rich notification such as UNNotificationContent)?

UILocalNotification is deprecated in iOS 10.

LocalNotification is still working in my project. However, I would like to incorporate some of the new notification features into my game. Specifically, pulling down the banner notification will have additional buttons appear.

 if (UnityEngine.iOS.NotificationServices.enabledNotificationTypes ==    UnityEngine.iOS.NotificationType.None)  {
         UnityEngine.iOS.NotificationServices.RegisterForNotifications (
             UnityEngine.iOS.NotificationType.Alert|
             UnityEngine.iOS.NotificationType.Badge|
             UnityEngine.iOS.NotificationType.Sound);
     }
     UnityEngine.iOS.NotificationServices.ClearLocalNotifications ();
     UnityEngine.iOS.LocalNotification notif = new UnityEngine.iOS.LocalNotification ();
     notif.fireDate = DateTime.Now.AddSeconds (10);
     notif.alertBody = "Hello!";
     notif.hasAction = true;
     notif.alertAction = "Alert";
     UnityEngine.iOS.NotificationServices.ScheduleLocalNotification (notify);

My sample code above is able to display a notification on iPhone devices (tested on iOS 9 and iOS 10). However, notif.hasAction and notify.alertAction has no effect on the iOS 10 device's notification.

Need help please. Thank you.
