 ### CarPlay
 
 * Fixed an issue where an active navigation using CarPlay application with route that contains multiple legs would cause a memory leak. ([#3877](https://github.com/mapbox/mapbox-navigation-ios/pull/3877))
+* Added the `CarPlayManagerDelegate.carPlayManager(_:shouldUpdateNotificationFor:with:in:)` and `CarPlayManagerDelegate.carPlayManager(_:shouldShowNotificationFor:in:)` to provide the ability to control notifications presentation while CarPlay application is in the background. ([#3828](https://github.com/mapbox/mapbox-navigation-ios/pull/3828))
 
 ### Other Changes
 * During turn-by-turn navigation, incidents along the route are now refreshed periodically along with traffic congestion.
