 ## master
 
+### Packaging
+* This library can no longer be used in applications written in pure Objective-C. If you need to use this library’s public API from Objective-C code, you will need to implement a wrapper in Swift that bridges the subset of the API you need from Swift to Objective-C. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))
+
+### User interface
+* `UserCourseView` is now a type alias of the `UIView` class and the `CourseUpdatable` protocol rather than a protocol in its own right. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))
 * Fixed an issue where user notifications displayed right turn arrows for left turn maneuvers. ([#2270](https://github.com/mapbox/mapbox-navigation-ios/pull/2270))
+* Renamed `NavigationMapView.showRoutes(_:legIndex:)` to `NavigationMapView.show(_:legIndex:)`. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))
+* Renamed `NavigationMapView.showWaypoints(_:legIndex:)` to `NavigationMapView.showWaypoints(on:legIndex:)`. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))
+* Renamed `MapboxVoiceController.play(_:)` to `MapboxVoiceController.play(instruction:data:)`. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))
+
+### Error handling
+* The `MapboxVoiceController` and `RouteVoiceController` now emit `SpeechError`s instead of an `NSError` object. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))
+* Added the `VoiceControllerDelegate.voiceController(_:didFallBackTo:becauseOf:)` method for detecting when the voice controller falls back to `AVSpeechSynthesizer`. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))
+
+### Other changes
+* Since pure Swift protocols cannot have optional methods, various delegate protocols now provide default no-op implementations for all their methods and conform to the `UnimplementedLogging` protocol, which can inform you at runtime when a delegate method is called but has not been implemented. Messages are sent through Apple Unified Logging and can be disabled globally through [Unifed Logging](https://developer.apple.com/documentation/os/logging#2878594), or by overriding the delegate function with a no-op implementation. ([#2230](https://github.com/mapbox/mapbox-navigation-ios/pull/2230))

 * You can now customize the control layer of the map template comprising of the navigation bar's leading and trailing buttons and the map buttons. ([#1962](https://github.com/mapbox/mapbox-navigation-ios/pull/1962))
 * Added new map buttons in the `CarPlayManager` and the `CarPlayMapViewController`. You can now access map buttons that perform built-in actions on the map by accessing read-only properties such as: `CarPlayManager.exitButton`, `CarPlayManager.muteButton`, `CarPlayManager.showFeedbackButton`, `CarPlayManager.overviewButton`, `CarPlayMapViewController.recenterButton`, `CarPlayMapViewController.zoomInButton`, `CarPlayMapViewController.zoomOutButton`, `CarPlayMapViewController.panningInterfaceDisplayButton(for:)`, `CarPlayMapViewController.panningInterfaceDismissalButton(for:)`. ([#1962](https://github.com/mapbox/mapbox-navigation-ios/pull/1962))

 ### Other changes
 
 * Replaced `NavigationViewController(for:styles:navigationService:viewController:)` with `NavigationViewController(for:options:)`, which accepts a `NavigationOptions` object (not to be confused with `NavigationRouteOptions`). `NavigationOptions` contains various options for customizing the user experience of a turn-by-turn navigation session, including replacing the bottom banner with a custom view controller. ([#1951](https://github.com/mapbox/mapbox-navigation-ios/pull/1951))

 * Exposes `RouteVoiceController.speak(_:)` which would allow custom subclass of MapboxVoiceController to override this method and pass a modified SpokenInstruction to our superclass implementation.
