 * Merge instructions now indicate whether to merge to the left or the right, as when navigating online. ([valhalla/valhalla#1892](https://github.com/valhalla/valhalla/pull/1892), [valhalla/valhalla#1989](https://github.com/valhalla/valhalla/pull/1989))
 * Fixed an issue where spoken and visual instructions sometimes omitted the cardinal direction after a route number in the United States. ([valhalla/valhalla#1917](https://github.com/valhalla/valhalla/pull/1917))
 * A spoken instruction about an exit ramp no longer specifies the side of the road if the ramp branches off the slow lane (on the right side in regions that drive on the right). ([valhalla/valhalla#1990](https://github.com/valhalla/valhalla/pull/1990))
+* Removed `NavigationMapViewDelegate.navigationMapView(_:routeStyleLayerWithIdentifier:source:)`, `NavigationMapViewDelegate.navigationMapView(_:routeCasingStyleLayerWithIdentifier:source:)` in favor of four new delegate methods to customize the route styling ([#2377](https://github.com/mapbox/mapbox-navigation-ios/pull/2377)):
+  * `NavigationMapViewDelegate.navigationMapView(_:mainRouteStyleLayerWithIdentifier:source:)` to style the main route.
+  * `NavigationMapViewDelegate.navigationMapView(_:mainRouteCasingStyleLayerWithIdentifier:source:)` to style the casing of the main route.
+  * `NavigationMapViewDelegate.navigationMapView(_:alternativeRouteStyleLayerWithIdentifier:source:)` to style alternative routes.
+  * `NavigationMapViewDelegate.navigationMapView(_:alternativeRouteCasingStyleLayerWithIdentifier:source:)` to style the casing of alternative routes.
+* Added the ability for the route line to disappear as the puck travels along a route during turn-by-turn navigation. ([#2377](https://github.com/mapbox/mapbox-navigation-ios/pull/2377))
+* Fixed an issue where the casing for the main route would not overlap alternative routes. ([#2377](https://github.com/mapbox/mapbox-navigation-ios/pull/2377))
