* Fixed an issue that could cause line label rendering glitches when the line geometry is projected to a point behind the plane of the camera. ([#9865](https://github.com/mapbox/mapbox-gl-native/pull/9865))
* Fixed an issue that could cause a crash when using `-[MGLMapView flyToCamera:completionHandler:]` and related methods with zoom levels at or near the maximum value. ([#9381](https://github.com/mapbox/mapbox-gl-native/pull/9381))
