([#7574](https://github.com/mapbox/mapbox-gl-native/pull/7574)) * Added a method to MGLMapViewDelegate, `-mapView:shouldChangeFromCamera:toCamera:`, that you can implement to restrict which parts the user can navigate to using gestures. ([#5584](https://github.com/mapbox/mapbox-gl-native/pull/5584)) * Added a `MGLDistanceFormatter` class for formatting geographic distances. ([#7888](https://github.com/mapbox/mapbox-gl-native/pull/7888)) +* Zooming by double-tap, two-finger tap, zoom buttons, shortcut keys, or demo app menu items or shortcut keys now zooms to the nearest integer zoom level.
