+## 5.1.0 - TBA
+
+5.1.0 builds further on 5.0.1 and adds:
+
+* LatLngBounds includes with another bounds [#8517](https://github.com/mapbox/mapbox-gl-native/pull/8517)
+* LatLngBounds includes takes in account LatLng on the edges (cfr. core) [#8517](https://github.com/mapbox/mapbox-gl-native/pull/8517)
+* LatLngBounds facility getters/setters for LatLnbg on the edges of the bounds [#8517](https://github.com/mapbox/mapbox-gl-native/pull/8517)
+* Expose world bounds in LatLngBounds [#8517](https://github.com/mapbox/mapbox-gl-native/pull/8517)
+* OfflineRegion are validated if the bounds is found in the world bounds, else onError will be invoked [#8517](https://github.com/mapbox/mapbox-gl-native/pull/8517)
