       - CHANGED #4830: Announce reference change if names are empty
+      - CHANGED #4835: MAXIMAL_ALLOWED_SEPARATION_WIDTH increased to 12 meters
     - Profile:
       - FIXED: `highway=service` will now be used for restricted access, `access=private` is still disabled for snapping.
       - ADDED #4775: Exposes more information to the turn function, now being able to set turn weights with highway and access information of the turn as well as other roads at the intersection [#4775](https://github.com/Project-OSRM/osrm-backend/issues/4775)
