+# 5.16.0
+  - Changes from 5.15.2:
     - Guidance
       - ADDED #4676: Support for maneuver override relation, allowing data-driven overrides for turn-by-turn instructions [#4676](https://github.com/Project-OSRM/osrm-backend/pull/4676)
       - CHANGED #4830: Announce reference change if names are empty
       - CHANGED #4835: MAXIMAL_ALLOWED_SEPARATION_WIDTH increased to 12 meters
       - CHANGED #4842: Lower priority links from a motorway now are used as motorway links [#4842](https://github.com/Project-OSRM/osrm-backend/pull/4842)
