+- document which values of OSM tag `surface` are considered for way surface categories ([#1794](https://github.com/GIScience/openrouteservice/pull/1794))
+- config parameter `maximum_locations` to snapping endpoint ([#1796](https://github.com/GIScience/openrouteservice/pull/1796))
 ### Changed
-- way surface is now being determined based only on the value of OSM `surface` tag; when the tag is not present the surface is reported as "Unknown" and is no longer being inferred from the way type ([#1794](https://github.com/GIScience/openrouteservice/pull/1794))
