For some time now, the developers of #openrouteservice at HeiGIT gGmbH have been hard at work updating the core libraries of openrouteservice to use a newer version of #GraphHopper. After many long days and nights, we are finally pleased to announce the release of openrouteservice 7.0, also known as #Callisto.

As with a number of previous releases, most users will not notice large differences and changes, with most of the changes being “under the hood” and providing improvements for the routing graph building processes. As there have been so many modifications needed to the openrouteservice code alone (not to mention our forked version of GraphHopper), we have decided to released this update as a new major version.
