- Add `trip` plugin for TSP computation
- Implement raster source feature to read data (currently only .asc) from third-party sources, to be used in lua profiles.
- Instructions are now returned in match plugin (thanks to Andreas Gruß)
- Partial contraction support, new file .core
- Update to libosmium 2.3.0
- Remove protobuf dependencies (libosmium ships with an own minimal decoder)
- Parse specific restriction:* tags based on profile exceptions
- Make an exception for block barriers in bicycle and foot profile.
- Make pedestrian roads marked as destination routable with car profile.
- Make map matching more resilient against low sample rates
- Enable turn penalties on car profile, using values tuned by comparing real-world sample routes with map-matched routes.
- Add rising bollard exception to barriers for car profile.

Bug fixes:
- Fix race condition in osrm-routed
- Fix processing for data files with incorrect node references
- Fix postgis lua example
- gps_precision and matching_beta can be used as a float value
- Fix typo in foot profile that removed traffic lights
- SCC search is now run on edge-expanded graph
- Fix off-by one error in hint decoder and make padding deterministic.
