Here are the highlights for GraphHopper 0.8:

• the new map matching algorithm based on hidden markov chains is finally integrated and gives us a big quality improvement, thanks to @michaz (GraphHopper) and @stefanholder (BMW Car IT). This feature was already deployed 2 months ago in our GraphHopper Directions API. Some improvements were done by @kodonnell.
• the osm import module is split from the core #450 making Android and iOS integration cleaner
• there is a new overlay module #781 allowing you to specify GeoJSON at import time to change properties like access and speed of the routing graph
• new ‘more standard’ code formatting for all repositories #770
• many UI fixes like upgrading to leaflet 1.0, thanks to @fbonzon (Bikewithme)
• updated the iOS port, thanks to Calin @clns
• travis build enhancements like running against jdk9 and deploying snapshots #806, thanks to @mprins
• a new ‘on-demand’ weighting with a new data encoder #730
• elevation interpolation in tunnels&bridges #713, thanks to @highsource (DB Systel)
• fixing time calculation for turn costs #393
• a new short_fastest weighting #747
• Several updates to Android build/sample from @devemux86 (talent)
• several bug fixes (incl. three major)

The changelog is here – please read about the necessary changes to your config.properties and/or your Java code. Dowload the new version here. As the documentation has slightly improved we’d like your input here as well.

In the next release we expect bigger changes to come like one top secret 😉 and this exciting work from @devemux86 which continues the work from VTM (OpenScienceMap) and has OpenGL support, allows map rotation, iOS support and more, while keeping compatibility with the Mapsforge file format.

And if you like OpenStreetMap as we do, consider supporting them via money.

Happy routing!
