Graphhopper v5.0 Release Notes

Release Date: 2022-03-23 // about 3 years ago
    • 👉 Use routing.instructions to disable instructions on the server side. datareader.instructions is used to disable the name parsing (#2537)
    • 0️⃣ no more explicit passByDefaultBarriers in FlagEncoders, blockByDefaultBarriers was renamed to just barriers, no more handling of highway=ford (#2538)
    • OSMReader no longer sets the artificial estimated_distance tag, but sets the edge_distance and point_list tags for all edges, the way_distance for selected ways and additionally the duration:seconds and speed_from_duration tags when the duration tag is present (#2528)
    • 🛠 fixed speed calculation for ferry routes with duration tags (#2528)
    • request gzipping for matrix and route clients (#2511)
    • 🛠 bugfix: client-hc now considers headings and custom models (#2009, #2535)
    • the artificial tag duration:seconds is now a long, no longer a string, commit 6d81d8ae8de52987522991edd835e42c8d2046cf
    • ➕ added FlagEncoder#getName (use just like toString() before), commit 86f6a8b5209ad8ef47c24d935f5746e7694eb11c
    • faster edge-based CH preparation, especially with large u-turn costs and GermanyCountryRule (many large weight edges due to access=destination on tracks) (#2522)
    • consider subnetworks when evaluating curbside constraints (#2502)
    • 👌 improved node-based CH performance (faster preparation and less shortcuts(=memory usage)) (#2491)
    • 🚚 the GraphHopperApplication class was moved from com.graphhopper.http to com.graphhopper.application (#2487)
    • it is now possible to add CH preparations to an existing graph folder, CH graphs no longer need to be added before GraphHopperStorage#freeze (#2481)
    • 0️⃣ the two EncodedValue implementations accept now negative values too. The default value can now only be 0 or Double.Infinity, but this option will be removed later too, see discussion in #2473
    • throw MaximumNodesExceededException instead of a generic IllegalArgumentException (#2464)
    • ✂ removed graphhopper.sh script. Use java command directly instead. (#2431)
    • ✂ removed the ferry argument of TagParser#handleWayTags. ferry ways can be recognized using the reader way (#2467)
    • ✂ removed RoadEnvironment.SHUTTLE_TRAIN. this is covered by FERRY (#2466)
    • create edge flags per edge, not per way. increases custom_area precision. areas are recognized by points along the edges now -> (#2457, #2472)
    • 🛠 fixed handling of too large mtb:scale tags (#2458)
    • ➕ added Toll.MISSING; custom models must be adapted to check for explicit toll values e.g toll != NO -> toll == HGV || toll == ALL (#2164)
    • 👉 use GraphHopper#setGraphHopperLocation before calling load() instead of GraphHopper#load(graphHopperLocation) (#2437)
    • barrier nodes at junctions are now ignored (#2433)
    • AbstractFlagEncoder#handleNodeTags was replaced by AbstractFlagEncoder#isBarrier (#2434)
    • consider heading when snapping coordinates to the road network, this is especially important for navigation (#2411)
    • OSMReader no longer sets the artificial 'estimated_center' tag and processNode also receives EMPTY_NODEs (971d686)
