9.0 [not yet released]

  • max_slope is now a signed decimal, see #2955
  • move sac_scale handling out of foot_access parser and made foot safer via lowering to sac_scale<2, same for hike sac_scale<5
  • removed shortest+fastest weightings, #2938
  • u_turn_costs information is no longer stored in profile. Use the TurnCostsConfig instead
  • the custom models do no longer include the speed, access and priority encoded values only implicitly, see docs/migration/config-migration-08-09.md
  • conditional access restriction tags are no longer considered from vehicle tag parsers and instead a car_temporal_access encoded value (similarly for bike + foot) can be used in a custom model. This fixes #2477. More details are accessible via path details named according to the OSM tags e.g. for access:conditional it is "access_conditional" (i.e. converted from OSM access:conditional). See #2863 and #2965.
  • replaced (Vehicle)EncodedValueFactory and (Vehicle)TagParserFactory with ImportRegistry, #2935
  • encoded values used in custom models are added automatically, no need to add them to graph.encoded_values anymore, #2935
  • removed the ability to sort the graph (graph.do_sort) due to incomplete support, #2919
  • minor changes for import hooks, #2917
  • removed wheelchair vehicle and related parsers, with currently no complete replacement as it needs to be redone properly with a custom model
  • removed deprecated PMap.put

8.0 [18 Oct 2023]

  • access "turn"-EncodedValue of EncodingManager through separate methods, see #2884
  • removed fastest weighting for public usage, use custom instead, see #2866
  • removed shortest weighting for public usage, use a high distance_influence instead, see #2865
  • removed duration:seconds as intermediate tag
  • /info endpoint does no longer return the vehicle used per profile and won't return encoded value of vehicles like car_average_speed
  • Country rules no longer contain maxspeed handling, enable a much better alternative via max_speed_calculator.enabled: true. On the client side use max_speed_estimated to determine if max_speed is from OSM or an estimation. See #2810
  • bike routing better avoids dangerous roads, see #2796 and #2802
  • routing requests can be configured to timeout after some time, see #2795
  • custom_model_file string changed to custom_model_files array, see #2787
  • renamed EdgeKVStorage to KVStorage as it is (temporarily) used for node tage too, see #2705
  • bike vehicles are now allowed to go in reverse direction of oneways, see custom_models/bike.json #196
  • prefer cycleways, bicycle_road and cyclestreet for bike routing, see #2784 and #2778
  • add support for further surfaces like pebblestones or concrete:lanes, see #2751
  • reduced memory usage for urban density calculation, see #2828
  • urban density is now based on road junctions, so the according parameters need adjustment in case the config file does not use the defaults, see #2842
  • removed heading penalty time, see #2563
  • base graph no longer allows loop edges, see #2862

7.0 [14 Mar 2023]

  • remove StringEncodedValue support from custom model due to insufficient usage/testing
  • handle also node_tags in handleWayTags, when extending AbstractAccessParser call handleNodeTags, #2738
  • Format of 'areas' in CustomModel changed to 'FeatureCollection'. The old format is deprecated and will be removed in a later version, #2734
  • TagParser#handleWayTags no longer returns an IntsRef. We assume it never returned anything other than the input IntsRef.
  • there is no longer a default value for the distanceInfluence parameter in custom models sent via client-hc. Previously it was 70. Not setting it explicitly now means the server-side value will be used. getDistanceInfluence can now be null. Server-side profiles with custom weighting now use distance_influence: 0 by default (previously it was 70). see #2716
  • there is a new, required 'import.osm.ignored_highways' configuration option that must be used to not increase the graph size and decrease performance for motorized-only routing compared to previous versions, #2702
  • new osm_way_id encoded value, #2701
  • the parameters vehicle, weighting, edge_based and turn_costs are no longer supported, use the profile parameter instead
  • removed motorroad to road_class conversion, #2329

  • internal keys for EdgeKVStorage changed to contain the street_ prefix like the path details too. Similarly, the extra_info in the instructions of the API response, see #2661
  • subnetwork preparation can now be run in parallel to slightly speed up the base graph import (#2737)
  • The block_area parameter was removed. Use custom model areas instead.

  • backward incompatible change as instructions and the street_name path detail do no longer contain the ref #2598
  • StringIndex is now EdgeKVStorage and can store e.g. byte arrays. String values needs to be limited to 255 bytes before storing them. See EdgeKVStorage.cutString and #2597.
  • the Matrix client changed and users have to adapt the usage, see #2587

  • no cachedWays and cachedPoints in Path anymore
  • Path.findInstruction was moved to InstructionList.find
  • if start and end point are identical an algorithm will find the path consisting only of one node, one point and one instruction (finish instruction), but without edges

  • important graph incompatibility as properties cannot be loaded. renamed osmreader.bytesForFlags to graph.bytesForFlags, renamed config property osmreader.acceptWay to graph.flagEncoders
  • default weighting is now fastest, fixing #261

  • EncodingManager cannot be null in GraphHopperStorage. If you need to parse EncodingManager configuration from existing graph use EncodingManager.create
  • no reflection done in EncodingManager which improves portability and makes configuration of encoders possible before adding to manager
  • removed dijkstraNativebi as no performance advantage but maintenance disadvantage and similar to oneToManyDijkstra
  • to provide context for turn costs we needed to add prevEdgeId into Weighting.calcWeight, see new documentation
  • with the introduction of lock protection mechanism (see #112) GraphHopper needs always write access, see also #217
  • new GraphHopper.clean method to remove the graph directory via Java API

0.3.0 [13 May 2014]

  • introduced prefer bits, now bike uses more bits and 3 bike encoder do not fit into 32 bit anymore, will be fixed later
  • moved Translation argument into Path.calcInstruction for more fine grained control, instructions are now uncached and GHRequest: new locale parameter
  • CoordTrig and the like are removed, GHPlace is mostly replaced by GHPoint and so GHRequest has now methods ala addPoint instead
  • removed isBoth from AbstractFlagEncoder, moved canBeOverwritten and associated test to PrepareEncoder
  • removed unused directory.rename
  • refactor edge.copyProperties into copyPropertiesTo to have similar semantics as Graph.copyTo
  • calcWeight now contains reverse boolean to calculate correct direction dependent weight
  • completely different web API response format. see docs/web
  • swapDirections is renamed to reverseFlags (EncodingManager and FlagEncoders)
  • edgeState.detach has now a reverse parameter, just use false to get previous results
  • web api: buildDate contains now timezone, algoType is replaced with weighting
  • dijkstraNative is now dijkstraNativebi
  • fixed #151
  • calcWeight now contains reverse boolean to calculate correct direction dependent weight
  • EncodingManager always takes the encoders in constructor, to force always init
  • GraphHopper.setMemory(true, true/false) was refactored to GraphHopper.setMemory(true/false), use mmap config via GraphHopper.setMemoryMapped()
  • incompatible edges => you need to re-import data and/or update the edges file
  • the instructions of the web response does not contain times (string) but instead millis (long)
  • PrepareContractionHierarchies.setPeriodicUpdates is now in percentage not in absolute counts
  • improved bike routing #132, #138, #139, #150
  • gpx export via API, HTTP (route?type=gpx) and web interface is possible: #113, #136, #141

0.2.0 [23 Nov 2013]

  • change inconsistent default settings for contraction hierarchies in the API - see https://lists.openstreetmap.org/pipermail/graphhopper/2013-December/000585.html
  • fixed issues with android:
    • graphhopper: use maps from 0.2 path; updated maps
    • mapsforge: use mapsforge-map dependency; merged #461; avoid duplicates otherwise mapsforge-core would be duplicate ( ?)
  • refactored/renamed classes and methods:
    • refactor 'flags' from int to long (still only int is stored)
    • replacing Graph.edge(a,b,dist,edgeFlags) by Graph.edge(a,b).setDistance().setFlags()
    • FlagEncoder.flags => use FlagEncoder.setProperties or separate setAccess and setSpeed method
    • renamed LocationIDResult to QueryResult and Location2NodesNtree to LocationIndexTree
    • renamed Location2IDIndex to LocationIndex
    • renamed WeightCalculation to Weighting and getWeight to calcWeight, the URL parameter algoType in web module is now deprecated and 'weighting' should be used
    • removed GHDijkstraHeap, GHDijkstraHeap2
    • made DistanceCalc into interface (new DistanceCalcEarth implementation)
    • made GraphStorage into interface (new GraphHopperStorage implementation) move some methods from Graph into GraphStorage -> optimize + node removal stuff -> not necessary in algorithms
  • incompatible storage layout due to: pluggable endianness (#103) -> changed default endianness to LITTLE
  • add highly experimental UnsafeDataAccess to speed up search ~15%
  • several small bug fixes and improvements
  • different edge insert
  • important bug fix for edge retrieval which leads to massive speed up in prepare + CH algos
  • finally fixed major feature request #27 to allow gps-to-gps queries instead of only junction-to-junction ones.
    • follow up in #52 and #115
    • slower but more precise and necessary edge distance calculation
  • fixed bug #105 for disconnected areas
  • fix which made CH preparation ~5% faster
  • more align API for all algorithms. and initCollection is called via 1000 not something depending on the graph size
  • API changed
    • case of vehicle now case does not matter
    • returned distance is in meter now
  • better i18n support
  • fixed major bug #102 when removing subnetworks
  • fixed bug #89 for trams on roads
  • completed improvement #93 for ferries
  • edge explorer makes none-CH algorithms ~8% faster
  • link to all closed issues: https://github.com/graphhopper/graphhopper/issues?milestone=2&state=closed

0.1.1 [06 August 2013]

  • correct maven bundling and some more issues
  • more i18n

0.1 [23 July 2013]

  • initial version with lots of features
  • 24 closed issues: https://github.com/graphhopper/graphhopper/issues?milestone=3&state=closed, e.g.:
    • Route instructions
    • Implement OSM import for bike/foot/car
    • More compact graph (nodes along a way are stored in a separate storage => faster and reduced RAM usage)
    • Made routing working world wide. Make German-sized networks working on Android.
    • Made routing faster via bidirectional algorithms, contraction hierarchies, graph sorting, better OSM integration and some fine tuning.
