5.13.0

This release has some exciting new features: We know have relation support in the lua profiles, and support using location dependent data. In addition to that we deprecated CoreCH, since MLD is superior.

• Changes from 5.12:
  • Profile:
    • Append cardinal directions from route relations to ref fields to improve instructions; off by default see profile.cardinal_directions
    • Support of distance weight in foot and bicycle profiles
    • Support of relations processing
    • Added way:get_location_tag(key) method to get location-dependent tags https://github.com/Project-OSRM/osrm-backend/wiki/Using-location-dependent-data-in-profiles
    • Added forward_ref and backward_ref support
    • Left-side driving mode is specified by a local Boolean flag is_left_hand_driving in ExtractionWay and ExtractionTurn
    • Support literal values for maxspeeds in NO, PL and ZA
  • Infrastructure:
    • Lua 5.1 support is removed due to lack of support in sol2 https://github.com/ThePhD/sol2/issues/302
    • Fixed pkg-config version of OSRM
    • Removed .osrm.core file since CoreCH is deprecated now.
  • Tools:
    • Because of boost/program_options#32 with boost 1.65+ we needed to change the behavior of the following flags to not accept ={true|false} anymore:
      • --use-locations-cache=false becomes --disable-location-cache
      • --parse-conditional-restrictions=true becomes --parse-conditional-restrictions
      • The deprecated options --use-level-cache and --generate-edge-lookup
  • Bugfixes:
    • Fixed #4348: Some cases of sliproads pre-processing were broken
    • Fixed #4331: Correctly compute left/right modifiers of forks in case the fork is curved.
    • Fixed #4472: Correctly count the number of lanes using the delimter in turn:lanes tag.
    • Fixed #4214: Multiple runs of osrm-partition lead to crash.
    • Fixed #4348: Fix assorted problems around slip roads.
    • Fixed #4420: A bug that would result in unnecessary instructions, due to problems in suffix/prefix detection
  • Algorithm
    • Deprecate CoreCH functionality. Usage of CoreCH specific options will fall back to using CH with core_factor of 1.0
    • MLD uses a unidirectional Dijkstra for 1-to-N and N-to-1 matrices which yields speedup.
