Changes from 5.6
- Algorithm:
  - OSRM object has new option algorithm that allows the selection of a routing algorithm.
  - New experimental algorithm: Multi-Level Dijkstra with new toolchain:
    - Allows for fast metric updates in below a minute on continental sized networks (osrm-customize)
    - Plugins supported: match and route
    - Quickstart: osrm-extract data.osm.pbf, osrm-partition data.osrm, osrm-customize data.osrm, osrm-routed --algorithm=MLD data.osrm
- NodeJs Bindings
  - Merged https://github.com/Project-OSRM/node-osrm into repository. Build via cmake .. -DCMAKE_BUILD_TYPE=Release -DENABLE_NODE_BINDINGS=On -DENABLE_MASON=On.
  - OSRM object has new option algorihtm="CH","CoreCH","MLD"
- Internals
  - Shared memory notification via conditional variables on Linux or semaphore queue on OS X and Windows with a limit of 128 OSRM Engine instances
- Files
  - .osrm.datasource_index file was removed. Data is now part of .osrm.geometries.
  - .osrm.edge_lookup was removed. The option --generate-edge-lookup does nothing now.
  - osrm-contract does not depend on the .osrm.fileIndex file anymore
  - osrm-extract creates new file .osrm.cnbg and .cnbg_to_ebg
  - osrm-partition creates new file .osrm.partition and .osrm.cells
  - osrm-customize creates new file .osrm.mldgr
- Profiles
  - Added force_split_edges flag to global properties. True value guarantees that segment_function will be called for all segments, but also could double memory consumption
- Map Matching:
  - new option gaps=split|ignore to enable/disbale track splitting
  - new option tidy=true|false to simplify traces automatically
