- Changes from 5.9:
    - Profiles:
      - New version 2 profile API which cleans up a number of things and makes it easier to for profiles to include each other. Profiles using the old version 0 and 1 APIs are still supported.
      - New required `setup()` function that must return a configuration hash. Storing configuration in globals is deprecated.
      - Passes the config hash returned in `setup()` as an argument to `process_node/way/segment/turn`.
      - Properties are now set in `.properties` in the config hash returend by setup().
      - initialize raster sources in `setup()` instead of in a separate callback.
      - Renames the `sources` helper to `raster`.
      - Renames `way_functions` to `process_way` (same for node, segment and turn).
      - Removes `get_restrictions()`. Instead set `.restrictions` in the config hash in `setup()`.
      - Removes `get_name_suffix_list()`. Instead set `.suffix_list` in the config hash in `setup()`.
      - Renames `Handlers` to `WayHandlers`.
      - Pass functions instead of strings to `WayHandlers.run()`, so it's possible to mix in your own functions.
      - Reorders arguments to `WayHandlers` functions to match `process_way()`.
      - Profiles must return a hash of profile functions. This makes it easier for profiles to include each other.
      - Guidance: add support for throughabouts
    - Bugfixes
      - Properly save/retrieve datasource annotations for road segments ([#4346](https://github.com/Project-OSRM/osrm-backend/issues/4346)
    - Algorithm)
      - BREAKING: the file format requires re-processing due to the changes on via-ways
      - Added support for via-way restrictions
