    - HTTP:
      - New query parameter for route/table/match/trip plugings:
        `exclude=` that can be used to exclude certain classes (e.g. exclude=motorway, exclude=toll).
        This is configurable in the profile.
    - NodeJS:
      - New query option `exclude` for the route/table/match/trip plugins. (e.g. `exclude: ["motorway", "toll"]`)

      - New optional property for profile table: `classes` that allows you to specify which classes you expect to be used.
        We recommend this for better error messages around classes, otherwise the possible class names are infered automatically.
    - Traffic:
      - If traffic data files contain an empty 4th column, they will update edge durations but not modify the edge weight.  This is useful for
        updating ETAs returned, without changing route selection (for example, in a distance-based profile with traffic data loaded).
    - Infrastructure:
      - New file `.osrm.cell_metrics` created by `osrm-customize`.
    - Debug tiles:
      - Added new properties `type` and `modifier` to `turns` layer, useful for viewing guidance calculated turn types on the map

# 5.11.0
  - Changes from 5.10:
    - Features
      - BREAKING: Added support for conditional via-way restrictions. This features changes the file format of osrm.restrictions and requires re-extraction
    - Internals
      - BREAKING: Traffic signals will no longer be represented as turns internally. This requires re-processing of data but enables via-way turn restrictions across highway=traffic_signals
      - Additional checks for empty segments when loading traffic data files
      - Tunes the constants for turns in sharp curves just a tiny bit to circumvent a mix-up in fork directions at a specific intersection (https://github.com/Project-OSRM/osrm-backend/issues/4331)
    - Infrastructure
      - Refactor datafacade to make implementing additional DataFacades simpler
    - Bugfixes
      - API docs are now buildable again
      - Suppress unnecessary extra turn instruction when exiting a motorway via a motorway_link onto a primary road (https://github.com/Project-OSRM/osrm-backend/issues/4348 scenario 4)
      - Suppress unnecessary extra turn instruction when taking a tertiary_link road from a teritary onto a residential road (https://github.com/Project-OSRM/osrm-backend/issues/4348 scenario 2)
      - Various MSVC++ build environment fixes
      - Avoid a bug that crashes GCC6
      - Re-include .npmignore to slim down published modules
      - Fix a pre-processing bug where incorrect directions could be issued when two turns would have similar instructions and we tried to give them distinct values (https://github.com/Project-OSRM/osrm-backend/pull/4375)
      - The entry bearing for correct the cardinality of a direction value (https://github.com/Project-OSRM/osrm-backend/pull/4353
      - Change timezones in West Africa to the WAT zone so they're recognized on the Windows platform

# 5.10.0
  - 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)
      - Fix conditional restriction grammer parsing so it works for single-day-of-week restrictions ([#4357](https://github.com/Project-OSRM/osrm-backend/pull/4357))
    - Algorithm
      - BREAKING: the file format requires re-processing due to the changes on via-ways
      - Added support for via-way restrictions

# 5.9.2
    - API:
      - `annotations=durations,weights,speeds` values no longer include turn penalty values ([#4330](https://github.com/Project-OSRM/osrm-backend/issues/4330))

# 5.9.1
    - Infrastructure
      - STXXL is not required by default

# 5.9.0
  - Changes from 5.8:
    - Algorithm:
      - Multi-Level Dijkstra:
        - Plugins supported: `table`
        - Adds alternative routes support (see [#4047](https://github.com/Project-OSRM/osrm-backend/pull/4047) and [3905](https://github.com/Project-OSRM/osrm-backend/issues/3905)): provides reasonably looking alternative routes (many, if possible) with reasonable query times.
    - API:
      - Exposes `alternatives=Number` parameter overload in addition to the boolean flag.
      - Support for exits numbers and names. New member `exits` in `RouteStep`, based on `junction:ref` on ways
      - `Intersection` now has new parameter `classes` that can be set in the profile on each way.
    - Profiles:
      - `result.exits` allows you to set a way's exit numbers and names, see [`junction:ref`](http://wiki.openstreetmap.org/wiki/Proposed_features/junction_details)
      - `ExtractionWay` now as new property `forward_classes` and `backward_classes` that can set in the `way_function`.
         The maximum number of classes is 8.
      - We now respect the `construction` tag. If the `construction` tag value is not on our whitelist (`minor`, `widening`, `no`) we will exclude the road.
    - Node.js Bindings:
      - Exposes `alternatives=Number` parameter overload in addition to the boolean flag
      - Expose `EngineConfig` options in the node bindings
    - Tools:
      - Exposes engine limit on number of alternatives to generate `--max-alternatives` in `osrm-routed` (3 by default)
    - Infrastructure
      - STXXL is not required to build OSRM and is an optional dependency for back-compatibility (ENABLE_STXXL=On)
      - OpenMP is only required when the optional STXXL dependency is used
    - Bug fixes:
      - #4278: Remove superflous continious instruction on a motorway.

# 5.8.0
  - Changes from 5.7
    - API:
      - polyline6 support in request string
      - new parameter `approaches` for `route`, `table`, `trip` and `nearest` requests.  This parameter keep waypoints on the curb side.
        'approaches' accepts both 'curb' and 'unrestricted' values.
        Note : the curb side depend on the `ProfileProperties::left_hand_driving`, it's a global property set once by the profile. If you are working with a planet dataset, the api will be wrong in some countries, and right in others.
    - NodeJs Bindings
      - new parameter `approaches` for `route`, `table`, `trip` and `nearest` requests.
    - Tools
      - `osrm-partition` now ensures it is called before `osrm-contract` and removes inconsitent .hsgr files automatically.
    - Features
      - Added conditional restriction support with `parse-conditional-restrictions=true|false` to osrm-extract. This option saves conditional turn restrictions to the .restrictions file for parsing by contract later. Added `parse-conditionals-from-now=utc time stamp` and `--time-zone-file=/path/to/file`  to osrm-contract
      - Command-line tools (osrm-extract, osrm-contract, osrm-routed, etc) now return error codes and legible error messages for common problem scenarios, rather than ugly C++ crashes
      - Speed up pre-processing by only running the Lua `node_function` for nodes that have tags.  Cuts OSM file parsing time in half.
      - osrm-extract now performs generation of edge-expanded-edges using all available CPUs, which should make osrm-extract significantly faster on multi-CPU machines
    - Files
      - .osrm.nodes file was renamed to .nbg_nodes and .ebg_nodes was added
    - Guidance
      - #4075 Changed counting of exits on service roundabouts
    - Debug Tiles
      - added support for visualising turn penalties to the MLD plugin
      - added support for showing the rate (reciprocal of weight) on each edge when used
      - added support for turn weights in addition to turn durations in debug tiles
    - Bugfixes
      - Fixed a copy/paste issue assigning wrong directions in similar turns (left over right)
      - #4074: fixed a bug that would announce entering highway ramps as u-turns
      - #4122: osrm-routed/libosrm should throw exception when a dataset incompatible with the requested algorithm is loaded
      - Avoid collapsing u-turns into combined turn instructions

# 5.7.1
    - Bugfixes

    - 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

# 5.6.3

      - Fix #3515 adjusted number of `nodes` in `annotation`
      - Fix #3605 Fixed a bug that could lead to turns at the end of the road to be suppressed
      - Fix #2844 handle up to 16777215 code units in OSM names
    - Infrastructure
      - Support building rpm packages.
    - Guidance
      - No longer emitting turns on ferries, if a ferry should use multiple docking locations
    - Profiles
      - Removed the `./profile.lua -> ./profiles/car.lua` symlink. Use specific profiles from the `profiles` directory.
      - `properties` object has a new `weight_name` field, default value is "duration"
      - `properties` object has a new `weight_precision` field that specifies a decimal precision of edge weights, default value 1
      - In `way_function` the filed `forward_rate` and `backward_rate` of `ExtractionWay` can now be set.
        They have the same interpretation for the way weight as `forward_speed` and `backward_speed` for the edge duration.
        The unit of rate is meters per weight unit, so higher values will be prefered during routing.
      - `turn_function` now does not return an integer but takes in a `ExtractionTurn` object and can modify the `weight` and `duration` fields
      - `segment_function` now takes in a `ExtractionSegment` object and can modify `weight` and `duration` fields
      - `properties.uturn_penalty` is deprecated. Set it in the `turn_function`. The turn type is exposed as `ExtractionTurn::direction_modifier`.
      - `properties.traffic_light_penalty` is deprecated. Traffic light penalties now need to be set over in the turn function.
         Each turn with a traffic light is marked with `ExtractionTurn::has_traffic_light = true`.
      - Renamed the helper file `profiles/lib/directional.lua` to `profiles/lib/tags.lua` since it now provides more general tags parsing utility functions.
      - The car and foot profiles now depend on the helper file `profiles/lib/handlers.lua`.
    - Infrastructure
      - Disabled link-time optimized (LTO) builds by default. Enable by passing `-DENABLE_LTO=ON` to `cmake` if you need the performance and know what you are doing.
      - Datafile versioning is now based on OSRM semver values, rather than source code checksums.
        Datafiles are compatible between patch levels, but incompatible between minor version or higher bumps.
      - libOSRM now creates an own watcher thread then used in shared memory mode to listen for data updates
    - Tools:
      - Added osrm-extract-conditionals tool for checking conditional values in OSM data
    - Trip Plugin
      - Added a new feature that finds the optimal route given a list of waypoints, a source and a destination. This does not return a roundtrip and instead returns a one way optimal route from the fixed source to the destination points.

# 5.5.1
  - Changes from 5.5.0
    - API:
      - Adds `generate_hints=true` (`true` by default) which lets user disable `Hint` generating in the response. Use if you don't need `Hint`s!
    - Bugfixes
      - Fix #3418 and ensure we only return bearings in the range 0-359 in API responses
      - Fixed a bug that could lead to emitting false instructions for staying on a roundabout

# 5.5.0
  - Changes from 5.4.0
    - API:

      - Shared memory now allows for multiple clients (multiple instances of libosrm on the same segment)
      - Polyline geometries can now be requested with precision 5 as well as with precision 6
    - Profiles
      - the car profile has been refactored into smaller functions
      - get_value_by_key() is now guaranteed never to return empty strings, nil is returned instead.
      - debug.lua was added to make it easier to test/develop profile code.
      - `car.lua` now depends on lib/set.lua and lib/sequence.lua
      - `restrictions` is now used for namespaced restrictions and restriction exceptions (e.g. `restriction:motorcar=` as well as `except=motorcar`)
      - replaced lhs/rhs profiles by using test defined profiles
      - Handle `oneway=alternating` (routed over with penalty) separately from `oneway=reversible` (not routed over due to time dependence)
      - Handle `destination:forward`, `destination:backward`, `destination:ref:forward`, `destination:ref:backward` tags
      - Properly handle destinations on `oneway=-1` roads
    - Guidance
      - Notifications are now exposed more prominently, announcing turns onto a ferry/pushing your bike more prominently
      - Improved turn angle calculation, detecting offsets due to lanes / minor variations due to inaccuracies
      - Corrected the bearings returned for intermediate steps - requires reprocessing
      - Improved turn locations for collapsed turns
      - Sliproad classification refinements: the situations we detect as Sliproads now resemble more closely the reality

      - fixed a bug in the tile plugin that resulted in discovering invalid edges for connections
      - improved error messages when missing files during traffic updates (#3114)
      - For single coordinate geometries the GeoJSON `Point` encoding was broken. We now always emit `LineString`s even in the one-coordinate-case (backwards compatible) (#3425)
    - Debug Tiles
      - Added support for turn penalties
    - Internals
      - Internal/Shared memory datafacades now share common memory layout and data loading code
      - File reading now has much better error handling
    - Misc

      - Reduced semantic of merge to refer only to merges from a lane onto a motorway-like road
      - new `ref` field in the `RouteStep` object. It contains the reference code or name of a way. Previously merged into the `name` property like `name (ref)` and are now separate fields.
    - Bugfixes
      - Fixed an issue that would result in segfaults for viaroutes with an invalid intermediate segment when u-turns were allowed at the via-location
      - Invalid only_* restrictions could result in loss of connectivity. As a fallback, we assume all turns allowed when the restriction is not valid

   Changes from 5.1.0
   - API:
     - new parameter `annotations` for `route`, `trip` and `match` requests.  Returns additional data about each
       coordinate along the selected/matched route line per `RouteLeg`:
         - duration of each segment
         - distance of each segment
         - OSM node ids of all segment endpoints
     - Introducing Intersections for Route Steps. This changes the API format in multiple ways.

     - `result.pronunciation` allows you to set way name pronunciations
     - `highway=motorway_link` no longer implies `oneway` as per the OSM Wiki

   - Infrastructure:
     - BREAKING: Changed the on-disk encoding of the StaticRTree to reduce ramIndex file size. This breaks the **data format**
     - BREAKING: Intersection Classification adds a new file to the mix (osrm.icd). This breaks the fileformat for older versions.

       - Open sockets with SO_REUSEPORT to allow multiple osrm-routed processes serving requests from the same port.
       - Add SIGNAL_PARENT_WHEN_READY environment variable to enable osrm-routed signal its parent with USR1 when it's running and waiting for requests.
     - Disable http access logging via DISABLE_ACCESS_LOGGING environment variable.

   - Guidance:
     - BREAKING: modifies the file format with new internal identifiers
     - improved detection of turning streets, not reporting new-name in wrong situations
     - improved handling of sliproads (emit turns instead of 'take the ramp')
     - improved collapsing of instructions. Some 'new name' instructions will be suppressed if they are without alternative and the segment is short

   - Bugfixes
     - fixed broken summaries for very short routes

# 5.2.0 RC2
   Changes from 5.2.0 RC1

   - Guidance:
     - improved handling of sliproads (emit turns instead of 'take the ramp')
     - improved collapsing of instructions. Some 'new name' instructions will be suppressed if they are without alternative and the segment is short
     - BREAKING: modifies the file format with new internal identifiers

   - API:
     - paramater `annotate` was renamed to `annotations`.
     - `annotation` as accidentally placed in `Route` instead of `RouteLeg`
     - Support for destination signs. New member `destinations` in `RouteStep`, based on `destination` and `destination:ref`
     - Support for name pronunciations. New member `pronunciation` in `RouteStep`, based on `name:pronunciation`
     - Add `nodes` property to `annotation` in `RouteLeg` containing the ids of nodes covered by the route

   - Profile changes:
     - `result.destinations` allows you to set a way's destinations
     - `result.pronunciation` allows you to set way name pronunciations
     - `highway=motorway_link` no longer implies `oneway` as per the OSM Wiki

   - Infrastructure
     - BREAKING: Changed the on-disk encoding of the StaticRTree to reduce ramIndex file size. This breaks the **data format**

   - Bugfixes
     - fixed broken summaries for very short routes

# 5.2.0 RC1
   Changes from 5.1.0

   - API:
     - new parameter `annotate` for `route` and `match` requests.  Returns additional data about each
       coordinate along the selected/matched route line.
     - Introducing Intersections for Route Steps. This changes the API format in multiple ways.
         - `bearing_before`/`bearing_after` of `StepManeuver` are now deprecated and will be removed in the next major release
         - `location` of `StepManeuvers` is now deprecated and will be removed in the next major release
         - every `RouteStep` now has property `intersections` containing a list of `Intersection` objects.

   - Profile changes:
     - duration parser now accepts P[n]DT[n]H[n]M[n]S, P[n]W, PTHHMMSS and PTHH:MM:SS ISO8601 formats.

   - Infrastructure:
     - Better support for osrm-routed binary upgrade on the fly [UNIX specific]:
       - Open sockets with SO_REUSEPORT to allow multiple osrm-routed processes serving requests from the same port.
       - Add SIGNAL_PARENT_WHEN_READY environment variable to enable osrm-routed signal its parent with USR1 when it's running and waiting for requests.
     - BREAKING: Intersection Classification adds a new file to the mix (osrm.icd). This breaks the fileformat for older versions.
     - Disable http access logging via DISABLE_ACCESS_LOGGING environment
       variable.

   - Guidance:
     - improved detection of turning streets, not reporting new-name in wrong situations

# 5.1.0
   Changes with regard to 5.0.0

   - API:
     - added StepManeuver type `roundabout turn`. The type indicates a small roundabout that is treated as an intersection
        (turn right at the roundabout for first exit, go straight at the roundabout...)
     - added StepManeuver type `on ramp` and `off ramp` to distinguish between ramps that enter and exit a highway.
     - reduced new name instructions for trivial changes
     - combined multiple turns into a single instruction at segregated roads`

   - Profile Changes:
    - introduced a suffix_list / get_name_suffix_list to specify name suffices to be suppressed in name change announcements
    - street names are now consistently assembled for the car, bike and walk profile as: "Name (Ref)" as in "Berlin (A5)"
    - new `car.lua` dependency `lib/destination.lua`
    - register a way's .nodes() function for use in the profile's way_function.

   - Infrastructure
    - BREAKING: reordered internal instruction types. This breaks the **data format**
