# 5.2.0 RC2 Changes from 5.2.0 RC1 - Guidance: - improved handling of sliproads (emit turns instead of 'take the ramp') - 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`. - Profile changes: - `result.destinations` allows you to set a way's destinations - 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. - Support for name pronounciations. New member `pronounciation` in `RouteStep`, based on `name:pronounciation`. - 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. - `result.pronounciation` allows you to set way name pronounciations. - 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** - BREAKING: Changed the on-disk encoding of the StaticRTree for better performance. This breaks the **data format** - Fixes: - Issue #2310: post-processing for local paths, fixes #2310 - Issue #2309: local path looping, fixes #2309 - Issue #2356: Make hint values optional - Issue #2349: Segmentation fault in some requests - Issue #2335: map matching was using shortest path with uturns disabled - Issue #2193: Fix syntax error position indicators in parameters queries - Fix search with u-turn - PhantomNode packing in MSVC now the same on other platforms - Summary is now not malformed when including unnamed roads - Emit new-name on when changing fron unanmed road to named road # 5.0.0 Changes with regard 5.0.0 RC2: - API: - if `geometry=geojson` is passed the resulting geometry can be a LineString or Point depending on how many coordinates are present. - the removal of the summary field was revered. for `steps=flase` the field will always be an empty string. Changes with regard to 4.9.1: - API: - BREAKING: Complete rewrite of the HTTP and library API. See detailed documentation in the wiki. - BREAKING: The default coordinate order is now `longitude, latidue`. Exception: Polyline geometry which follow the original Google specification of `latitdue, longitude`. - BREAKING: Polyline geometries now use precision 5, instead of previously 6 - BREAKING: Removed GPX support - New service `tile` which serves debug vector tiles of the road network - Completely new engine for guidance generation: - Support for highway ramps - Support for different intersection types (end of street, forks, merges) - Instruction post-processing to merge unimportant instructions - Improved handling of roundabouts - Tools: - BREAKING: Renamed osrm-prepare to osrm-contract - BREAKING: Removes profiles from osrm-contract, only needed in osrm-extract. - Abort processing in osrm-extract if there are no snappable edges remaining. - Added .properties file to osrm-extract ouput. - Enables the use of multiple segment-speed-files on the osrm-contract command line - Profile changes: - Remove movable bridge mode - Add `maxspeed=none` tag to car profile. - A `side_road` tag support for the OSRM car profile. - Fixes: - Issue #2150: Prevents routing over delivery ways and nodes - Issue #1972: Provide uninstall target - Issue #2072: Disable alternatives by default and if core factor < 1.0 - Issue #1999: Fix unpacking for self-loop nodes not in core. - Infrastructure: - Cucumber test suit is now based on cucumber-js, removes Ruby as dependency - Updated to mapbox/variant v1.1 - Updated to libosmium v2.6.1 - Remove GeoJSON based debugging output, replaced by debug tiles # 5.0.0 RC2 - Profiles: - `properties.allow_uturns_at_via` -> `properties.continue_straight_at_waypoint` (value is inverted!) - API: - Removed summary from legs property - Disable steps and alternatives by default - Fix `code` field: 'ok' -> 'Ok' - Allow 4.json and 4.3.json format - Conform to v5 spec and support "unlimited" as radiuses value. - `uturns` parameter was replaced by `continue_straight` (value is inverted!) - Features: - Report progress for gennerating edge expanded edges in the edge based graph factory - Add maxspeed=none tag to car profile. - Optimize StaticRTree code: speedup 2x (to RC1) - Optimize DouglasPeucker code: speedup 10x (to RC1) - Optimize WebMercator projection: speedup 2x (to RC1) - Bugs: - #2195: Resolves issues with multiple includedirs in pkg-config file - #2219: Internal server error when using the match plugin - #2027: basename -> filename - #2168: Report correct position where parsing failed - #2036: Add license to storage and storage config exposed in public API - Fix uturn detection in match plugin - Add missing -lz to fix linking of server-tests # 5.0.0 RC1 - Renamed osrm-prepare into osrm-contract - osrm-contract does not need a profile parameter anymore - New public HTTP API, find documentation [here](https://github.com/Project-OSRM/osrm-backend/wiki/New-Server-api) - POST support is discontinued, please use library bindings for more complex requests - Removed timestamp plugin - Coordinate order is now Longitude,Latitude - Cucumber tests now based on Javascript (run with `npm test`) - Profile API changed: - `forward_mode` and `backward_mode` now need to be selected from a pre-defined list - Global profile properties are now stored in a global `properties` element. This includes: - `properties.traffic_signal_penalty` - `properties.use_turn_restrictions` - `properties.u_turn_penalty` - `properties.allow_u_turn_at_via`
