+# 5.2.0
+  Changes form 5.2.0 RC2
+   - Bugfixes:
+     - Fixed crash when loading shared memory caused by invalid OSM IDs segment size.
+     - Various small instructions handling fixes
+
+   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.
+         - `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 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`
+
+   - 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.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**
+     - BREAKING: Intersection Classification adds a new file to the mix (osrm.icd). This breaks the fileformat for older versions.
+     - 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.
+     - 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
+
