Why not ask your question on the new OpenStreetMap Community Forum?

I have a route between generated by osrm between 2 locations. The route changed when updating from OSRM 4.9.O to 5.3.3.

I wanted to compare the response from:

http://localhost:5000/route/v1/driving/4.325217,50.901073;4.422702,51.191058?          steps=true&alternatives=false&annotations=true

However the datasources , weight and speed attributes are missing.

Is there a better way to find out why a route changed?

OSRM has significantly changed between 4.9.0 and 5.3.3. In particular, the "profiles" which assign different speeds/weightings to each section of road have changed. This means that the newer version will calculate different journey times for each road, and may therefore choose a different route because it now reckons it's faster.

You can see changes made to the profiles here: https://github.com/Project-OSRM/osrm-backend/commits/master/profiles
