It seems that 188.8.131.52 moved parking settings to the database. The upgrade removed any mention of park from features.conf, they remain in the backup file features.conf.bak
It changed the default behavior of park in the first available to park in next available.
How do you change it back, we can not find the option in the GUI. In MTE you can find it in the tenant management.
We tried to add the park options back to features.conf but the system does not use them, i.e. limit the park orbits to 701-702.
