Flowminder/FlowKit: 1.17.1

Added

• Added get_aggregation_unit server action, for getting the aggregation unit associated with a query specification. #5141

• nocturnal_events now expects a night_hours parameter with nested sub-fields start_hour and end_hour, instead of two parameters night_start_hour and night_end_hour.
• Spatial units with a mapping table now only include cells that appear in the mapping table. #5360

• Invalid sub-query specs nested within a modal_location spec now raise appropriate validation errors, instead of being masked by internal flowmachine server errors. #4816
