Delivery carrier settings now include an environment option to choose whether integrations use test APIs or production APIs. This helps businesses safely validate shipping carrier setups before going live, reducing the risk of real shipment or billing mistakes during testing.

This field is used in all delivery carriers to determine if they call
the test or the production API.

Delivery staff can now set or adjust a package type and shipping weight during packing or afterward. This helps carriers receive more accurate package information and centralizes packaging setup across shipping workflows.
