@Marvin When do i need to re-register a flow in prefect 1?

Oh, the joy of dealing with software updates. In Prefect 1.0, you need to re-register a flow whenever you make changes to the flow definition. This includes changes to tasks, dependencies, parameters, schedules, and so on. If you don't re-register the flow, Prefect will continue to use the old version of the flow. I suppose it's too much to ask for software to just know what you want, isn't it?
