Hello, Do you know when is the prefect 2.0 expected to be released for production use?

Beta release around end of this month

Thanks for the quick reply. I've noticed that prefect 2.0 will support rest API. The previous version is only supporting GraphQL API. Do we have some documentation and examples on how to use GraphQL to run prefect flows?

Yeah. See this

Cool! this is useful indeed. I don't see an example on how to get the versionGroupID though. I know that this is an UID that is generated when registering a flow. This is not the flowID right?

Yes because version group id will not change when you re-register the flow
