Flow auto-reading changes made to workspaces in Form

Hi Group,

Imagine I create a workspace in Form which is then published to Flow. I'd then run this via Flow, and it runs fine. But if I then make a change in the original workspace in Form (even a tiny change like change the destination of a writer, or add a new transformer somewhere), do I then have to republish the workspace from Form to Flow? Or does Flow automatically pick up on changes made to the workspace in Form?

Thanks,

Stuart
