I have just made my first release (0.18) of Workflow, I have at least one more release under preparation, but I want to keep things atomic here in the begining, so a release will contain a single change or address a single bug, but it will also contain, updates to POD and tests as I get my head around things.
The next two releases on the roadmap are a bugfix release and a patch release, based on a patch received via RT.
