nf-prov 1.2.0 has been released! The config settings have been overhauled to allow multiple output formats in a single run.
I am planning to retire the "legacy" format and replace it with a "manifest" format that is more comprehensive. It will contain the same information as the BCO format but also include metadata which BCO seems to overlook. Let me know if you have any suggestions for this format and I will try to incorporate them
