> So currently charmhub only supports ubuntu series
Is there a roadmap for charmhub to support other OSes?

according to [0], the `series` entry in the metadata is going to be deprecated. I though Charmhub already had support for the new `charmcraft.yaml` `bases` entry, but apparently it doesn't? Charmcraft requires us to specify the `bases`, having to also add `series` sounds like duplicating information, or I am missing something?

Should we always add the `series` entries then?
