Feature summary: Allow newsletter extension to publish issues that point to page sections (as opposed to only being limited to pages).
Use case(s) : Reported by User:Gryllida on MW:Newsletter Talk page about having using the extension to send Echo notification to a group of subscribers, but in this case, with page sections (instead of new pages) as issues.
Benefits: Seems like we had a discussion about it back during the original discussions around the Newsletter extension. In general, this should make the extension more flexible (I guess)?
