Back in the mists of time (probably about 10 years ago), I remember that editing an epub in Sigil resulted in Sigil adding some of its own fields to the metadata. I've been reviewing epubs edited with recent versions of Sigil, and I don't seem to see this happening anymore. Can anyone confirm (or deny) this? I know that what I really need to do is a line by line before and after code comparison, and I will do it soon, but I don't have time right now. Thanks
