I think if the committer omits an "Author" tag, but credits a non-committer as "Co-Author", then both the committer and the non-committer should be considered authors and credited in the release notes. What would be the use-case for a sole non-committer "Co-Author" (as opposed to just crediting the non-committer as "Author") otherwise be? Michael
