Proposals
How do proposal revisions work?
Change a finalized or accepted proposal by creating a new revision.
Finalized and accepted proposals can't be edited. To change one, create a revision: it starts as a draft copy with the next revision number.
When the new revision is finalized, the older one is marked superseded and its shared link shows that a newer version exists.
The revision history on the proposal lists every version, which one was accepted and by whom.
