Eventually yes, but I can imagine a grace period for bugfix release before go to security-only.
Reality might not require it, but I don’t want to close the door on this just yet. Either
way tho, this doesn’t change the discussion at hand.

> If so, this is exactly the same as when we released 1.2, 1.3, and so on. Master is always
latest (FDB, in this case) and there are branches like 1.2.x or 2.0.x if we need to backport
security fixes to make a release there.

One special case is that we are now effectively doing 3.0 and 4.0 in parallel for a bit until
3.0 is out. We just need to decide which version stays in-branch until 3.x is out. I don’t
think there is a clear winner either way.

To deal with the PR awkwardness, we could fork current master into a new repo, make that FDB
CouchDB, and when 3.x ships and gets its 3.x.x branch we merge the other repo back as master,
maybe via a special case where FDB CouchDB master straight out replaces then current couchdb.git
master, and that master is moved to 3.x.x. Will need some ASF Infra help obvs. I would want
to avoid having to merge things back and forth for anything that isn’t kept around (chttpd,
replicator, etc), as nice as Nebraska is, I wouldn’t want to put anyone through a big merge
bonanza again.

Best
