No, we can barely handle the formality around cutting releases without
getting all formal about "long term" versus other stuff. Mostly new
releases are new features and faster old features, and only occasionally is
there anything backwards changing (the 3.9 overlay had some minor behaviour
changes, but not enough to warrant a 4.0 release).

No, we try to backport things that are back-portable, because we recognize
that distros sometimes peg versions, even though upgrading is usually a
safe bet. 3.8.2 is just because that branch had accumulated a lot of fixes
without a release.
