To clarify, does that mean you want to entirely drop the previous
proposal of having multiple supported versions with packages like
"docker", "docker-1.5", or "docker-stable", and instead we'll just
have a single supported "docker" which gets new major versions for
stable releases, at least as long as they stay compatible in the sense
below?

If that's possible, I much prefer this to the previous proposal, which
IMHO made things even worse and more labor-intense and didn't address
the fundamental problem at all.

That sounds good to me. If the primary/intended way of consuming
docker is to always run the latest upstream stable release, then
docker workloads should not be too surprised if existing rollouts
suddenly find a new docker version.

If the backwards compatibility is given/tested, this sounds much
more practical, less confusing, and better to me indeed.

Thanks!

Martin
