[smashed]

Officially you are right, they release it as a stable OS after a few weeks of beta's.

Unofficially any serious user knows to stick to LTS for any production environment. This is by far the most common versions I encounter in the wild and on customer deployment from my experience.

In fact I don't think I ever saw someone using a non-LTS version.

Canonical certainly has these stats? Or someone operating update mirror could infer them? I'd be curious what the real world usage of different Ubuntu versions actually are.
