It is already documented, but most people file and respond to bugs without
reading the documentation (and why should they have to?). Perhaps the only
way to track regressions more accurately would be to represent them as
first-class data in Launchpad. This is tricky, though, as we've learned
that the more visible a knob is, the more it is turned, regardless of
whether it is appropriate or not. If the data is too noisy, it becomes
useless (this is why Importance is controlled).

I agree that we need to communicate better around our release activity,
particularly with LTS. We made operational provisions for the new approach,
for example delaying automatic upgrades from 6.06 LTS until 8.04.1, but the
differences between 8.04 LTS, 7.10 and 6.06 LTS were perhaps not clear
enough to everyone affected.

I by no means imply that 8.04 was not ready to use. There were some flaws,
which there always are in software releases, and in my view we addressed
them appropriately with updates and 8.04.1.
To you, "LTS" may mean "so stable", but to another, it means that problems
are actively fixed (which implies some change and therefore instability)
even after release. One thing it can never mean is that there are no bugs
in it, for that is a practical impossibility.
