It is not necessary.
You just tag your version and only merge the changes for your fix,
even when it is spread out.

No, Markus, your proposal was a lot better.

This is basically true.

Well we have to start to tag modules which we know are stable.
So there has to be one starting point for the stable branch.
And Markus has to decide which modules get in there.
Later we can add more when we know they are ready to be included.
To rephrase it again: Yes we have to decide which module is stable
and which not.

No. I advise against Justin's idea. :)

We need one continous stable branch until 5.0.0 is released.
After that we have to rethink a couple of things. I also do not
think that we need the same setup for the 5.1 _tree_.

No, 5.1 has to become a fresh tree, no branch.

True, and the other way gives you more control and is therefor saver.

I don't think so, we have the same problem as before, the control
over what bugfix gets in is not fine grained enough.
