I actually prefer Loaden's suggestion, but in the interest of avoiding exactly
the confusion that you're seeing now, we preferred to remove "master"
completely. This way, there's no ambiguity.

Some people didn't like "next". I don't mind it.

Yeah, right... We've been feature-complete for a while. So why is Qt 5.0.0 not
released yet?
Feature-complete means all features (for this particular project) are
developed and unit tested. It means they've been tested to work according to
the design on, at *least*, the reference platforms, though we're likely to be
a little lax here for small features and allow the integration to be the test
on the reference platforms.
In particular, it does not mean there are no bugs. And also note that I did
not say anything about API reviews, though a minimal review of larger features
is necessary, of course. The point of an alpha release is to get feedback on
the *functionality* and whether it actually serves the purpose it was intended
to. That means all the code in the dev branch, which is alpha quality and
ready to go into beta, must be ready for that kind of feedback.
Incomplete features, like stuff that doesn't compile, doesn't work on all
reference platforms, has missing implementations, misses documentation or unit
testing, hasn't had even a minimal API review, does not belong in the dev
branch.

We cannot design an idiot-proof system. I'm not calling our contributors
idiots: in fact, quite to the contrary, I'm calling our contributors
reasonable and intelligent people, who will realise that there are more
branches they could look at.
Moreover, complete newbies will need some handholding and then it falls to the
existing contributors to point out where solutions might be developed already.
This post of mine here is intended to become part of the wiki, which is that
workflow documentation you're looking for.

Yeah, and so? I prefer to design a system that has the most chance of being
stable, at the cost of having some slight mistakes in redeveloping, than
developing a system that has a bigger chance of generating unstable code and
longer release times. In my opinion, the human mistake factor is much bigger
and has a larger impact in the stabilisation process.

I don't get it. I don't see a contradiction here. The alpha quality code is
not bug-free nor is it stable. It's just feature complete and does at least
what it intended to do.
