You can always know the minimum version. If you just released
3.4.2, I think it's sensible to point the next release to 3.4.3.
If you later decide that you really need a feature release, you
can always bump to 3.5.0a1 (which would be the first release in
the 3.5.x series).
Gary and Benji made me pay attention to this point. :)
I *really* don't like setting the version to the number for the
next release, since one often doesn't know what it is.
Maybe. However, when you do the actual release then, you're still
going to have to find out which version number to use. On release
branches this is a trivial step, of course: You just look at the
latest tagged version and increment accordingly. On the trunk it
might be trickier. After 1.0, do we have 1.1? Or 2.0?
Maye this aspect isn't such a big deal, though.
Why not leave the version totally out of the setup.py in the trunk?
Benji and Gary won me over to this point of view. :)
There's a *really* good reason for putting the upcoming version
number in setup.py, though: development eggs.
Let's say X depends on Y and I'm developing them simultaneously as
development eggs in one sandbox (e.g. buildout). I add a feature to Y
that I'd like to use in X. That means I'll have to change X's version
dependency regarding Y so that it now depends on Y>a.b where a.b is
the latest release that didn't have the feature I added.
Will Y with the setup.py stating version='unreleased' satisfy the
Y>a.b requirement that X (rightfully) has? If not, then I think we
have a problem. If yes, then I find that very confusing.
I know that if Y's setup.py stated version='a.b-dev', it will work.
This what my guide currently suggests (including taking it out just
for release tags).
After branching for a release we can set the version (e.g., 1.2),
make a release, and tag the branch.
We should not require branches. I would only bother creating
maintenance branches when they are needed.

Z, B, G, and I propose the following:
Who's Z? :)
- Leave the version # out of setup.py on the trunk and on branches.
When it is time to make a release, either from the trunk or from a
maint branch:
- Update changes.txt, adding a heading for the new # and date
- Create a tag
- check out or switch to the tag
- Set the version in setup.py on the tag. Check it in.
- Make the release from the tag.
I could live with that, even with the fact that you'd be modifying a
tag, as long as it's done in this exact order and the only
modificdations to a tag woudl be setting setup.py.
I still see the development egg case the best argument for putting
the next anticipated version number into setup.py. I think the
compromise of version number + 'dev' marker would work best.
