There's a question below that I want opinions on, so I'm forwarding
this note here that I sent to the distutils-sig. I'd prefer answers
there, but I'll take them here.
Specifically: Should I make it the default policy for buildout to
prefer final releases? I think this is the right thing to do in the
long run, however, it will cause buildouts that implicitly use non-
final eggs to be downgraded. This will cause some pain until people
make adjustments.
Thoughts?

Subject: Preferring final releases
Currently, when looking for a new release, easy_install and
buildout look for the newest distributions that satisfy a
requirement. They will, for example, prefer a newer development
release or preliminary release (dev, alpha, beta, or rc) over a
final release. I don't think this is a good default policy.
In buildout, I'm going to add an option, prefer-final, to control
this. If this option is true, then buildout will prefer final
distributions over non-final distributions. It will choose the
latest final version that meets a requirement if there is one.
Maybe buildout should make this the default. (Thoughts?) In any
case, since buildout lets people create their own defaults for
buildout options, people will be able to choose any default they
wish. With this option enabled, you'll be able to get a non-final
distribution by explicitly requiring it.
I think easy_install and setuptools should provide a similar option
and provide a way (presumably through setup.cfg) to make it the
default. For backward compatibility reasons, it may not be
possible to make this the default policy for setuptools, although,
arguably, it is a better default.

Note that for buildout, what I said above isn't accurate. :)
Buildout prefers develop distributions over non-develop
distributions. It will currently choose a develop distribution
that meets a requirement, if there is one. If prefer-final is
enabled, then buildout will choose the latest develop distribution
that satisfies the requirement, if there is one, otherwise, it will
pick the latest final distribution that meets a requirement, if
there is one, otherwise, it will pick the latest distribution that
meets a requirement.
