Changed the default policy back to what it was to avoid breakage in

  existing buildouts.  Use::

[buildout]
    prefer-final = true

to get the new policy.  The new policy will go into effect in
  buildout 2.

Final releases prefered
-----------------------
By default, when searching for new releases, final releases are
prefered. If there are final releases that satisfy distribution
requirements, then those releases are used even if newer non-final
releases are available. The buildout prefer-final option can be used
to override this behavior. If a buildout prefer-final option is given
with the value "false", then, when looking for distributions, the
newest will be used regardless of whether or not they are final.
Prefering Final Releases
------------------------
Currently, when searching for new releases, the newest available
release is used. This isn't usually ideal, as you may get development
releaes or alpha releases not ready to be widely used. You can
request that final releases be prefered using the prefer final option
in the buildout section::
[buildout]
...
prefer-final = true
When the prefer-final option is set to true, then when searching for
new releases, final releases are prefered. If there are final
releases that satisfy distribution requirements, then those releases
are used even if newer non-final releases are available. The buildout
prefer-final option can be used to override this behavior.
In buildout version 2, final releases will be prefered by default.
You will then need to use a false value for prefer-final to get the
newset releases.
