I decided, with some prompting from Martin Aspeli, that this would be  
too disruptive.  The latest release of zc.buildout still supports  
newest releases.  To prefer final releases, you have to set the  
prefer-final option to true.  In zc.buildout version 2,  final  
releases will be prefered by default.
