We are actually improving the situation. Right now in Plone 3.x you can
have three different version numbers: the package version in setup.py,
the Zope product version in version.txt and the GenericSetup profile
version in metadata.xml. This created a confusing mix, which was not
helped by Plone itself getting some concepts wrong.
As of Plone 3.3 you only have two versions: the package version as
defined in setup.py (with a fallback to version.txt for old-style
products that are not shipped as packages) and the profile version in
metadata.xml. There was a big discussion about the relevance of having
separate versions for the code and the configuration on the
plone-developers list. If you are interested in the rational I'ld
encourage you to browse through the mailinglist archives.
