Plone 3.2 has been completely converted to eggs, that is what enables this enhancement in the installation story of Plone. As stated in the release notes (http://plone.org/products/plone/releases/3.2.1), Plone will no longer be distributed as a tarball of Zope Products.

Standard Python packaging will improve dependency handling and make future installations easier, that is why it was most awaited.

This change requires little attention by who is updating old installations. In particular, users of past Windows installers should not try to simply install on top of the old Windows installation. The move to a buildout-based installer has changed the layout of the subdirectories inside the installation.

The best way to procede is:

• do a new installation,
• get it working with all required products,
• then copy your old Data.fs file over the matching file in the new installation.
