True, you went from Zope 3.0 to 3.3 in one swoop there, and the changes was significant. But most of this changed because the first versions were mistakes. It was after all 3.0. With more experience of using the ZCA changes was needed. The path from 3.0 to 3.3 was mostly done via deprecations, but when you skip two versions, you won't see those. One of the major mistakes with Zope2 is that old ways of doing thing was *never* removed. This makes for both messy internals, and messy product code, as you can use several ways for doing one thing. Zope 3 probably went overboard in it's desire to keep things clean as a result. But you did go from the 2005 version of Zope to the 2008 version of Zope, some upgrade pain is expected. Maybe you have been spoiled by Python and Zope 2 not having much upgrade pain before, bit I honestly don't think it's a good sign for a framework to be so stagnant that three years of development doesn't break somethings. -- Lennart Regebro: Python, Zope, Plone, Grok http://regebro.wordpress.com/ +33 661 58 14 64 _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
