So...we are on 2.8.10 and our biggest app on our site is a ZClass based news object. How close will this provide functionality to just drop our data.fs into 2.12 and have those zclasses work? This is huge news! Thanks Dieter!!!!
For long term stability and maintainability I would strongly recommend rewriting your application to remove ZClasses. Depending on your application(s) this can be a non-trivial task, but once it is done you can return to standard zope releases. This is a business risk/reward situation: how important are the ZClass apps to your business? Can you afford to have them stop working? Are willing to maintain your own ZClass patches (Dieter has provided a starting point, but what if Dieter "gets hit by a bus")? I have rewritten ZClass apps twice now, and it can be a serious PITA, but the peace-of-mind, ongoing product stability and maintainability was well worth it. Jonathan
