RE: [Zope] Product Update Strategy

..well doing this kindof thing is exactly what I use it for: you write a new version of a product which has attributes in different places in classes, etc, and you need to update old instances.

What do you do with entirely new methods?

Well, if you don't want them installing one more product and an external method, then you're left with __setstate__ hackery which is notoriously unreliable :-S

Installing a python product should be ok, but I'd like to automate the installation of the external method because none of the users currently have management rights. Thanks so far Roché
