[Zope-dev] Allowed Product Changes

I'm building some Products in python and find it very difficult as I
never know when a source change is going to render the data for existing
instances invalid. Sometimes when this happens it takes down the
containing folder as well.

Are there any obvious do's and don'ts and how-tos when modifying an
existing product? What makes instances break for example?
