[Zope] product security changes from 2.8 to 2.8.5 ?

Hello I recently moved my zope product developed on a 2.8 server on to a 2.8.5 server, and all of my python code is no longer being published out. In the past I had been using a doc string """ doc """ to make methods accessible. I realize this is not the proper procedure, but it worked. Now, on the 2.8.5 server, all of these are refused. I've been going through and doing security.declarePublic('methodname') on everything I want to be public, but it does not appear to have any effect. Are there any other changes that I need to make to my product in order to get back the functionality I had previously? Am I even looking in the right place? Thanks for any tips -e-
