[Zope] [Epoz] Which version have I to use ?

Hi folks, I tried to integrate epoz in my Zope2 developments, but : 1) I don't understand which version to choose (Epoz 0.7.x or epoz 1.x ?). 2) After the install of epoz 1.0.1 and FileSystemSite 1.3, I can't create the 'epoz editor' (it doesn't appear in the addable object list). I am in trouble. I need some help !
