[Zope] The most stable version of Zope?

I'm running Zope 2.0.0 here on RedHat 6.0/Intel. My plan was to wait with upgrade to 2.1.0 Final, but now my Zope has lost the node in its tree that I was working on. Well, the node is there, but its empty and when I click it, right pane says: "Zope Error Zope has encountered an error while publishing this resource. KeyError Sorry, a Zope error occurred." I have backups (as usually not tested ;-/), but if the ODB is beginning to corrupt I better do something soon. So now I want to upgrade to either 2.0.1 or a 2.1 beta. Which version should I go with? Secondary question: Is there a tool for straightening the ODB up again? -- Best regards / mvh., Steen Suder sysadm kollegie6400.dk OpenSource - Sign of the time
