There is a lot that is not working completely in 1204 at this point. Very little has been tested.
What users can do to help:
We need testers to identify the current issues and file trac tickets at svn.linuxmce.org so the issues can be looked at. Be sure to search for an existing ticket identifying the same issue before creating a new one and then check the ticket regularly to see if there has been any action or questions. This will help devs to trac the issues properly.
And, thank you to anyone who tests and files tickets for us!
ps, Polly: you're doing a great job on the upgrade script.
