[BUG?]Upgrading 3.2 to 3.3alpha

A break from the ideological wars -- here's what may be a real (at 
least less controversial) bug.

I seem to be unable to upgrade the most current published version of 
Squeak 3.2 to 3.3.  Am I missing something?

        1. Take a raw 3.2 image
        2. DoIt:  "SqueakVersion setImage"
        3. Help -> updates

This loads a few updates, but then stops on or about update 4681.

Please advise where I am missing the boat, or what I should do to 
effect the update to current alpha using the updaters.
