I've been gone a while and reading through the newsgroups and
knowledgebase has got me somewhat confused.

ZCM 10.0.1 is the downloadable version now.
Installed versions should get the update through the internal mechanism,
but it appears to be turned off for the moment.

So, is it turned off because the update mechanism is not good enough or
because the updates are bad for the system ?

And what bugs are addressed by the updates ? I have looked for a TID
about it and come up with nothing, nothing in the documetation either.
