As per Zimbra's normal updates, our upgrade procedure from 6.0.6 to 6.0.7 this morning was flawless. I downloaded lastnight and updated this morning in less than 20 minutes including the MySQL db check.

Thank to all the Zimbra crew for making this sort of routine update truly routine and nothing to note except for the fact that there is nothing to note. (Yes, I have been reading Dr Suess to my kids the last few nights.)
