Whoops! I didn't notice that 5.0.7 had been released already!
I'm looking to upgrade our Zimbra server from 4.5.6 to the latest 5.0 version. I have been avoiding this to allow 5.0 bugs to get squashed and because there are a number of manual changes involved with the upgrade. Before I go and upgrade to 5.0.6, is there a timeline for when a 5.0.7 release is anticipated?
