Q. Which platforms are deprecated with the release of Zimbra 8?
A. With the release of Zimbra 8, Zimbra no longer supports Ubuntu
10.04 (64-bit). Refer to the VMware Zimbra Collaboration
Server 8 System Requirements Guide for the up-to-date list.
However, there is a download link for Ubuntu 10.04. Is this a misprint, or do I need to start testing a new platform?
