ViperHost is not too far away from upgrading . I downloaded MySQL 4.0 and went to install it, but errors ran amock, so I am waiting on CPanel to complete their build before we proceed any further.
It should not be long, a thread dedicated to it has been started, the usually follow on software updates, sadly, some of their features are lacking functionality.
This is not planned at this time. At some point in the future when we decide to make such an upgrade, we will be sure to post in the forums so that everyone is aware.
