I am a 3.0 user and do not want to upgrade until Ubuntu is supported (8.10). will there be some kind of official announcement when Parallels can do thiis, or wil I have to skim the forums? Or, is Parallels not planning to support Ubuntu till 5.0? Thanks!
Go to http://www.parallels.com/download/desktop/ every now and then and check "Parallels Desktop 4.0 for Mac Read Me and Release Notes" to see if it´s one of the supported guest OS.
Let me clarify,
From build to build we are adding as much possible OSes and features,
And documentation is a bit conservative, and we are trying to keep it touch,
We will update documentation soon
