6.4 With KDE .iso

I've been thinking of moving back to Fedora for a bit, specifically the KDE version, I'm currently I'm using Workstation. Although, just using the live iso, it's still on 6.3. Is there a way to update it to 6.4 or will I have to download KDE on top of Gnome? If so then it's fine, just a little inconvenient. I apologize if this is a common question.
