No.  I took some notes which I'll stick in a blog entry later today. 
This is what I wrote down...

1. Manually upgrade the fedora-release and fedora-release-notes
    packages like so:

rpm -hUv \
http://mirrors.cat.pdx.edu/fedora/linux/releases/test/7.92/Fedora/i386/os/Packages/fedora-release-7.92-1.noarch.rpm 
\
http://mirrors.cat.pdx.edu/fedora/linux/releases/test/7.92/Fedora/i386/os/Packages/fedora-release-notes-7.92-2.noarch.rpm

2. Disable all third-party repositories in /etc/yum.repos.d.

3. Remove third-party packages for which there is no new repo.  The
    upgrade fail due to broken dependencies otherwise.

4. "yum update"

5. Now your system has updated versions of all of your previously
    installed packages.  In order to pick up new packages from the
    groups you care about, you'll want to do something like so:

yum groupinstall "GNOME Desktop Environment" "Development Tools" \
  "Server Configuration Tools" "Hardware Support" \
  "Sound and Video" "Graphical Internet" "Fonts" \
  "Games and Entertainment" "Printing Software" \
  "Administration Tools" "Office/Productivity" "System Tools"

6. Cross fingers & reboot.

I'm going to file a bug against the Fedora qjackctl today.

It seems to, yes.  F8 is pretty nice!

Ok, good to know.  This will be in my bug report as well.
