Does Parallels 8 support Mavericks and Windows 8.1?

The question is really in the title. I currently run Parallels 8, with OS X 10.8 + Windows 8, and I'm planning on upgrading to OS X 10.9 + Windows 8.1 once both of those updates become available. Will I be able to do each of those upgrades while staying at Parallels 8, or will I have to upgrade to Parallels 9?

Thanks for your help! I've looked around quite a bit but couldn't find a definitive answer anywhere. :)
