Upgrading from pre-release to final
Fedora 21 Earlybird FAQ
Can I update the Fedora 21 Alpha/Beta/Snap#/Preview release to the final Fedora 21 release?
Yes. A few days before F21 is finally released, at 10am EST, there will be an updated "fedora-release" package which will change your release name from Rawhide to the final Fedora 21 (TBA), and more importantly, change your package repositories from rawhide to stable.
I found a Fedora 21 ISO leak before release day! Is it legit or is it exploited?
The only way to know for sure is to verify the leaked SHA1SUM's GPG signature (if available) with the official Fedora GPG key. If you can't, or won't do this, it's safer to just be patient and wait for release day. Also note that even if the early leak does check out, it might not be the FINAL release. Fedora has in the past had to re-push last-minute changes to the official releases.
I avoided Fedora 9 because there was no proprietary ATI display driver available. Is this fixed?
No. Please contact ATI. There's nothing Fedora can do about ATI not updating it's proprietary driver. Fedora 9 originally was released with a pre-release version of Xorg Server 1.4.99 . However the ABI (Application Binary Interface) has remained fixed after that and Fedora 9 includes the current latest Xorg 1.5 release in an update without any ABI changes. We recommend users try the latest open source ATI driver or use Intel or other cards which do not require proprietary drivers.
If I report my problem to fedora-test list or post in fedora forum, will my issues reach the developers?
You can use such avenues for discussions however for maximum efficiency, we always recommend that all actual bugs be reported to http://bugzilla.redhat.com against the appropriate package in rawhide. This is the only assured way of reaching the right developers.

Should I upgrade to Fedora 21?
We offer you the choice of the greatest and latest release. Per the Fedora lifecyle policy, each release of Fedora is maintained until a month after the second following release. For example, Fedora 8 will stop getting updates a month after Fedora 10 release. We highly recommend that users of unmaintained, "end-of-life" (EOL) releases upgrade to a newer release to continue getting critical security fixes.
