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. Shortly 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. A layman's version of the specific details is available.
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.
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 the Fedora bug tracker (Bugzilla) against the appropriate package in rawhide. This is the only assured way of reaching the right developers.
When is Fedora 21 going to be released?
An up-to-date release schedule is always maintained at Releases/21/Schedule.
What are the new features in Fedora 21?
The Fedora 21 feature list has more details.
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 19 will stop getting updates a month after Fedora 21 release. We highly recommend that users of unmaintained, "end-of-life" (EOL) releases upgrade to a newer release to continue getting critical security fixes.
How can I upgrade?
Refer to Upgrading.
