Catchy intro here.
What is the Beta Release?
The beta release is the last important milestone of Fedora 14. Only critical bug fixes will be pushed as updates leading up to the general release of Fedora 14, scheduled to be released in early November. We invite you to join us and participate in making Fedora 14 a solid release by downloading, testing, and providing your valuable feedback.
Of course, this is a beta release, some problems may still be lurking. A list of the problems we already know about is found at the Common F14 bugs page.
If you find a bug that's not found on that page, be sure it gets fixed before release by reporting your discovery at https://bugzilla.redhat.com/. Thank you!
