The Fedora 20 "Heisenbug" alpha release has arrived with a preview of the latest fantastic, free, and open source technology currently under development. Take a peek inside from your closest mirror:

What is the Alpha Release?

The Alpha release contains all the exciting features of Fedora 20 in a form that anyone can help test. This testing, guided by the Fedora QA team, helps us target and identify bugs. When these bugs are fixed, we make a Beta release available. A Beta release is code-complete and bears a very strong resemblance to the third and final release. The final release of Fedora 20 is expected in early December.

We need your help to make Fedora 20 the best release yet, so please take some time to download and try out the Alpha and make sure the things that are important to you are working. If you find a bug, please report it – every bug you uncover is a chance to improve the experience for millions of Fedora users worldwide. Together, we can make Fedora a rock-solid distribution. We have a culture of coordinating new features and pushing fixes upstream as much as feasible and your feedback will help improve not only Fedora but Linux and free software on the whole. (See the end of this announcement for more information on how to help.)
