How to Try Alpha

  • Boot it!
  • Run it!
  • Test it!
  • Write bugs!

Verify Fedora

Fedora does not publish MD5 or SHA1 hashes to verify images since they are not secure enough. Instead we have been using SHA256 since Fedora 11. In Linux, you can use sha256sum command (part of coreutils and installed by default) to verify the Fedora image

sha256sum -c *-CHECKSUM

Windows can use the free to download utility HashCalc.

Mac OS X can use the free to download utility hashtab.

Fedora GPG signatures can be verified following the instructions here

Debugging Information And Performance

Fedora kernels have many extensive debugging options during the developmental cycle that have a negative impact on performance but provide developers with more information automatically, in the case of bug reports. If you are running performance analysis on Rawhide or test releases such as Alpha or Beta, make sure you take this into account.

Fedora 18 Release Schedule And Feature Details

Development continues on Rawhide during and after this release, leading to the beta, then the final release. The links below provide the release schedule for both the pre-releases and the final release, as well as the wiki's pages for tracking the various features planned for inclusion in Fedora 18.
