The Fedora 19 Alpha has been delayed by one week, thus pushing back all other milestones for this next version of Fedora Linux. The Fedora 19 Alpha delay is coming due to unresolved UEFI bugs blocking the release.
The next target is for pushing out the alpha on 23 April, the beta on 28 May, and the final release already on 2 July. That's assuming things work out, but it would be incredibly surprising if this is the only delay this release cycle. On the Fedora Project Wiki is the F19 release schedule.
When it does arrive, at least there's a large number of new features.
The Fedora 19 Alpha delay was announced on Thursday on the devel-announce list for Fedora developers.
