Fedora 27 will be the distribution's first release not doing any alpha milestones. Instead, the distribution is trying to focus on better daily quality of Fedora Rawhide / F27, similar to Ubuntu not doing alpha/beta releases and openSUSE Leap also deciding to go a similar route.
The elimination of alpha releases from the Fedora 27 schedule were approved at today's Fedora Engineering and Steering Committee meeting, via the FESCo minutes.
Fedora 26 meanwhile is still going ahead with its alpha release that will be available soon. Hopefully for Fedora 27 they will still manage to deliver great and reliable quality and possibly be the first release in quite a while to manage it out on time.
