Beginning with Fedora 27 we could see no more alpha releases, if the Fedora Engineering and Steering Committee approves of this change. The focus would be on ensuring Fedora Rawhide is always in good shape and save on release engineering time and other resources with putting out alpha builds.
This could also be of help in potentially getting a Fedora release out on time, a feat not accomplished in a number of cycles now.
For those interested the NoMoreAlpha Wiki page documents the planned change for Fedora 27. "By gating Rawhide builds from landing in the compose and gating the publication of composes on automated test results we will ensure Rawhide will always be at Alpha quality. This will make it more generally useful to people as a daily driver and development platform, and mean we no longer need to go through the process of building, testing and shipping Alpha releases. The initial testing will be ensuring that a package is installable and that it does not break existing packages installation. Over time we can enable extra testing to gate the build going into rawhide. Builds will land in the buildroot to be built against before they make it to the compose."
