Today, April 17th 2018, is an important day on the Fedora 28
schedule , with significant cut-offs.
Today we have the Final Freeze . This means that only packages
which fix accepted blocker or freeze exception bugs  will be
marked as 'stable' and included in the Final composes. Other builds
will remain in updates-testing until the Final release is approved, at
which point the Final freeze is lifted and packages can move to the
'updates' repository, pending updates will be pushed before final
release as zero day updates.
