Thanks @Conan-Kudo, tracking

@caldav Fedora 27's update is blocked on the Go/No-Go meeting for the beta. Since it's been delayed a week, all updates stay in updates-testing. That said, updates-testing is enabled by default on pre-release Fedora, so it's effectively available anyway.

@caldav The Fedora 27 update synchronized out to the stable repositories now.
