About the Fedora Release Cycle
The Fedora Project provides updates for a particular release until a month after the second subsequent version of Fedora is released. For example, updates for Fedora 25 continue until one month after the release of Fedora 27. Fedora 26 continues to be supported up until one month after the release of Fedora 28.
The Fedora Project wiki contains more detailed information about the entire Fedora Release Life Cycle. The lifecycle includes milestones from development to release, and the post-release support period.
