With the recent release of Fedora 24, Fedora 22 will officially enter End Of Life (EOL) status on July 19th, 2016. After July 19th, all packages in the Fedora 22 repositories will no longer receive security, bugfix, or enhancement updates, and no new packages will be added to the Fedora 22 collection.

Upgrading to Fedora 23 or Fedora 24 before July 19th 2016 is highly recommended for all users still running Fedora 22.

Looking back at Fedora 22

Fedora 22 was released in May 2015, and one of the more notable changes at release time was that yum was replaced by dnf as the default package manager in Fedora.

About the Fedora Release Cycle

The Fedora Project provides updates for a particular release up until a month after the second subsequent version of Fedora is released. For example, updates for Fedora 23 will continue until one month after the release of Fedora 25, and Fedora 24 will continue to be supported up until one month after the release of Fedora 26.

The Fedora Project wiki contains more detailed information about the entire Fedora Release Life Cycle, from development to release, and the post-release support period.
