As of the 19th of July 2016, Fedora 22 has reached its end of life for
updates and support. No further updates, including security updates,
will be available for Fedora 22. A previous reminder was sent on 22nd
of June [0]. Fedora 23 will continue to receive updates until
approximately one month after the release of Fedora 25. The
maintenance schedule of Fedora releases is documented on the Fedora
Project wiki [1]. The Fedora Project wiki also contains instructions
[2] on how to upgrade from a previous release of Fedora to a version
receiving updates.
