As of 6th of January 2014, Fedora 19 has reached its end of life for updates and support. No further updates, including security updates, will be available for Fedora 19. A previous reminder was sent on December 10th [0].
Fedora 20 will continue to receive updates until approximately one month after the release of Fedora 22. 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.
