Every time a new Fedora release is out, users receive notifications that a new version is available, and this time is no different. If you’re running Fedora 26 you might see a notification somewhere in the notification applet in the panel about the release of Fedora 27. If you didn’t receive any notification or you missed it, you can still upgrade by opening GNOME Software and accessing the Updates tab. Wait a few moments for the list of updates to refresh or click the Refresh button, and you should see the new Fedora release there.
