'The Fedora Project is a Red-Hat-sponsored and community-supported open source project. It is also a proving ground for new technology that may eventually make its way into Red Hat products. It is not a supported product of Red Hat, Inc.'.
In short, Red Hat has decided to focus strongly on the Enterprise market (follow the money, there is nothing wrong with that) and as a result has discontinued marketing or producing new versions of what many considered to be its 'home user' freely downloadable versions of Linux, but all is not lost, not by a long shot. Red Hat has not abandoned the home users (or free OS down-loaders like me), not at all, it is providing some of its expertise in OS development, tools and financial sponsorship to the Fedora Project (http://fedora.redhat.com).
