The Fedora Project officially released Fedora 8 today, and the neatest feature is not this animated GIF! You can find a list of the many new features on the Fedora Project Wiki.
Let me take the opportunity to remind you that Fedora represents the cutting-edge in Red Hat-based Linux. Designed around a 6 month release cycle, it's most appropriate for desktops and other short-lived environments. Users seeking server-grade alternatives should investigate Red Hat Enterprise Linux or one of it's clones (CentOS, for example).
Finally, the release of Fedora 8 portends the end of life for Fedora Core 6.
