"Another good addition for Fedora 9 is called PackageKit and works as a universal frontend for package management. Some features introduced with Fedora 8, such as the PulseAudio sound server and the PolicyKit secure privilege escalation system, have returned in a better integrated and a more complete way. Also, the Nodoka theme, appears cleaner and feels more polished."
