Cat in the Hat writes: Fedora 8 has been officially released. Ars Technica has a run-down of what's new in Fedora 8, including the PulseAudio sound daemon, Nodoka visual style, and a new authentication system. 'Another major change in Fedora 8 is the new PolicyKit authentication system that makes authority escalation more secure. Instead of providing root access to an entire program when it needs higher privileges, PolicyKit makes it possible to isolate individual operations that require higher privileges and put them into system services that can be accessed through D-Bus. Another advantage of PolicyKit is that it will give administrators more control over which users and programs have access to individual operations that use escalated privileges.'
