Fedora 8 Released
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.'"
RHEL 5.1 (if you mean this as one of two related distros) is a RHEL 5 re-packed to include all bug/security fixes to date, so if you need to do a new install, there's no need to pull hundreds of updates from RHN.
Fedora 8 isn't related too much to RHEL (RHEL 5 was built on Fedora Core 6). I use only Fedora and Red Hat and I'm probably biased. However, F8 includes some neat stuff that warrants checking up by Linux users in general. It works great, too.
Red Hat pays many of their developers / admins to work full time or part time on the Fedora project. They have a vested interest after all -- much of Fedora eventually makes its way into RHEL.

Red Hat Magazine posted a HOWTO explaining Fedora 8 booting from a USB key.
It is one of the more interesting features in Fedora -- users can build their own customized spin of the distro, and then run it on a USB key. Totally custom and portable.
PulseAudio emulates all the other systems with LD_PRELOAD libs so that they are all PulseAudio-aware. This means that your 1998 softphone that uses exclusive open() on /dev/dsp will function, with the magical policy of PulseAudio.
æeee!
Incidentally, PulseAudio is PolypAudio.
The new system is replacing userhelper, so there will be the same number of (or likely fewer) password popup prompts - not more. See the wiki (google cache) for details.
