From fedora-release-notes-8.0.0-3, the most prominent feature (listed first): * This test release features GNOME 2.20. GNOME now includes mail notification in the Evolution mail client, the ability to fill in PDF forms in the Evince document viewer, improved file management, a revamped Appearance control panel applet, a revised help system, and many other enhancements. I surely hope F8 is not a test release but a real one!
Thanks for catching this. The fix should be in the zero-day update.
