Cool: my Ubuntu 5.04 box needed a new upgrade. Remember I'm also running Mandriva 10.2 on another one (sometimes I feel like a complete nerd.). From their site:
Fedora Core 4 is now available from Red Hat and at distinguished mirror sites near you, and is also available in the torrent. Fedora Core is available for x86-64, i386, and ppc/ppc64. Please file bugs via Bugzilla, Product Fedora Core, Version 4, so that they are noticed and appropriately classified. Discuss this release on fedora-list.
OSNews has an early review. Redhat Magazine has a lenghty description.
