Fedora Core 4 was released on June 13, 2005, with the codename Stentz. It shipped with Linux 2.6.11, KDE 3.4 and GNOME 2.10. This version introduced the new Clearlooks theme, which was inspired by the Red Hat Bluecurve theme. It also shipped with the OpenOffice.org 2.0 office suite, as well as Xen, a high performance and secure open source virtualization framework. It also introduced support for the PowerPC CPU architecture, and over 80 new policies for SELinux.

None of these distributions are maintained by the Fedora Project.[33]
