The only release to land on an odd day of the month has been Fedora Core 4 Stentz, which came on June 13, 2005. Introduced in Stentz was the Clearlooks theme by default (replacing Bluecurve) as well as integrated Xen support. Shipping with Fedora Core 4 was a pre-release of OpenOffice.org 2.0, GNOME 2.10, and Eclipse with gcj. Two important milestones were Fedora Extras being available at release time and PowerPC architecture support. Up to the time of Stentz, only x86 and x86_64 versions of Fedora Core were made available.
