With any release-oriented distro(Fedora/Ubuntu/(Debian?)...), there is
feature freeze.
AFAIK, 2.6.25 might be the final kernel release for Fedora 9. You cannot
install any
newer version unless you build the kernel yourself. Similarly 2.6.27 is the
latest for
F10. 2.6.28/29 may find its way into F11.
The reason for the feature freeze is to start focussing more on bug fixes.
