New Firefox vs. Up2date

[Jonathan Ryshpan <jonrysh pacbell net>]

The Red Hat Network Notification Tool (KDE Applet) tells me correctly
that there is a new version of Firefox available.  The version on the
nachine is firefox-1.0-2.fc3.x86_64.rpm, while the latest version on the
server is firefox-1.0.1-1.3.1.x86_64.rpm.  Nevertheless, up2date doesn't
report the new version as available for installation.

Does anyone know why this is?  Is the new firefox worth hand
installation?
