“Among the new features in Bugzilla 3.0, according to
Kanat-Alexander, include mod_perl extension support, which means
Bugzilla page loads can occur up to six times faster than before.
Custom fields support allows privileged users to add plain text or
drop-down custom fields in their Bugzilla installs in addition to
the default fields Bugzilla ships with.”
