[Mailman-Developers] pipermail feature request for View by Date

Hi all, I am new member of this list and using Fedora mailing lists. Previously Fedora project mailing lists allows "view by Date" archive option as can be seen at https://www.redhat.com/archives/fedora-devel-list/2010-January/date.html but now they migrated to new interface http://lists.fedoraproject.org/pipermail/devel/2010-January/date.html and this does not show threads by Date. Can someone knows if there is any good reason for not to have this implemented yet?

Thanks & Regards, Parag.
