It is strongly recommended that you verify the integrity of these packages by installing the archive’s GPG key. You may do this by following the instructions on this page.
This archive includes a new network manager application, run “knetworkmanager” (the Plasmoid is just a dummy currently).
Packages for Jaunty are not officially supported. KDE 4.3 will be part of Kubuntu Karmic 9.10 to be officially released this October.
