No plasma notification's on KDE 4.4 Unstable

I have installed KDE 4.4 unstable KDE4:Unstable (Factory). When for example, Kopete shows a notification, it’s not a plasma notification, but an old style notification (not the plasma ones). In Ubuntu with KDE Neon installed, the notifications do work. Do the plasma notifications depend on some package I forgot to install or upgrade?

Plasma notifications disappeared from me too after updating a few weeks ago. They haven’t returned with the latest updates…

Not 100% sure on this but i do recall that the notifications were developed seperatly from plasma, this was for testing while they made a workable API. it was planned in 4.4 to merge it into plasma shell as final for all developers to have access, so maybe they need to move around some code to get these features working again.
