OK, this is a notable one, so here's the scoop. :)
1. Obsoletes: knetworkmanager
2. enables the requisite networkmanagement kded module by default
3. includes a script to enable the the nm plasma applet in your systray
(on your next login).
This was done because:
1. upstream doesn't have much interested in the monolithic knm client
anymore (ie, no support, no bug fixes, yada yada)
2. knm doesn't work (well) with kde-4.5 anyway, see
for more details.
