For all of you idling in #kde4-devel while celebrating the release: we closed down the channel in order to remerge it with #kde-devel, now that KDE 4.0 is out. So that is the reason why you got kicked by either me or dfaure :-). The channel is now a redirect if you try to join. If you feel insulted by the sudden kick: Sorry (well, from me, not sure how David feels about it ;-)).
But don’t worry, we rented a real party channel over at #kde4-release-party!
