I am sure you have heard by now about the KDE 4.0.0 release made yesterday. Currently my desktop machine is on a boat in the middle of the Atlantic somewhere, my laptop is broken and I only have access to Apple systems... I was able to check out KDE 4 and test it in a VM and it is looking good.
I haven't been able to help with Gentoo packaging of KDE 4 very much at all which is a shame. I should get my desktop back at the end of the month in my new home in Pittsburgh. I also couldn't attend the release event as I am attending my graduation ceremony on the 17th of January. Hope you guys really enjoy the event and if I could have moved things around to attend I certainly would have.
There is lots of stuff I hope to be able to do for KDE 4.1, and more specifically Kalzium, once I get my desktop back at the end of the month. Avogadro already has lots of improvements including a KGraphicsView based periodic table which I think Carsten is interested in me getting into Kalzium 4.1.
Enjoy the release event and remember to raise a glass to those of us unable to make it for various reasons 
Either decide to move on to Avo 1.0 and then make Kalzium use it
or port Kalzium to use Avo 0.3 and hope not to much breaks in 1.0
