the plan is to release 2 Kubuntu 8.04 CD´s: one with KDE 3.5.8 (or .9) as default, and one with KDE 4 as default (but of course with some KDE 3 apps)
I’m running KDE4 RC1 as my main desktop for 2 days now. Only few crashes, so productivity is good. But there are many small bugs. And it’s not very fast/responsive. But this is at least partially to blame on all the debug code.
Quite happy so far! It’s shaping up! Please test!!!
Please report any possibilities to try out KDE4 the easy way in the comments section:-)
