I got a bunch of emails in the last weeks with one or more of the following questions. Here it is for general knowledge :)
Will be KDE 4.2 beta 1 uploaded to experimental? Or to another public repository?
And KDE 4.2 beta 2?
Maybe. But notice if it is uploaded it will be replacing current KDE 4.1 in experimental, so we will upload it only if we are sure it is stable and mature enough to replace 4.1
Will be KDE 4.2 backports in http://kde4.debian.net ?
No, backports were planned only for the KDE 4.1 series.
If experimental starts shipping KDE 4.2 (beta or RC), will be updates in http://kde4.debian.net for 4.1.4 (and if released 4.1.5)?
Yes, there will be backports for all the releases of 4.1.x.
When will be KDE 4 uploaded to unstable? And to testing?
KDE 4 will replace KDE 3 in unstable when Lenny is released. After some time, it will migrate from unstable to testing.
Bonus question: When will be Lenny released?
When it is ready.
