Today KDEPIM 4.6 Beta3 is tagged and released.
This is the first release in our departure from the normal KDE SC 4.6 cycle,
Note that it does require the 1.4.90 Akonadi server which was just released yesterday.
Once the mirrors catch-up you should find the source code in ftp://ftp.kde.org/pub/kde/unstable/kdepim.
We'll re-evaluate our progress (based on your constructive feedback) in a week or so and decide on our next release -- on our way to KDEPIM 4.6.
