KDE follows a 6 months cycle release.
Qt 4.6 should be released by the end of 2009 or early 2010.
imho, some people will try to push KDE 4.4 dependency on Qt 4.6.
for Debian stable, I think releasing with Qt 4.6.0/KDE 4.4.0 is a very bad idea.
bugfix/patch release is preferred and according to the timeline, it
will be Qt 4.5.x/ KDE 4.3.x.
basically, we have have the materials (Qt 4.5.2/KDE 4.3.0 and soon KDE
4.3.1). Now, we should fix bugs...
In summary: I agree with Ana's comments.
