KDE is pretty much self contained, whereas a Qt upgrade affects a much
larger number of packages. I don't think updating Qt to a new major
version in a stable Fedora release is a good idea; it just causes too
much churn.

I am sure there will be bugs in other packages which need to be fixed to
work with Qt 4.7. Some of these bugs are going to be fixed in next
upstream releases, so people would just need to upgrade their packages
and build for F13. Other packages are going to work fine, but fail to
rebuild against Qt 4.7 if someone tries (consider security updates: a
build which starts suddenly failing when you need to get a two-line
security fix quickly out is not so fun).

I personally would not call it a stable release any more: a release
where lots of the apps need to be rebuilt, and lots of other apps need
to go through integration testing again is not a stable release. It's a
rolling development release.

In my opinion a Qt 4.7 update is pure F-14 material. As you say, it is
working pretty well on Fedora 14 which is going to be released very
soon, so why is there need for Qt 4.7 on F-13?

Thanks for all the nice work on Fedora 14 by the way!
