Top problem is QtWebKit - it's practically impossible to backport security issues and as everybody knows - WebKit is security issue itself... It's really time consuming task. We hoped we can get standalone QtWebKit by F14/Qt 4.7 but upstream is unable to allocate enough resources to support it now. We're even considering possibility to split QtWebKit from main Qt package and build it over the older Qt releases but don't like this idea - it probably will bring much more issues than fix (older Qt releases should be supported but no-one tests it probably, so problems can't be avoided here). For Qt itself - once QtWebKit will be separated, need for update would go to zero... As the most work is done now on mobile devices support. Only one interesting feature for Fedora users has been completed - Qt Quick - it opens a lot of new possibilities for rich desktop application development and I think it should be path for Fedora too (ala for installer, firstboot, some welcome screen etc.). So with WebKit SIG hat - newer QtWebKit is the must now.
