Qt Installer Framework Versions ... which should I use ?

[SCrash]

Hello,
I try to find out, which version of the Qt IFW I should use.
I want to build the Framework from source. I want to use a stable version, but there are several versions (1.5, 1.6 and 2.0).
Which of them is stable enough to use ?
