I have no idea if we have a document.

Basically, Qt 4 is a binary-compatible major series. Binary and source 
compatibility flows forwards across minor releases (i.e., if you compile with 
4.x, it'll run with 4.y provided y >= x). Binary and source compatibility are 
forwards and backwards withing the same minor series (if it compiles with Qt 
4.x.y, it compiles with Qt 4.x.z and will run with 4.x.z).
