It is certainly not BC forwards (backwards?), unless you happen to not 
be using anything from the new version when you change to an old version 
(and even then, I would consider that a bit "lucky"). Stuff built for 
old should generally run on new, however. Where by "generally" I mean 
"except for version changes that are specifically not BC, usually major 
version changes only".

Having said that, I will note that I, personally, always rebuild the 
(KDE) world when qt-copy has a major update.
