qt3.x and binary compatability
by Jeremy Petzold on Tuesday 25/Sep/2001, @07:37

is it true that after the move to qt3.0 there will be no more binary breakage from 3-> 4-> x.y?

4.0 will break binary compatibility with 3.x. Many things can be done in a binary-compatible way, but over time the pressure builds and we really have to break binary compatibility. This is a non-issue with major releases since the linker ensures the right libraries are used (like libc5 and libc6 on your Linux machine).

Source compatibility is something else. The 1.x to 2.0 change broken a lot of code (but in easy-to-fix ways). The 2.x to 3.0 change will break very little code. So you can expect that between 3.x and 4.0, source compatibility will be even higher.

But hey, let's worry about 3.0 for now, not 4.0!!
