Qt 4.3.3 is a bug-fix release. It maintains both forward and backward

compatibility (source and binary) with Qt 4.3.0 through Qt 4.3.2.

The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and

4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to

run with Qt 4.3.
