Raw Blame History

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.
