Qt 4.3.4 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 4.3.0 through Qt 4.3.3.
 
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.

    * This version adds the GNU General Public License (GPL) version 3
      to all Qt Open Source editions. The GPL Exception version 1.2

Build System
------------
    * Ensure that Qt plugin paths are only added once to the LIBS variable.
    * MinGW: Ensure that PRE_TARGETDEPS and POST_TARGETDEPS are properly
      escaped in dependency lists, so they match the rules in the Makefiles.
