Revision control
++ Qt 4.3.1 is a bug-fix release. It maintains both forward and backward
++ compatibility (source and binary) with Qt 4.3.0.
++
++ 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.

++ General Improvements
++ --------------------
++
++ - Translations
++ * Updated the German translation to provide complete coverage of Qt.
++
++ - QDBusView
++ * Added icons for Mac OS X and Windows.

++ on 64-bit hosts.
++
++ Third party components
++ ----------------------
++
++ - FreeType
