Qt 4.2.2 is a bug-fix release. It maintains both forward and backward+
−
compatibility (source and binary) with Qt 4.2.0.+
−
+
−
The Qt version 4.2 series is binary compatible with the 4.1.x and 4.0.x+
−
series. Applications compiled for 4.0 or 4.1 will continue to run with 4.2.+

----------------------+
−
+
−
- libpng+
−
+
−
  * Security fix (CVE-2006-5793): The sPLT chunk handling code+

−
    items.+

−
    from a QAbstractItemView in editing mode.+
−
+
−
  * Date and time editors are now initialized correctly with the current+
−
    date and time.+
−
+
−

−
    model).+
−
+
−
  * Fixed bug in QItemDelegate that would scale decoration pixmaps.+

−
  * Fixed a crash when selecting one selectable item, then moving another+

+
−
  * Avoid rounding errors when drawing parts of a pixmap using the Quartz 2D+
−
    engine.+
−
+
−
  * Added caching of QGradient's color table for the raster paint engine.+
−
    This means that if a gradient with the same stops and colors is used+
−
    again, it will be quickly fetched from the cache, avoiding the+
−
    expensive calculations of the color lookup table.+
−
+
−
  * Fixed a crash on Windows and with QImage caused by specifying+
−

−
    QImage did not have any effect.+
−
+
−
  * Fixed bug in QImage::createHeuristicMask where the color table was not +
−
    initialized properly.+
