+****************************************************************************
+
+ - When running Qt/DirectFB the DirectFB window id of a top level QWidget can
+ be queried using property("_q_DirectFBWindowID")
+
+ - Allow setting the background color of the primary layer in DirectFB with
+ connect options. QWS_DISPLAY=directfb:bgcolor=red or
+ QWS_DISPLAY=directfb:bgcolor=\#aabbccdd
+
+ - Add support for rendering mouse cursor using a top level window when cursor
+ support is not working in IDirectFBDisplayLayer. Define
+ QT_DIRECTFB_WINDOW_AS_CURSOR to enable.
+
+ - Add experimental support for optimized locking/unlocking of surfaces. Enable
+ by defining QT_DIRECTFB_SUBSURFACE.
+
+ - Fix a bug to conceptually allow using QDirectFBScreen as a subscreen of a
+ proxy screen. Don't make QDirectFBScreen::instance() assume that
+ QScreen::instance() is a QDirectFBScreen.
+
+ - Optimize move/resize operations with DirectFB. With a properly configured
+ DirectFB these operations are handled for us and we don't need to force a
+ repaint of the window.
+
+ - Support top level window opacity in DirectFB
+
+ - Fix a bug when loading RGB32 images that would lead to rendering issues.
+
+ - Fix a bug when painting with invalid pens/brushes.
+
+ - Fix a bug that would show up when QWidget::scroll is called.
+
+ - Implement support for loading pixmaps using IDirectFBImageProvider.
+
+ - Disable color table support by default. This seems to work incorrectly on
+ most boards and loading these images will generally require an image
+ conversion anyway.
+
+ - Fix a bug regarding QGraphicsProxyWidgets
+
+ - Fix a crash when resizing windows
+
+ - Compile with versions < 1.0. We still recommend using newer versions.
+
+ - Considerable code cleanup
+
+ - Various optimizations regarding painting, loading of images and creation of
+ surfaces.
+
+ - Allow forcibly falling back to raster engine for painting operations by
+ exporting QT_DIRECTFB_FORCE_RASTER=1
+
+ - Reenable support for RGB32 primary surface.
