****************************************************************************
* Platform Specific Changes *
****************************************************************************
+ - Added support for the Symbian platform with integration for the S60
+ framework.
+
+ - Added community supported Qt ports for QNX and VxWorks. See platform
+ notes in the Qt documentation for details.
+
+ - Improved support for AIX using IBM's Visual Age C/C++ compiler
+ version 7 (xlC).
+
+ - Improved support for Solaris using Sun Studio 12 (CC 5.9).
+
+Qt for Unix (X11 and Mac OS X)
+------------------------------
+
+ - Added support for thread-safe FD_CLOEXEC file-descriptor creation
+ where supported by the operating system (currently only Linux).
+
+ - Ensured that system calls where EINTR is a possible result are
+ properly restarted.
+
+Qt for Linux/X11
+----------------
+
+ - KDE Integration: Improved the integration into KDE desktop (loading of KDE
+ palette, usage of KColorDialog and KFileDialog) using the GuiPlatformPlugin
+
+ - Fixed pasting the clipboard content to non-Qt application on X11 when the
+ requested format is image/ppm.
+
+ - On X11, Qt now supports the _NET_WM_SYNC protocol.
+
+ - On X11, Qt now supports the SAVE_TARGET protocol that allows to keep
+ clipboard contents if the application that owns the clipboards exits
+
+ - [QTBUG-4652] On X11, clipboard content can be properly retrieved even when
+ an application asks for the unsupported target. This fixes copying and
+ pasting data when using Synergy.
+
+ - [MR#797] Fixed a crash when using QX11EmbedContainer/Widget on x86_64.
+
+ - [MR#1111] Emit workAreaResized when _NET_WORKAREA is changed on X11.

+ it was unreadable when printed or presented in a print preview widget.
+
+ - Improved EGL integration on X11 (including better visual selection).
+
+ - Made Qt::WA_TranslucentBackground work in combination with native
+ child widgets.
+
+ - Support Qt::WA_TranslucentBackground on top-level QGLWidgets on X11, both
+ (EGL & glX). This allows OpenGL (& ES) rendering to semi-transparent widgets
+ if a compositing window manager is running.
+
+ - Support OpenGL texture_from_pixmap extension on X11 (EGL & glX) when
+ calling QPainter::drawPixmap() with the OpenGL paint engine, or calling

+
+ - Add new experimental QX11GLPixmapData backend for QPixmap. This pixmap

+ OpenGL to render into them.

+ - Tablet: Disable event compression of events of type QTabletEvent when the
+ current event is accepted by the receiver.
+
+ - [QTBUG-4242] Fixed a bug that allowed the user to close a window

+ - [255559] Fixed generation of XdndLeave events to include the correct
+ source id.
+
+ - [258319] Avoid division by zero on some Xlib/Xserver implementations.
+
+ - Fixed the default QWidget size on X servers with Xinerama to give widgets
+ a default size that should fit on a single screen.
+
+ - Support _NET_WORKAREA on X servers with Xinerama (previously this property
+ was ignored).

+
+ - 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

+ most boards and loading these images will generally require an image
+ conversion anyway.
+
+ - 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.
+
+

+
+ - On Windows CE the link time code generation has been disabled by default to
+ be consistent with win32-msvc200x.
+ - The default button size has been reduced in the Windows mobile style.
+ - [QTBUG-3613] QWizard issues have been fixed on Windows mobile.
+ - [254673] Restoring minimized widgets fixed for Windows mobile and
+ Windows CE.
+ - [255242] Seeking within large files (bigger than 0x80000000 bytes) fixed
