  - KDE Integration: Improved the integration into KDE desktop (loading of KDE

+ - Fixed pasting the clipboard content to non-Qt application on X11 when the
+   requested format is image/ppm. Patch by Ritt.K
+
+ - On Windows when a file cannot be accessed (stat()ed), we are now restoring
+   the error mode to the original value.
+
+ - 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

+
+ - Add support for GetURL events on Mac OS X
+ 
+General changes on Mac OS X:
+ - Mac OS X version support: Support for 10.3(Panther) has been dropped, support for
+   10.6(Snow Leopard) has been added.
+ - The Cocoa port now supports static linking.
+ - The Cocoa port now supports the Qt3Support library (with the exception of Q3FileDialog)
+   to ease the transition from Carbon to Cocoa.
+ - The Cocoa binary packages are now Intel only (universal i386 and x86_64).
+ - Snow Leopard notes:
+    - Gcc 4.2 is used by default. Configure with -platform macx-g++40 to select 4.0.
+    - Using the 10.4u SDK requires gcc 4.0.
+    - Configuring for the Cocoa port (-cocoa) produces 64-bit binaries by default.
+      Use the -arch flags to override.
+    - Building for ppc64 is no longer supported by the gcc tool chain.
+    - Building for ppc is still supported.
    
  - Phonon on Windows
    * Now much more reliable when reading a file through a QIODevice.
