+Here is a list of user-visible changes in Qt from 1.33 to 1.40.
+
+Qt 1.40 supports drag and drop, with a simple, platform independent
+API. There are eleven new widget classes in 1.40. Asynchronous I/O
+support is now in the official Qt API.
+
+Since Qt no longer supports any platforms that only supports 8.3
+format file names, the file names of the Qt source and include files
+have been made simpler. #include <qcombobox.h> instead of qcombo.h,
+etc. The old names are still present for compatibility.
+
+The new Qt Xt/Motif Extension allows Qt widgets and applications to
+coexist with old Xt/Motif-based applications and widgets.
+
+There are more than one hundred new functions added to existing
+classes and, as usual, we fixed some bugs, made some more speedups,
+and improved the documentation.
+
