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.
****************************************************************************
* New classes *
****************************************************************************
* New widgets
QHeader - Table header
QListView - Multicolun listview/treeview
QMainWindow - Application main window
QScrollView - Scrolling area (successor of QwViewPort)
QSpinBox - Spin button
QSplitter - Paned window
QStatusBar - Status bar
QToolBar - Container for tool buttons (and other widgets)
QToolButton - Fancy push button with auto-raise
QWhatsThis - Light weight help system
QWidgetStack - Stack of widgets
* Support classes
QFileIconProvider - Provides icons for the file dialog
QIconSet - Set of icons for different states
QListViewItem - Content of a QListView
QCheckListItem - Checkable list view item
* Drag and drop related classes

The file and print dialogs are far better.
Layouts will now automatically readjust if child widgets change
maximum/minimum sizes, or are deleted.
QFont now supports KOI8R
The reference documentation of the extensions is now integrated with
the main reference documentation in the qt/html directory.
****************************************************************************
* Changes that might affect runtime behavior *
****************************************************************************
None known.
****************************************************************************
* Changes that might generate compile errors *
