+Here is a list of user-visible changes in Qt from 1.1 to 1.2.  As
+usual, we fixed some bugs, made some more speedups, and improved the
+documentation.
+
+
+****************************************************************************
+*               Changes that might affect runtime behavior                 *
+****************************************************************************
+
+QGridLayout::addWidget() and addMultiCellWidget(): The align parameter
+is now interpreted correctly. (Previously up/down and right/left were
+reversed.) If you have worked around this bug, your widgets may now be
+incorrectly aligned.
+
+QWidget: Every widget is now guaranteed move and resize events. The
+event is deferred until the first show(). This may cause problems in
+rare cases involving event filters.
+
+****************************************************************************
+*               Changes that might generate compile errors                 *
+*                        when compiling old code                           *
+****************************************************************************
+
+none
+
+****************************************************************************
+*               Type changes that might generate warnings:                 *
+****************************************************************************
+
+none
+
+****************************************************************************
+* 			Deprecated functions				   *
+****************************************************************************
+
+QApplication::setColorMode() and colorMode() will be obsoleted. Use
+setColorSpec() and colorSpec() instead.
+
+qchecksum() will be obsoleted. Please use qChecksum() instead.
+
+****************************************************************************
+* 			     New classes				   *
+****************************************************************************
+
+QSlider is a widget to input values from a range. If you have been
+using a standalone QScrollBar, you will probably want to switch to a
+QSlider.
+
+OpenGL/Mesa support: QGLWidget, QGLContext and QGLFormat. To use these
+classes you need to build the Qt/OpenGL library (qgl) in qt/opengl/src.
+
+****************************************************************************
