+All the Window and GDI (pen, bitmap, etc.) class constructors and also
+many toplevel functions and static methods will now check that a
+wx.App object has already been created and will raise a
+wx.PyNoAppError exception if not.
+
+Added more default args as needed to allow most window types to be
+constructed with only the parent window arg. In some cases other args
+may be required for normal operation, but they can usually be set
+after construction.
+
+Removed the deprecated ErrorDialogs and PythonBitmaps modules. If you
+were using these in your apps then please join wxPython-dev and assist
+with a more modern reimplementation.
+
+Added a new version (0.8.3) of FloatCanvas from Chris Barker. It's now
+in a subpackage of wx.lib.
