+- the event type constants are not constants any more but are dynamically
+ allocated during run-time which means that they can't be used as case labels
+ in the switch()es, you must rewrite them to use if()s instead
+
+ You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
+ but this is strongly discouraged, please consider changing your codei
+ instead!
+
+- wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
+ have changed (to fix some unfortunate clashes), please check your code to
+ ensure that no tests for wxYES or wxNO are broken: for example, the following
+ will *NOT* work any longer:
+
+ if ( flags & wxYES_NO )
+ ... do something ...
+ if ( flags & wxYES )
+ ... do something else ...
+
+- wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
