+INCOMPATIBLE CHANGES SINCE 2.2.x
+================================
+
+All (GUI):
+
+- wxGridCellAttrProvider class API changed, you will need to update your code
+ if you derived any classes from it
+
+wxMSW:
+
+- 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!
+
+- child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
+ style to avoid it, wxFRAME_FLOAT_ON_PARENT style is now obsolete and has no
+ effect
+
+2.3.2
