-All (GUI):
+- wxArray<T> macros have been changed to fix runtime problems under 64 bit
+  architectures and as a side effect of this WX_DEFINE_ARRAY() can only be
+  used now for the pointer types, WX_DEFINE_ARRAY_INT should be used for the
+  arrays containing non-pointers.

 
 

-- wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
+- wxObject::CopyObject() and Clone() methods were removed because they
+  simply don't make sense for all objects

 
 

-- wxGridCellAttrProvider class API changed, you will need to update your code
-  if you derived any classes from it
+- wxEvent now has a pure virtual Clone() method which must be implemented
+  by all derived classes, if you have user-defined event classes please
+  add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
+
+- wxCondition now must be used with a mutex, please read the (updated) class
+  documentation for details and revise your code accordingly: this change was
+  unfortunately needed as the old class didn't behave correctly in all cases
+
+- small change to wxStopWatch::Pause() semantics, please see the documentation
+
+- unlikely but possible incompatibility: the definition of TRUE has changed
+  from "1" to "(bool)1" (and the same thing for FALSE), so the code which
+  could be erroneously compiled previously such as doing "return FALSE" from
+  a function returning a pointer would stop compiling now (but this change
+  is not supposed to have any effects on valid code)

+All (GUI):

 
 - 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

+- wxDialog does not derive from wxPanel any longer - if you were using it in
+  your code, please update it. The quick fix for the most cases is to replace
+  the occurences of wxPanel with wxWindow.
+
+- 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 )

+- wxImage::ComputeHistogram()'s signature changed to 
+  unsigned long ComputeHistogram(wxImageHistogram&) const
+
+- wxEvtHandler cannot be copied/assigned any longer - this never worked but
+  now it results in compile-time error instead of run-time crashes
+
+- WXK_NUMLOCK and WXK_SCROLL keys no longer result in EVT_CHAR() events,
+  they only generate EVT_KEY_DOWN/UP() ones
+
+- the dialogs use wxApp::GetTopWindow() as the parent implicitly if the
+  parent specified is NULL, use wxDIALOG_NO_PARENT style to prevent this
+  from happening
+

 wxMSW:
