   - Extended window style wxPG_EX_LEGACY_VALIDATORS was removed.
 
+  - Default property validation failure behavior has been changed to
+    (wxPG_VFB_MARK_CELL | wxPG_VFB_SHOW_MESSAGEBOX), which means that the
+    cell is marked red and wxMessageBox is shown. This is more user-friendly
+    than the old behavior, which simply beeped and prevented leaving the

   - wxPropertyGridManager now has same Get/SetSelection() semantics as
     wxPropertyGrid.
