 - wxNotebookSizer and wxBookCtrlSizer are now deprecated -- they are no longer
   needed, you can treat wxNotebook as any other control and put it directly
   into the sizer that was wxNotebookSizer's parent sizer in old code.
-- wxFile methods now return wxFileOffset which may be a 64 bit integer type,
-  even on 32 bit platforms, instead of off_t and so the return value of
-  wxFile::Length(), for example, shouldn't be assigned to off_t variable any
-  more (the compiler might warn you about this).
+- wxFile methods now return either wxFileOffset or wxFileSize_t which may be a

 - wxListItem::m_data is now of type wxUIntPtr, not long, for compatibility
   with 64 bit systems
