(cherry picked from commit 6c3ce18e17)

CHANGES.rst

@@ -110,6 +110,12 @@ Changes in this release include the following:
 * Change wx.TextCompleterSimple.GetCompletions to send the list of strings
   as a return value, rather than a parameter that gets filled. (#836)
 
+* Enabled the wx.GraphicsContext.Create(metaFileDC) wrapper (#811)
+
+* Metafile support is also available on OSX, so wx.msw.Metafile and
+  wx.msw.MetafileDC have been moved to the core wx module. So they can now be
+  accessed as wx.Metafile and wx.MetafileDC.
