+The *origin* parameter to ``_FigureCanvasWxBase.gui_repaint`` is deprecated
+with no replacement; ``gui_repaint`` now automatically detects the case where
+it is used with the wx renderer.

+The ``NavigationToolbar2Wx.get_canvas`` method is deprecated; directly
+instantiate a canvas (``FigureCanvasWxAgg(frame, -1, figure)``) if needed.
