+New ``close-figs`` argument for plot directive
+----------------------------------------------
+
+Matplotlib has a sphinx extension ``plot_directive`` that creates plots for
+inclusion in sphinx documents.  Matplotlib 1.5 adds a new option to the plot
+directive - ``close-figs`` - that closes any previous figure windows before
+creating the plots.  This can help avoid some surprising duplicates of plots
+when using ``plot_directive``.
