New ``close-figs`` argument for plot directive
70+
----------------------------------------------
71+
72+
Matplotlib has a sphinx extension ``plot_directive`` that creates plots for
73+
inclusion in sphinx documents. Matplotlib 1.5 adds a new option to the plot
74+
directive - ``close-figs`` - that closes any previous figure windows before
75+
creating the plots. This can help avoid some surprising duplicates of plots
76+
when using ``plot_directive``.
