+Support for specifying properties of wedge and text in pie charts.
+``````````````````````````````````````````````````````````````
+Added the `kwargs` 'wedgeprops' and 'textprops' to :func:`~matplotlib.Axes.pie`
+to accept properties for wedge and text objects in a pie. For example, one can
+specify wedgeprops = {'linewidth':3} to specify the width of the borders of
+the wedges in the pie. For more properties that the user can specify, look at
+the docs for the wedge and text objects.
