+Optimized ImageStat.Stat count and extrema
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Calculating the :py:attr:`~PIL.ImageStat.Stat.count` and
+:py:attr:`~PIL.ImageStat.Stat.extrema` statistics is now faster. After the
+histogram is created in ``st = ImageStat.Stat(im)``, ``st.count`` is 3x as fast
+on average and ``st.extrema`` is 12x as fast on average.
