+Removed `Lena` images from sample_data
+``````````````````````````````````````
+
+The ``lena.png`` and ``lena.jpg`` images have been removed from
+matplotlibs sample_data directory. The images are also no longer
+available from `matplotlib.cbook.get_sample_data`. We suggest using
+`matplotlib.cbook.get_sample_data('grace_hopper.png')` or
+`matplotlib.cbook.get_sample_data('grace_hopper.jpg')` instead.
