 Other Changes
 =============
 
+Arrow support
+^^^^^^^^^^^^^
+
+`Arrow <https://arrow.apache.org/>`__ is an in-memory data exchange format that is the
+spiritual successor to the NumPy array interface. It provides for zero-copy access to
+columnar data, which in our case is ``Image`` data.
+
+To create an image with zero-copy shared memory from an object exporting the
+arrow_c_array interface protocol::
+
+    from PIL import Image
+    import pyarrow as pa
+    arr = pa.array([0]*(5*5*4), type=pa.uint8())
+    im = Image.fromarrow(arr, 'RGBA', (5, 5))
+
+Pillow images can also be converted to Arrow objects::
+
+    from PIL import Image
+    import pyarrow as pa
+    im = Image.open('hopper.jpg')
+    arr = pa.array(im)
+
