+Writing XMP bytes to JPEG and MPO
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+XMP data can now be saved to JPEG files using an ``xmp`` argument.
+```python
+im.save("out.jpg", xmp=b"test")
+```
+
+The data can also be set  through :py:attr:`~PIL.Image.Image.info`, for use when saving
+either JPEG or MPO images.
+```python
+im.info["xmp"] = b"test"
+im.save("out.jpg")
+```
