+
+Backwards Incompatible Changes
+==============================
+
+Setting image mode
+^^^^^^^^^^^^^^^^^^
+
+If you attempt to set the mode of an image directly, e.g.
+``im.mode = "RGBA"``, you will now receive an ``AttributeError``. This is
+not about removing existing functionality, but instead about raising an
+explicit error to prevent later consequences. The ``convert`` method is the
+correct way to change an image's mode.
