+Legacy Python Bindings
+----------------------
+
+The legacy python bindings previously in `bindings/python` are no
+longer supported. These bindings have been deprecated since 2020. As
+of this release they are no longer built or tested, and patches for
+them will no longer be accepted. They have been moved to `contrib` to
+smooth the transition. Thanks very much to Sebastian Spaeth and all of
+the other contributors to these bindings over the years.
