+3.9.0 (Under devlopment)
+------------------------
+
+
+Changed
+^^^^^^^
+
+
+* The :class:`.Image` class no longer uses an :class:`.ImageWrapper` to
+  manage data access and assignment.
+* Semantics for accessing and modifying image data via the
+  :meth:`.Image.__getitem__` and :meth:`.Image.__setitem__` methods have
+  been clarified.
+
+
+Deprecated
+^^^^^^^^^^
+
+* The :mod:`.imagewrapper` module (and the :class:`.ImageWrapper` class) is
+  being migrated to FSLeyes - it, and all associated functions and options
+  in the :class:`.Image` class, have been marked as deprecated.
