-    The ``qiskit.visualization.transition_visualization`` module has been deprecated
-    and will be removed in a future release. Refer to
-    `#9355 <https://github.com/Qiskit/qiskit/issues/9355>`__ for more details.
+    The :func:`.transition_visualization` function has been deprecated and will
+    be removed in the 2.0.0 release. This function had a number of limitations
+    which limited it's utility to only very specific use cases and didn't fit in with
+    the rest of the Qiskit visualization module.
