+  .. note:: Due to the urgency of 5.0.2 release, the following modules are
+            pinned to the same versions as 5.0.1: PMIx(v4.2.8), PRRTe(v3.0.3).
+            This ensures the modules always refer to stable releases that can
+            be matched by external installations.
+            As a result, changes in newer PMIx/PRRTe are excluded, notably:
+            PRRTe
