+    Support for the Linux s390x platform has changed from tier 3 to tier 4 (as
+    documented in :ref:`platform-suppport`). This is a result of no longer being
+    able to run tests during the pre-compiled wheel publishing jobs due to
+    constraints in the available CI infrastructure. There hopefully shouldn't 
+    be any meaningful impact resulting from this change, but as there are no longer tests being
+    run to validate the binaries prior to publishing them there are no longer
+    guarantees that the wheels for s390x are fully functional (although the
+    likelihood they are is still high as it works on other platforms). If any
+    issues are encountered with s390x Linux please open an issue.
