+!!! info "OCP 4.20+ conformance validation"
+    Validations on OCP 4.20+ were previously blocked by
+    [OCPBUGS-77783](https://issues.redhat.com/browse/OCPBUGS-77783) and
+    [OCPBUGS-84961](https://issues.redhat.com/browse/OCPBUGS-84961).
+    Both issues have been resolved and 4.20+ validations are now supported.
+
+    **Affected versions:**
+
+    - OPCT v0.6.4 and earlier do not support OCP 4.20+.
+    - OPCT v0.6.5+ is validated for OCP 4.19-4.22.
+
+    **Fix details:**
+
+    - The conformance suite fix is in `openshift-tests` ([openshift/origin](https://github.com/openshift/origin)),
+      not in OPCT. No OPCT plugin changes were required.
+    - OCP 4.20 was not affected by the conformance suite bug.
+    - OCP 4.21+ requires a nightly or z-stream release that includes the fix
+      ([origin PR #31353](https://github.com/openshift/origin/pull/31353) for 4.21,
+      [origin PR #31270](https://github.com/openshift/origin/pull/31270) for 4.22).
 
 It is highly recommended to use the latest OPCT version.
