   * Adds near duplicate of code owner middleware from edx-django-utils.
-  * Adds code owner for celery using Datadog span processing of celery.run spans.
+  * Adds code owner span tags for celery using Datadog span processing of celery.run spans.
   * Uses temporary span tags names using ``_2``, like ``code_owner_2``, for rollout and comparison with the original span tags.
+  * Span tag code_owner_2_module includes the task name, where the original code_owner_module does not. In both cases, the code owner is computed the same, because it is based on a prefix match.
