+### Announcements
+
+- There was a breaking change to `cloud.google.com/go/dataproc/apiv1` that was
+ merged in [this PR](https://github.com/googleapis/google-cloud-go/pull/2606).
+ This fixed a broken API response for `DiagnoseCluster`. When polling on the
+ Long Running Operation(LRO), the API now returns
+ `(*dataprocpb.DiagnoseClusterResults, error)` whereas it only returned an
+ `error` before.
