### Other notable changes

* We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not.  ([#41363](https://github.com/kubernetes/kubernetes/pull/41363), [@jingxu97](https://github.com/jingxu97))

  - The `export` query parameter for list API calls is deprecated and will be removed in v1.18 ([#73783](https://github.com/kubernetes/kubernetes/pull/73783), [@deads2k](https://github.com/deads2k))

              LoadingValueReference.this.set(newResult);
              return newResult;
            },

- The `export` query parameter (inconsistently supported by API resources and deprecated in v1.14) is fully removed.  Requests setting this query parameter will now receive a 400 status response.
