### Feature

- A new client side metric `rest_client_request_retries_total` has been added that tracks the number of retries sent to the server, partitioned by status code, verb and host ([#108396](https://github.com/kubernetes/kubernetes/pull/108396), [@tkashem](https://github.com/tkashem))

- Update the Event series starting count when emitting isomorphic events from 1 to 2. ([#119375](https://github.com/kubernetes/kubernetes/pull/119375), [@dgrisonnet](https://github.com/dgrisonnet)) [SIG API Machinery and Testing]

#### Monitoring/Prometheus
* [action required] The WATCHLIST calls are now reported as WATCH verbs in prometheus for the apiserver_request_* series.  A new "scope" label is added to all apiserver_request_* values that is either 'cluster', 'resource', or 'namespace' depending on which level the query is performed at.([#52237](https://github.com/kubernetes/kubernetes/pull/52237))

  - The `export` query parameter for list API calls, deprecated since v1.14, will be removed in v1.18.
  - The `series.state` field in the events.k8s.io/v1beta1 Event API is deprecated and will be removed in v1.18 ([#75987](https://github.com/kubernetes/kubernetes/pull/75987), [@yastij](https://github.com/yastij))
