   * SoftReference} (by default, strong references are used). Softly-referenced objects will be
   * garbage-collected in a <i>globally</i> least-recently-used manner, in response to memory
   * demand.
   *
   * <p><b>Warning:</b> in most circumstances it is better to set a per-cache {@linkplain
   * #maximumSize(long) maximum size} instead of using soft references. You should only use this

### Bug or Regression

- Added `apiserver_watch_list_duration_seconds` metrics which will measure response latency distribution in seconds for watchlist requests broken by group, version, resource and scope. ([#120490](https://github.com/kubernetes/kubernetes/pull/120490), [@p0lyn0mial](https://github.com/p0lyn0mial))

### API Change

- A new field `omitManagedFields` has been added to both `audit.Policy` and `audit.PolicyRule` 
  so cluster operators can opt in to omit managed fields of the request and response bodies from 
  being written to the API audit log. ([#94986](https://github.com/kubernetes/kubernetes/pull/94986), [@tkashem](https://github.com/tkashem)) [SIG API Machinery, Auth, Cloud Provider and Testing]

## Before Upgrading

* When Response is a `metav1.Status`, it is no longer copied into the audit.Event status. Only the "status", "reason" and "code" fields are set.  For example, when we run `kubectl get pods abc`, the API Server returns a status object:

```

Check if event notification is successfully configured by

```
mc event list myminio/images
```

You should get a response like this

```
arn:minio:sqs::1:webhook   s3:ObjectCreated:*   Filter: suffix=".jpg"
```

### Step 3: Test with Thumbnailer

- Kube-proxy service health returns http header `X-Load-Balancing-Endpoint-Weight` with number of local endpoints. The same information is still available in response body JSON `payload.LocalEndpoints`. ([#118999](https://github.com/kubernetes/kubernetes/pull/118999), [@cezarygerard](https://github.com/cezarygerard))

// DeletePolicy - deletes policy from storage and cache. When this called in
// response to a notification (i.e. isFromNotification = true), it skips the
// validation of policy usage and the attempt to delete in the backend as well
// (as this is already done by the notifying node).
