### Bug or Regression

- Admission webhooks can now return warning messages that are surfaced to API clients, using the `.response.warnings` field in the admission review response. ([#92667](https://github.com/kubernetes/kubernetes/pull/92667), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]
- CertificateSigningRequest API conditions were updated:

- 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))

- Azure ARM client: don't segfault on empty response and http error ([#94078](https://github.com/kubernetes/kubernetes/pull/94078), [@bpineau](https://github.com/bpineau)) [SIG Cloud Provider]

* This fix prevents a GCE PD volume from being mounted if the udev device link is stale and tries to correct the link....

  The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code.

## Changes by Kind

### API Change

- 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))

```

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

- Fixed API response for `StorageClassList` queries to return a graceful error message, if the provided `ResourceVersion` is too large. ([#132374](https://github.com/kubernetes/kubernetes/pull/132374), [@PatrickLaabs](https://github.com/PatrickLaabs)) [SIG API Machinery...
