  As this code is still very new, it has not been heavily optimized yet;
  while it is expected to _eventually_ have better performance than the
  iptables backend, very little performance testing has been done so far. ([#121046](https://github.com/kubernetes/kubernetes/pull/121046), [@danwinship](https://github.com/danwinship))

- 'The iptables kube-proxy backend now process service/endpoint changes
  more efficiently in very large clusters.' ([#110268](https://github.com/kubernetes/kubernetes/pull/110268), [@danwinship](https://github.com/danwinship))
- '`CSIMigrationvSphere` was upgraded to GA and locked to true. Do not upgrade to K8s

### 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))

* ✨ Add `description` parameter to all the security scheme classes, e.g. `APIKeyQuery(name="key", description="A very cool API key")`. PR [#1757](https://github.com/tiangolo/fastapi/pull/1757) by [@hylkepostma](https://github.com/hylkepostma).

// New uses of this type are discouraged because of difficulty describing its usage when embedded in APIs.
//  1. Ignored fields.  It includes many fields which are not generally honored.  For instance, ResourceVersion and FieldPath are both very rarely valid in actual usage.
//  2. Invalid usage help.  It is impossible to add specific help for individual usage.  In most embedded usages, there are particular
