### Runtime log sanitation

Logs can now be configured to use runtime protection from leaking sensitive data. [Details for this experimental feature is available in documentation](https://docs.k8s.io/concepts/cluster-administration/system-logs/#log-sanitization).

- Fixed a regression that sometimes prevented `kubectl portforward` to work when TCP and UDP services were configured on the same port ([#94728](https://github.com/kubernetes/kubernetes/pull/94728), [@amorenoz](https://github.com/amorenoz)) [SIG CLI]

Reverts graceful node shutdown to match 1.21 behavior of setting pods that have not yet successfully completed to "Failed" phase if the GracefulNodeShutdown feature is enabled in kubelet. The GracefulNodeShutdown feature is beta and must be explicitly configured via kubelet config to be enabled in 1.21+. This changes 1.22 and 1.23 behavior on node shutdown to match 1.21. If you do not want pods to be marked terminated on node shutdown in 1.22 and 1.23, disable the GracefulNodeShutdown feature. ([#10689...

- Fixing issue with Winkernel Proxier - IPV6 load balancer policies are missing when service is configured with ipFamilyPolicy: RequireDualStack ([#115615](https://github.com/kubernetes/kubernetes/pull/115615), [@princepereira](https://github.com/princepereira)) [SIG Network]

    - To allow Azure cloud provider to read secrets, the [RBAC rules](https://github.com/kubernetes/kubernetes/pull/78242) should be configured.

#### CLI

- `kubectl scale job`, deprecated since 1.10, has been removed. ([#78445](https://github.com/kubernetes/kubernetes/pull/78445), [@soltysh](https://github.com/soltysh))

   ([#122276](https://github.com/kubernetes/kubernetes/pull/122276), [@pohly](https://github.com/pohly))
- Added a CBOR implementation of `runtime.Serializer`. Until CBOR graduates to Alpha, API servers will refuse to start if configured with CBOR support. ([#122881](https://github.com/kubernetes/kubernetes/pull/122881), [@benluddy](https://github.com/benluddy))
- Added a alpha feature, behind the `RelaxedEnvironmentVariableValidation` feature gate.

    - `apiserver_flowcontrol_nominal_limit_seats`: Nominal number of execution seats configured for each priority level
    - `apiserver_flowcontrol_lower_limit_seats`: Configured lower bound on number of execution seats available to each priority level
    - `apiserver_flowcontrol_upper_limit_seats`: Configured upper bound on number of execution seats available to each priority level

  - The `ValidateProxyRedirects` feature was promoted to Beta and enabled by default. This feature restricts redirect-following from the apiserver to same-host redirects.  If nodes are configured to respond to CRI streaming requests on a different host interface than what the apiserver makes requests on (only the case if not using the built-in dockershim & setting the kubelet flag `--redirect-container-streaming=true`), then these requests...

- Kubernetes is now built with Go `v1.21.3`. ([#121149](https://github.com/kubernetes/kubernetes/pull/121149), [@cpanato](https://github.com/cpanato))
- List of metric labels can now be configured by supplying a manifest using the `--allow-metric-labels-manifest` flag. ([#118299](https://github.com/kubernetes/kubernetes/pull/118299), [@rexagod](https://github.com/rexagod))

if it encounters a networking failure (e.g. the networking interface hosting its address goes away) to allow a process manager (systemd/kubelet/etc) to react to the problem. Previously the server would log the failure and try again to bind to its configured address:port. ([#42272](https://github.com/kubernetes/kubernetes/pull/42272), [@marun](https://github.com/marun))
