* The following deprecated flags were removed from `kube-controller-manager`:

  * `replication-controller-lookup-cache-size`
  * `replicaset-lookup-cache-size`
  * `daemonset-lookup-cache-size`

  Don't use these flags. Using deprecated flags causes the server to print a warning. Using a removed flag causes the server to abort the startup.

* The following deprecated flags were removed from `kubelet`:

- `kube-apiserver`: added `--authorization-config` flag for reading a configuration file containing an `apiserver.config.k8s.io/v1alpha1 AuthorizationConfiguration` object. The `--authorization-config` flag is mutually exclusive with `--authorization-modes` and `--authorization-webhook-*` flags. The `alpha` `StructuredAuthorizationConfiguration` feature flag must be enabled for `--authorization-config` to be specified. ([#120154](https://github.com/kub...

- Added a `--prune-allowlist` flag that can be used with `kubectl apply --prune`. This flag replaces and functions the same as the `--prune-whitelist` flag, which has been deprecated. ([#113116](https://github.com/kubernetes/kubernetes/pull/113116), [@brianpursley](https://github.com/brianpursley)) [SIG CLI]

- Added '--concurrent-cron-job-syncs' flag for `kube-controller-manager` to set the number of workers for cron job controller. ([#117550](https://github.com/kubernetes/kubernetes/pull/117550), [@borgerli](https://github.com/borgerli))

- Kubelet: remove deprecated flag `--container-runtime` ([#114017](https://github.com/kubernetes/kubernetes/pull/114017), [@calvin0327](https://github.com/calvin0327)) [SIG Cloud Provider and Node]
- Kubelet: the deprecated `--master-service-namespace` flag is removed in v1.27 ([#116015](https://github.com/kubernetes/kubernetes/pull/116015), [@SataQiu](https://github.com/SataQiu))
