When enabled, `kube-proxy` will not install the `DROP` rule for invalid conntrack states, which currently breaks users of asymmetric routing.

  Users that self-deploy Kubernetes on vSphere should enable CSIMigration + CSIMigrationvSphere features and install the vSphere CSI Driver (https://github.com/kubernetes-sigs/vsphere-csi-driver) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the vSphere CSI driver directly for any new volumes.

- KMS Providers will install a healthz check for the status of kms-plugin in kube-apiservers' encryption config. ([#78540](https://github.com/kubernetes/kubernetes/pull/78540), [@immutableT](https://github.com/immutableT))

- The cluster addon for dashboard was removed. To install dashboard, see [here](https://github.com/kubernetes/dashboard/blob/master/docs/user/README.md). ([#107481](https://github.com/kubernetes/kubernetes/pull/107481), [@shu-mutou](https://github.com/shu-mutou))

#### API Machinery

- `k8s.io/kubernetes` and published components (such as `k8s.io/client-go` and `k8s.io/api`) now contain go module files including dependency version information. See [go-modules](http://git.k8s.io/client-go/INSTALL.md#go-modules) for details on consuming `k8s.io/client-go` using go modules.
