- Fixes a regression in v1beta1 PodDisruptionBudget handling of `strategic merge patch`-type API requests for the `selector` field. Prior to 1.21, these requests would merge `matchLabels` content and replace `matchExpressions` content. In 1.21, patch requests touching the `selector` field started replacing the entire selector. This is consistent with server-side apply and the v1 PodDisruptionBudget behavior, but should...

  Jobs created before the feature was enabled are still tracked without finalizers.
  Jobs tracked with finalizers have the annotation batch.kubernetes.io/job-tracking.
  If the annotation is present and the user attempts to remove it, the control plane adds it back.
  The annotation `batch.kubernetes.io/job-tracking` is now deprecated.

requests in webhook authorization calls. Promoted `AuthorizeNodeWithSelectors` feature to beta, which changes node authorizer behavior to limit requests from node API clients, so that each Node can only get / list / watch its own Node API object, and can also only get / list / watch Pod API objects bound to that node. Clients using kubelet credentials to read other nodes or unrelated pods must change their authentication credentials (recommended), adjust their usage, or obtain broader read access...

- Kubeadm: enhanced the "patches" functionality to be able to patch kubelet config files containing `v1beta1.KubeletConfiguration`. The new patch target is called `kubeletconfiguration` (e.g. patch file `kubeletconfiguration+json.json`).This makes it possible to apply node specific KubeletConfiguration options during `init`, `join` and `upgrade`, while the main `KubeletConfiguration`...
