## Kubefed

    *  - `kubernetes` plugin adds metrics to measure kubernetes control plane latency.
    *  -  the `health` plugin now includes the `lameduck` option by default, which waits for a duration before shutting down.
* Kubeadm now includes CoreDNS version 1.6.5 ([#85108](https://github.com/kubernetes/kubernetes/pull/85108), [@rajansandeep](https://github.com/rajansandeep))

#### Continuous Improvement
- Project sustainability is not just about features. Many SIGs have been working on  improving test coverage, ensuring the basics stay reliable, and stability of the core feature set and working on maturing existing features and cleaning up the backlog.

#### Extensibility

- Added apiserver_envelope_encryption_invalid_key_id_from_status_total to measure number of times an invalid keyID is returned by the Status RPC call. ([#115846](https://github.com/kubernetes/kubernetes/pull/115846), [@ritazh](https://github.com/ritazh)) [SIG API Machinery and Auth]
