    - Leaked File descriptors ([#275](https://github.com/docker/containerd/issues/275))
    - Additional memory overhead per container ([#21737]((https://github.com/docker/docker/issues/21737))
  * Docker version 1.12.1 [has been validated](https://github.com/kubernetes/kubernetes/issues/28698) through the Kubernetes docker automated validation framework as has Docker version 1.12.3

- The minimum value validation of ReplicationController's `replicas` and `minReadySeconds` fields have been migrated to declarative validation. The requiredness of both fields is also declaratively validated.
  If the `DeclarativeValidation` feature gate is enabled, mismatches with existing validation are reported via metrics.

- Pod Affinity/AntiAffinity label selectors are now validated in the pod affinity score plugin ([#93758](https://github.com/kubernetes/kubernetes/pull/93758), [@damemi](https://github.com/damemi)) [SIG Scheduling]

* Kubelet: Start using the official docker engine-api ([#23506](https://github.com/kubernetes/kubernetes/pull/23506), [@Random-Liu](https://github.com/Random-Liu))
* Fix so setup-files don't recreate/invalidate certificates that already exist ([#23550](https://github.com/kubernetes/kubernetes/pull/23550), [@luxas](https://github.com/luxas))
