* API fields that previously serialized null arrays as `null` and empty arrays as `[]` no longer distinguish between those values and always output `[]` when serializing to JSON. ([#43422](https://github.com/kubernetes/kubernetes/pull/43422), [@liggitt](https://github.com/liggitt))

* Protobuf serialization does not distinguish between `[]` and `null`. ([#45294](https://github.com/kubernetes/kubernetes/pull/45294), [@liggitt](https://github.com/liggitt))

- kubeadm: remove the AuditPolicyConfiguration feature gate ([#70807](https://github.com/kubernetes/kubernetes/pull/70807), [@Klaven](https://github.com/Klaven))
- kubeadm pre-pulls Etcd image only if external Etcd is not used and --etcd-upgrade=false is not specified ([#70743](https://github.com/kubernetes/kubernetes/pull/70743), [@bart0sh](https://github.com/bart0sh))

- Kubelet: a "maxParallelImagePulls" field can now be specified in the kubelet configuration file to control how many image pulls the kubelet can perform in parallel. ([#115220](https://github.com/kubernetes/kubernetes/pull/115220), [@ruiwen-zhao](https://github.com/ruiwen-zhao)) [SIG API Machinery, Node and Scalability]

API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field)
can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6).

- New configuration is introduced to the kubelet that allows it to track container images and the list of authentication information that leads to their successful pulls. This data is persisted across reboots of the host and restarts of the kubelet.
