#### 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. ([#74877](https://github.com/kubernetes/kubernetes/pull/74877), [@liggitt](https://github.com/liggitt))

#### Apps

* Added a `kubeadm config images list` command that lists required container images for a kubeadm install. ([#63450](https://github.com/kubernetes/kubernetes/pull/63450), [@chuckha](https://github.com/chuckha))
