* You must now specify `Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey` when using dynamic Kubelet config to tell the Kubelet which key of the `ConfigMap` identifies its config file. ([#59847](https://github.com/kubernetes/kubernetes/pull/59847), [@mtaufen](https://github.com/mtaufen))

#### Cluster Discovery/Bootstrap

* [beta] The authentication and verification mechanism called Bootstrap Tokens is improved. Use Bootstrap Tokens to easily add new node identities to a cluster. ([#130](https://github.com/kubernetes/enhancements/issues/130), [@luxas](https://github.com/luxas), [@jbeda](https://github.com/jbeda)).

#### Multi-platform

of a module in a particular version or version constraint. It is composed of a ModuleId, a revision, and optionally a branch and extra attributes. ArtifactId identifies an artifact without considering its version. It's basically a ModuleId and an artifact name, type and extension, plus optional extra attributes. ArtifactRevisionId identifies an artifact of a module in a particular version. It is composed of a ModuleRevisionId along with artifact identifier like the name type and extension.
