*   `etcd2` as a backend is deprecated and support will be removed in Kubernetes 1.13 or 1.14.

*   Default controller-manager options for `--cluster-signing-cert-file` and `--cluster-signing-key-file` are deprecated and will be removed in a future release. ([#54495](https://github.com/kubernetes/kubernetes/pull/54495),[ @mikedanese](https://github.com/mikedanese))

- Kube-apiserver: Promoted the `ExternalServiceAccountTokenSigner` feature to beta, which enabled external signing of service account tokens and fetching of public verifying keys. This was accomplished by enabling the beta `ExternalServiceAccountTokenSigner` feature gate and specifying the `--service-account-signing-endpoint` flag. The flag value could either be the path to a Unix domain socket on the filesystem, or be prefixed with @ to indicate a Unix domain...

- The kube-controller-manager managed signers can now have distinct signing certificates and keys.  See the help about `--cluster-signing-[signer-name]-{cert,key}-file`.  `--cluster-signing-{cert,key}-file` is still the default.
