## Changelog since v1.5.5

### Other notable changes

* kube-up (with gce/gci and gce/coreos providers) now ensures the authentication token file contains correct tokens for the control plane components, even if the file already exists (ensures upgrades and downgrades work successfully) ([#43676](https://github.com/kubernetes/kubernetes/pull/43676), [@liggitt](https://github.com/liggitt))

- Upon receiving a LIST request with an expired continue token, the apiserver now returns a continue token together with the 410 "the from parameter is too old" error. If the client does not care about getting a list from a consistent snapshot, the client can use this token to continue listing from the next key, but the returned chunk will be from the latest snapshot. ([#67284](https://github.com/kubernetes/kubernetes/pull/67284),...

		scred := su.Credentials
		if scred.ParentUser != parentUser {
			return updatedAt, fmt.Errorf("%w: the service account access key is taken by another user", errIAMServiceAccountNotAllowed)
		}
		return updatedAt, fmt.Errorf("%w: the service account access key already taken", errIAMServiceAccountNotAllowed)
	}

	// Parent user must not be a service account.

* With this PR, kubectl and other RestClient's using the AuthProvider framework can make OIDC authenticated requests, and, if there is a refresh token present, the tokens will be refreshed as needed. ([#25270](https://github.com/kubernetes/kubernetes/pull/25270), [@bobbyrullo](https://github.com/bobbyrullo))

- Kube-apiserver can now specify `--authentication-token-webhook-version=v1` or `--authorization-webhook-version=v1` to use `v1` TokenReview and SubjectAccessReview API objects when communicating with authentication and authorization webhooks. ([#84768](https://github.com/kubernetes/kubernetes/pull/84768), [@liggitt](https://github.com/liggitt))

- Allowed creating ServiceAccount tokens bound to Node objects.
  This allows users to bind a service account token's validity to a named Node object, similar to Pod bound tokens.
