#### New API fields:

- Go clients created from a kubeconfig that specifies a TokenFile now periodically reload the token from the specified file. ([#70606](https://github.com/kubernetes/kubernetes/pull/70606), [@mikedanese](https://github.com/mikedanese))

- If the user specifies an invalid timeout in the request URL, the request will be aborted with an HTTP 400.

- Kubelet: a configuration file specified via `--config` is now loaded with strict deserialization, which fails if the config...

  - Added an additional identifier to `ResourceClaim.Status` for the device supports multiple allocations.

that evicts already-running pods, and an associated `tolerationSeconds` field to tolerations to delay the eviction for a specified amount of time. As before, taints are created using `kubectl taint` (but internally they are now represented as a field `taints` in the NodeSpec rather than using the `scheduler.alpha.kubernetes.io/taints` annotation on Node). Tolerations are now specified in a new-in-1.6 `tolerations` field of the PodSpec rather than using the `scheduler.alpha.kubernetes.io/tolerations`...

  The "audienceMatchPolicy" can be empty (or unset) when a single audience is specified in the "audiences" field.
  The "audienceMatchPolicy" must be set to "MatchAny" when multiple audiences are specified in the "audiences" field. ([#123165](https://github.com/kubernetes/kubernetes/pull/123165), [@aramase](https://github.com/aramase))

- kube-proxy

  - the `--resource-container` flag has been removed from kube-proxy, and specifying it will now cause an error. The behavior is now as if you specified `--resource-container=""`. If you previously specified a non-empty `--resource-container`, you can no longer do so as of kubernetes 1.16. ([#78294](https://github.com/kubernetes/kubernetes/pull/78294), [@vllry](https://github.com/vllry))

- kube-scheduler

`kubernetes.io/legacy-token-invalid-since` label if the credentials have not been used in the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year), **and** are referenced from the `.secrets` list of a ServiceAccount object, **and**  are not referenced from pods. This label causes the authentication layer to reject use of the credentials. After being labeled as invalid, if the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year) passes...

- Specifies the deprecated version of apiserver_storage_objects metric in metrics docs ([#134028](https://github.com/kubernetes/kubernetes/pull/134028), [@richabanker](https://github.com/richabanker)) [SIG API Machinery, Etcd and Instrumentation]
