* The `system-node-critical` and `system-cluster-critical` priority classes are now limited to the `kube-system` namespace by the `PodPriority` admission plugin. ([#65593](https://github.com/kubernetes/kubernetes/pull/65593), [@bsalamat](https://github.com/bsalamat))

# Release 2.20.0

## TensorFlow

### Breaking Changes

* The `tensorflow-io-gcs-filesystem` package is now optional, due its uncertain, and limited support. To install it alongside `tensorflow`, run `pip install "tensorflow[gcs-filesystem]"`.

### Major Features and Improvements

* The `NodeRestriction` admission plugin limits the `Node` and `Pod` objects a kubelet can modify. In order to be limited by this admission plugin, kubelets must use credentials in the `system:nodes` group, with a username in the form `system:node:<nodeName>`. Such kubelets will only be allowed to modify their own `Node` API object, and only modify `Pod` API objects...

* Fixes a flaw (CVE-2019-11253) in json/yaml decoding where large or malformed documents could consume excessive server resources. Request bodies for normal API requests (create/delete/update/patch operations of regular resources) are now limited to 3MB. ([#83261](https://github.com/kubernetes/kubernetes/pull/83261), [@liggitt](https://github.com/liggitt))
