* DELETE requests can now pass in their DeleteOptions as a query parameter or a body parameter, rather than just as a body parameter. ([#35806](https://github.com/kubernetes/kubernetes/pull/35806), [@bdbauer](https://github.com/bdbauer))

* Added a way to pass extra arguments to etcd. The these extra arguments can be used to adjust runtime configuration like heartbeat interval etc. ([#63961](https://github.com/kubernetes/kubernetes/pull/63961), [@mborsz](https://github.com/mborsz))

    overrides the stored "Content-Encoding" header.
 *  Fix: Gracefully shut down the HTTP/2 connection before it exhausts the
    namespace of stream IDs (~536 million streams).
 *  Fix: Never pass a null `Route` to `Authenticator`. There was a bug where
    routes were omitted for eagerly-closed connections.

`--pod-infra-container-image` flag from `kubelet` command line. For `non-kubeadm` clusters, users must manually remove this flag from their `kubelet` configuration to prevent startup failures before upgrading `kubelet`. For `kubeadm` clusters, if users pass extra arguments to the `kubelet` like `--pod-infra-container-image`, it will be written to the `kubelet` env file during the `init` phase. `kubeadm` does not remove it during the `init` or `join` phase, so users must manually remove it from `extraArgs`...

* make node lease renew interval more heuristic based on node-status-update-frequency in kubelet ([#80173](https://github.com/kubernetes/kubernetes/pull/80173), [@gaorong](https://github.com/gaorong))
