*   Relies on CNI 0.6.0 binaries for IPv6 pod networking.
    *   Adds IPv6 support for kube-dns using SRV records.
    *   Caveats
        *   Only the CNI bridge and local-ipam plugins have been tested for the alpha release, although other CNI plugins do support IPv6.
        *   HostPorts are not supported.

* Allow setting the Host header in a httpGet probe ([#24292](https://github.com/kubernetes/kubernetes/pull/24292), [@errm](https://github.com/errm))
* Bridge off-cluster traffic into services by masquerading. ([#24429](https://github.com/kubernetes/kubernetes/pull/24429), [@cjcullen](https://github.com/cjcullen))

* Incremental improvements to kubelet e2e tests ([#24426](https://github.com/kubernetes/kubernetes/pull/24426), [@pwittrock](https://github.com/pwittrock))
* Bridge off-cluster traffic into services by masquerading. ([#24429](https://github.com/kubernetes/kubernetes/pull/24429), [@cjcullen](https://github.com/cjcullen))

- Fixed a bug in scheduler requeueing where registered wildcard cluster event sources didn't work. ([#123117](https://github.com/kubernetes/kubernetes/pull/123117), [@kerthcet](https://github.com/kerthcet))

      * no environment variables will be exposed ever via /metrics, even if whitelisted
* Filter duplicate network packets in promiscuous bridge mode (with ebtables) ([#28717](https://github.com/kubernetes/kubernetes/pull/28717), [@freehan](https://github.com/freehan))

    You can disable CRI explicitly (`--enable-cri=false`) as a
    temporary workaround.
      * The standard `bridge` plugin have been validated to interoperate with
         the new CRI + CNI code path.
      * If you are using plugins other than `bridge`, make sure you have
        updated custom plugins to the latest version that is compatible.
* **CNI plugins now affect node readiness**

- Adds support for `InterfaceNamePrefix` and `BridgeInterface` as arguments to `--detect-local-mode` option and also introduces a new optional `--pod-interface-name-prefix` and `--pod-bridge-interface` flags to kube-proxy.
