- GCE/Windows: added support for the stackdriver logging agent ([#76850](https://github.com/kubernetes/kubernetes/pull/76850), [@yujuhong](https://github.com/yujuhong))

 *  New: Constant string `okhttp3.VERSION`. This is a string like "4.5.0-RC1", "4.5.0", or
    "4.6.0-SNAPSHOT" indicating the version of OkHttp in the current runtime. Use this to include
    the OkHttp version in custom `User-Agent` headers.

 *  Fix: Don't crash when running as a plugin in Android Studio Canary 4.1. To enable
    platform-specific TLS features OkHttp must detect whether it's running in a JVM or in Android.

	* ip-masq-agent is now on by default for GCE ([#47794](https://github.com/kubernetes/kubernetes/pull/47794), [@dnardo](https://github.com/dnardo))

  - ip-mask-agent addon starts to use the label `node.kubernetes.io/masq-agent-ds-ready` instead of `beta.kubernetes.io/masq-agent-ds-ready` as its node selector.

		"User-Agent":                   []string{"A malicious request"},
		"X-Amz-Decoded-Content-Length": []string{"8"},
		"Content-Encoding":             []string{"aws-chunked"},
		"X-Amz-Trailer":                []string{"x-amz-checksum-crc32"},

     * Simplified way to run a container on every node (DaemonSet API (Beta) in the
Extensions API group): Kubernetes can schedule a service (such as a logging
agent) that runs one, and only one, pod per node.
     * TLS and L7 support (Ingress API (Beta) in the Extensions API group): Kubernetes
is now easier to integrate into custom networking environments by supporting

* Bump ip-masq-agent version to v2.3.0 to fix vulnerabilities ([#77833](https://github.com/kubernetes/kubernetes/pull/77833), [@anfernee](https://github.com/anfernee))
