- Kubernetes 1.12 includes a large number of metadata agent improvements, including expanding the metadata agent's access to all API groups and removing metadata agent config maps in favor of command line flags. It also includes improvements to the logging agent, such as multiple fixes and adjustments.

    ```kotlin
      private val client = OkHttpClient()

      fun run() {
        val request = Request.Builder()
            .url("https://api.github.com/repos/square/okhttp/issues")
            .header("User-Agent", "OkHttp Headers.java")
            .addHeader("Accept", "application/json; q=0.5")
            .addHeader("Accept", "application/vnd.github.v3+json")
            .build()

* Add NoSchedule/NoExecute tolerations to ip-masq-agent, ensuring it to be scheduled in all nodes except master. ([#66260](https://github.com/kubernetes/kubernetes/pull/66260), [@tanshanshan](https://github.com/tanshanshan))
* Metadata Agent Improvements ([#66485](https://github.com/kubernetes/kubernetes/pull/66485), [@bmoyles0117](https://github.com/bmoyles0117))
    * Bump metadata agent version to 0.2-0.0.21-1.

 *  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.

**Step 1: Export GSA Configuration**

Export your GSA configuration as XML. A typical GSA configuration includes:
- Collections with URL patterns
- Start URLs and crawl rules
- User agent settings
- Good/bad URL patterns

**Step 2: Import via Fess Admin UI**

1. Log in to Fess Admin Console: `http://<fess-server>:8080/admin`
2. Navigate to **System > Backup**
