*  New: Publish a [bill of materials (BOM)][bom] for OkHttp. Depend on this from Gradle or Maven to
    keep all of your OkHttp artifacts on the same version, even if they're declared via transitive
    dependencies. You can even omit versions when declaring other OkHttp dependencies.

    ```kotlin
    dependencies {
       api(platform("com.squareup.okhttp3:okhttp-bom:4.4.0"))

// TODO reenable other tests
// https://github.com/square/okhttp/issues/8901

//    java.srcDirs(
//      "../okhttp-brotli/src/test/java",

//      "../okhttp-logging-interceptor/src/test/java",
//      "../okhttp-sse/src/test/java",
//    )
//  }
//}

prevent a response from using the cache, use [`CacheControl.FORCE_NETWORK`](http://square.github.io/okhttp/4.x/okhttp/okhttp3/-cache-control/-f-o-r-c-e_-n-e-t-w-o-r-k/). To prevent it from using the network, use [`CacheControl.FORCE_CACHE`](http://square.github.io/okhttp/4.x/okhttp/okhttp3/-cache-control/-f-o-r-c-e_-c-a-c-h-e/). Be warned: if you use `FORCE_CACHE` and the response requires the network, OkHttp will return a `504 Unsatisfiable Request` response.

 *  **URLConnection support has moved to the okhttp-urlconnection module.**
    If you're upgrading from 1.x, this change will impact you. You will need to
    add the `okhttp-urlconnection` module to your project and use the
    `OkUrlFactory` to create new instances of `HttpURLConnection`:

    ```java
    // OkHttp 1.x:
    HttpURLConnection connection = client.open(url);

    // OkHttp 2.x:

/**
 * Protocols that OkHttp implements for [ALPN][ietf_alpn] selection.
 *
 * ## Protocol vs Scheme
 *
 * Despite its name, [java.net.URL.getProtocol] returns the [scheme][java.net.URI.getScheme] (http,
 * https, etc.) of the URL, not the protocol (http/1.1, spdy/3.1, etc.). OkHttp uses the word
 * *protocol* to identify how HTTP messages are framed.
