 *  New: The `okhttp-zstd` module negotiates [Zstandard (zstd)][zstd] compression with servers that
    support it. It integrates a new (unstable) [ZSTD-KMP] library, also from Square. Enable it like
    this:

    ```kotlin
    val client = OkHttpClient.Builder()

// The stream is s2 compressed.
// https://github.com/klauspost/compress/tree/master/s2#s2-compression

//
// All stream elements are msgpack encoded.
//
