    support it. It integrates a new (unstable) [ZSTD-KMP] library, also from Square. Enable it like
    this:

    ```kotlin
    val client = OkHttpClient.Builder()
      .addInterceptor(CompressionInterceptor(Zstd, Gzip))
      .build()
    ```

 *  New: Support the `QUERY` HTTP method. You will need to set the `Request.cacheUrlOverride`
    property to cache calls made with this method. The `RequestBody.sha256()` may be helpful here;
