*  Fix: Read the response even if writing the request fails. This means you'll get a proper HTTP
    response even if the server rejects your request body.
 *  Fix: Use literal IP addresses directly rather than passing them to `DnsOverHttps`.
 *  Fix: Embed Proguard rules to prevent warnings from tools like DexGuard and R8. These warnings
    were triggered by OkHttp’s feature detection for TLS packages like `org.conscrypt`,

 *   at okhttp3.Connection.connect(Connection.java)
 *   at okhttp3.Connection.connectAndSetOwner(Connection.java)

 * Follow up by pasting the public key hashes from the exception into the
 * certificate pinner's configuration:
 *
 * ```java
 * CertificatePinner certificatePinner = new CertificatePinner.Builder()

  fun newBuilder(): Builder = commonNewBuilder()

   * according to this method. In particular, none of the following sets of headers are equal
   * according to this method:

 * if any intersection is found. The sizes of both arguments are assumed to be so small, and the
 * likelihood of an intersection so great, that it is not worth the CPU cost of sorting or the
 * memory cost of hashing.

 *  **`Request.Builder` no longer accepts null if a request body is required.**
    Passing null will now fail for request methods that require a body. Instead
    use an empty body such as this one:

        RequestBody.create(null, new byte[0]);
    ```
