 *  New: Enforce label length limits in URLs. `HttpUrl` now rejects URLs whose domains aren't valid.
    This includes overly-long domain names (longer than 253 characters), overly-long labels (more
    than 63 characters between dots), and empty labels.
 *  New: Don't include the `Content-Length` header in multipart bodies. Servers must delimit

 * strictly ASCII. This is intended to make it efficient to encode this data as a string, and to
 * index into it as a string.
 *
 * The mappings data contains non-ASCII characters.
