    application code that creates challenges.

 *  New: The `TlsVersion` of a `Handshake` is now non-null. If you are calling
    `Handshake.get()` with a null TLS version, you must instead now provide a
    non-null `TlsVersion`. Cache responses persisted prior to OkHttp 3.0 did not
    store a TLS version; for these unknown values the handshake is defaulted to
    `TlsVersion.SSL_3_0`.

 *  New: Upgrade to Okio 1.13.0.
