*  Fix: Don't crash when building `HandshakeCertificates` on Android API 28.
 *  Fix: Permit multipart file names to contain non-ASCII characters.
 *  New: API to get MockWebServer's dispatcher.
 *  New: API to access headers as `java.time.Instant`.

    compressed file (like a JAR or APK), so compressing its internal data was redundant.

 *  Fix: Call `ProxySelector.connectFailed()` when a connection's initial TCP handshake fails.

 *  Fix: Change the signature of `Dispatcher` to accept a nullable `ExecutorService`. Changing this
    parameter to be non-null was an unintended signature change in OkHttp 4.0.
