    parens, and other characters.
 *  Fix: Relax `FormEncodingBuilder` to support building empty forms.
 *  Fix: Timeouts throw `SocketTimeoutException`, not `InterruptedIOException`.
 *  Fix: Change `MockWebServer` to use the same logic as OkHttp when determining
    whether an HTTP request permits a body.
 *  Fix: `HttpUrl` now uses the canonical form for IPv6 addresses.

 *  Fix: Reverse suppression of connect exceptions. When both a call and its retry fail, we now
    throw the initial exception which is most likely to be actionable.
 *  Fix: Retain interrupted state when throwing `InterruptedIOException`. A single interrupt should
    now be sufficient to break out an in-flight OkHttp call.
 *  Fix: Don't drop a call to `EventListener.callEnd()` when the response body is consumed inside an
    interceptor.
