problems. If your service has multiple IP addresses, OkHttp will attempt alternate addresses if the
first connect fails. This is necessary for IPv4+IPv6 and services hosted in redundant data
centers. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate pinning). It can be
configured to fall back for broad connectivity.

 *  Fix: Don't double-compress the public suffix database. OkHttp is usually distributed in a
    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
