    certain bad routes indefinitely; now we only track the ones that could be necessary.
 *  Fix: Defer proxy selection until a proxy is required. This saves calls to `ProxySelector` on
    calls that use a pooled connection.


## Version 4.3.1

 *  Fix: Don't crash with a `NullPointerException` when a web socket is closed before it connects.

 * connection the client has many options:
 *
 *  * **HTTP proxy:** a proxy server may be explicitly configured for the client. Otherwise, the
 *    [proxy selector][java.net.ProxySelector] is used. It may return multiple proxies to attempt.
 *  * **IP address:** whether connecting directly to an origin server or a proxy, opening a socket

 *  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

    behavior was surprising because OkHttp was disregarding the user's specified configuration. If
    you need to customize proxy fallback behavior, implement your own `java.net.ProxySelector`.

 *  Fix: Support TLSv1.3 on devices that support it.

 *  Fix: Share pooled connections across equivalent `OkHttpClient` instances. Previous releases had
