* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.

Both are equivalent and underneath they are the same, but I would recommend `Union` instead of `Optional` because the word "**optional**" would seem to imply that the value is optional, and it actually means "it can be `None`", even if it's not optional and is still required.

I think `Union[SomeType, None]` is more explicit about what it means.

    `Credentials`.

 *  **OkHttpClient.getFollowProtocolRedirects() renamed to
    getFollowSslRedirects()**. We reserve the word _protocol_ for the HTTP
    version being used (HTTP/1.1, HTTP/2). The old name of this method was
    misleading; it was always used to configure redirects between `https://` and
    `http://` schemes.

 *  The `AndroidLogging` class is no longer necessary. `LoggingEventListener` and
    `HttpLoggingInterceptor` write to logcat by default.

The rest of this release is our highest-quality release yet. Though we continue to use the word
_alpha_ in the version name, the only unstable thing in it is some non-final APIs tagged
`@ExperimentalOkHttpApi`. You can safely use this release in production.
