requests, responses, headers, and calls. It uses modern Java patterns like
immutability and chained builders. The API now offers asynchronous callbacks
in addition to synchronous blocking calls.

#### API Changes

 *  **New Request and Response types,** each with their own builder. There's also
    a `RequestBody` class to write the request body to the network and a

### [Fast Fallback](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-ok-http-client/-builder/fast-fallback)

Since version 5.0, `OkHttpClient` supports fast fallback, which is our implementation of Happy Eyeballs [RFC 6555](https://datatracker.ietf.org/doc/html/rfc6555).
