HTTPS connection. If you continue to need to connect to webservers
    running SSLv3, you must manually configure your own `ConnectionSpec`.

 *  **OkHttp now offers interceptors.** Interceptors are a powerful mechanism
    that can monitor, rewrite, and retry calls. The [interceptors doc][interceptors] is a full
    introduction to this new API.

 *  New: APIs to iterate and selectively clear the response cache.

* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**.
* How to set **validation constraints** as `maximum_length` or `regex`.
* A very powerful and easy to use **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.

 *  **Form and Multipart bodies are now modeled.** We've replaced the opaque
    `FormEncodingBuilder` with the more powerful `FormBody` and
    `FormBody.Builder` combo. Similarly we've upgraded `MultipartBuilder` into
    `MultipartBody`, `MultipartBody.Part`, and `MultipartBody.Builder`.

            <p>In addition to the traditional activation mechanisms (JDK version, OS properties,
            file existence, etc.), Maven now supports a powerful condition-based activation
            through the {@code condition} field. This new mechanism allows for more flexible
            and expressive profile activation rules.</p>

**Note**: You probably don't need `contextvars`, and you should probably avoid using them. But they are powerful and useful in some advanced scenarios, for example, migrating from code that used Flask's `g` semi-global variable.
