 *  **RC4 cipher suites are no longer supported by default.** To connect to
    old, obsolete servers relying on these cipher suites, you must create a
    custom `ConnectionSpec`.

 *  **Beta WebSockets support.**. The `okhttp-ws` subproject offers a new
    websockets client. Please try it out! When it's ready we intend to include
    it with the core OkHttp library.

 *  **Okio updated to 1.3.0.**

The main point is, **none** of these are **rules written in stone** that you have to blindly follow. You can use these ideas to **evaluate your own use case** and decide what is the best approach for your system, checking out how to manage the concepts of:

* Security - HTTPS
* Running on startup
* Restarts
* Replication (the number of processes running)
* Memory
* Previous steps before starting
