## Version 3.0.0-RC1

_2016-01-02_

OkHttp 3 is a major release focused on API simplicity and consistency. The API
changes are numerous but most are cosmetic. Applications should be able to
upgrade from the 2.x API to the 3.x API mechanically and without risk.

Because the release includes breaking API changes, we're changing the project's
package name from `com.squareup.okhttp` to `okhttp3`. This should make it

Al considerar estos conceptos, podrás **evaluar y diseñar** la mejor manera de implementar **tus propias APIs**.

En los próximos capítulos, te daré más **recetas concretas** para implementar aplicaciones de FastAPI.

Pero por ahora, revisemos estas importantes **ideas conceptuales**. Estos conceptos también se aplican a cualquier otro tipo de API web. 💡

## Seguridad - HTTPS { #security-https }

    protected String[] acceptedRoles = { "admin" };

    /**
     * Default constructor.
     * Initializes the API manager with the admin server path prefix.
     */
    public SearchEngineApiManager() {
        super();
        setPathPrefix(ADMIN_SERVER);
    }

    /**
     * Registers this API manager with the web API manager factory.

}
```

Further examples are on the [OkHttp Recipes page][recipes].


Requirements
------------

OkHttp works on Android 5.0+ (API level 21+) and Java 8+.

On Android, OkHttp uses [AndroidX Startup][androidx_startup]. If you disable the initializer in the manifest,
then apps are responsible for calling `OkHttp.initialize(applicationContext)` in `Application.onCreate`.

Essa "espera" 🕙 é medida em microssegundos, mas ainda assim, somando tudo, é um monte de espera no final.

Por isso que faz bastante sentido utilizar código assíncrono ⏸🔀⏯ para APIs web.

Esse tipo de assincronicidade é o que fez NodeJS popular (embora NodeJS não seja paralelo) e essa é a força do Go como uma linguagem de programação.

E esse é o mesmo nível de performance que você tem com o **FastAPI**.

 * <h3>Relationship to {@code Ordering}</h3>
 *
 * <p>In light of the significant enhancements to {@code Comparator} in Java 8, the overwhelming
 * majority of usages of {@code Ordering} can be written using only built-in JDK APIs. This class is
 * intended to "fill the gap" and provide those features of {@code Ordering} not already provided by
 * the JDK.
