 * ## Why another URL model?
 *
 * Java includes both [java.net.URL][URL] and [java.net.URI][URI]. We offer a new URL
 * model to address problems that the others don't.
 *
 * ### Different URLs should be different
 *
 * Although they have different content, `java.net.URL` considers the following two URLs

 * chain. The chain terminates in a self-signed "root" certificate. Signing certificates in the
 * middle of the chain are called "intermediates". Organizations that offer certificate signing are
 * called certificate authorities (CAs).
 *
 * Browsers and other HTTP clients need a set of trusted root certificates to authenticate their

     * on what they know about the particular Joiner instances the calls are performed on.
     *
     * (In addition to useForNull, we also offer skipNulls. It, too, tolerates null inputs, but its
     * tolerance is implemented differently: Its implementation avoids calling this toString(Object)
     * method in the first place.)

    vulnerability, OkHttp no longer offers SSLv3 when negotiation an
    HTTPS connection. If you continue to need to connect to webservers
    running SSLv3, you must manually configure your own `ConnectionSpec`.

This is our first stable release of OkHttp since 2023. Here's the highlights if you're upgrading
from OkHttp 4.x:

**OkHttp is now packaged as separate JVM and Android artifacts.** This allows us to offer
platform-specific features and optimizations. If your build system handles [Gradle module metadata],
this change should be automatic.

**This release candidate turns on web socket compression.**

The [spec][rfc_7692] includes a sophisticated mechanism for client and server to negotiate
compression features. We strive to offer great performance in our default configuration and so we're
making compression the default for everyone starting with this release candidate.
