## Version 4.0.0

_2019-06-26_

**This release upgrades OkHttp to Kotlin.** We tried our best to make fast and safe to upgrade
from OkHttp 3.x. We wrote an [upgrade guide][upgrading_to_okhttp_4] to help with the migration and a
[blog post][okhttp4_blog_post] to explain it.

/// tip

It's very common in Python packages to try the best to **avoid breaking changes** in **new versions**, but it's better to be safe, and install newer versions intentionally and when you can run the tests to check everything is working correctly.

///

 *  **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.**
