### [Fast Fallback](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/-builder/fast-fallback/)

Since version 5.0, `OkHttpClient` supports fast fallback, which is our implementation of Happy Eyeballs [RFC 6555](https://datatracker.ietf.org/doc/html/rfc6555).

* `deployments/rollback` is now passed through validation/admission controllers ([#72271](https://github.com/kubernetes/kubernetes/pull/72271), [@jhrv](https://github.com/jhrv))
