*  Fix: Don't re-encode `+` as `%20` in encoded URL query strings. OkHttp
    prefers `%20` when doing its own encoding, but will retain `+` when that is
    provided.
 *  Fix: Enforce that callers call `WebSocket.close()` on IO errors. Error
    handling in WebSockets is significantly improved.
 *  Fix: Don't use SPDY/3 style header concatenation for HTTP/2 request headers.
    This could have corrupted requests where multiple headers had the same name,

 *   <li>As a convenience, the {@code main} of this class (JSR166TestCase) runs all JSR166 unit
 *       tests.

- Reverted the `EventedPLEG` feature (beta, but disabled by default) back to alpha due to a known issue.
   ([#122697](https://github.com/kubernetes/kubernetes/pull/122697), [@pacoxu](https://github.com/pacoxu))
- Used `errors.Is()` to handle errors returned by `LookPath()`.
   ([#122600](https://github.com/kubernetes/kubernetes/pull/122600), [@lzhecheng](https://github.com/lzhecheng))
- kube-proxy: Fixed `LoadBalancerSourceRanges` not working for `nftables` mode.

- Kubeadm: avoid panicing if the user has malformed the kubeconfig in the cluster-info config map to not include a valid current context. Include proper validation at the appropriate locations and throw errors instead.

* The error handling behavior of `pkg/client/restclient.Result` has changed.  Calls to `Result.Raw()` will no longer parse the body, although they will still return errors that react to `pkg/api/errors.Is*()` as in previous releases.  Callers of `Get()` and `Into()` will continue to receive errors that are parsed from the body if the kind and apiVersion of the body match the `Status` object.

- Fixes a regression in kube-apiserver causing 500 errors from the `/readyz` endpoint ([#93643](https://github.com/kubernetes/kubernetes/pull/93643), [@ialidzhikov](https://github.com/ialidzhikov)) [SIG API Machinery]

- The `kube-apiserver` will now expose four new metrics to inform about errors on the clusterIP and nodePort allocation logic. ([#120843](https://github.com/kubernetes/kubernetes/pull/120843), [@aojea](https://github.com/aojea))
