- Added support for kube-proxy iptables mode to track packets that were wrongfully marked invalid by conntrack and subsequently dropped by introducing `kubeproxy_iptables_ct_state_invalid_dropped_packets_total` metric. ([#122812](https://github.com/kubernetes/kubernetes/pull/122812), [@aroradaman](https://github.com/aroradaman)) [SIG Instrumentation, Network and Testing]

- Fixed [121094](https://github.com/kubernetes/kubernetes/issues/121094) by re-introducing the readiness predicate for `externalTrafficPolicy: Local` services. ([#121116](https://github.com/kubernetes/kubernetes/pull/121116), [@alexanderConstantinescu](https://github.com/alexanderConstantinescu))

- DRA API: resource.k8s.io/v1alpha3 now only contains DeviceTaintRule. All other types got removed because they became obsolete when introducing the v1beta1 API in 1.32.

- Kubernetes is now built with Go 1.20.11 ([#121812](https://github.com/kubernetes/kubernetes/pull/121812), [@cpanato](https://github.com/cpanato)) [SIG Release and Testing]
