- The resource/v1alpha3.ResourceSliceList filed which should have been named "metadata" but was instead named "listMeta" is now properly "metadata". ([#126749](https://github.com/kubernetes/kubernetes/pull/126749), [@thockin](https://github.com/thockin)) [SIG API Machinery]

- The feature gate "SkipReadOnlyValidationGCE" has been removed.  This gate has been active for 2 releases with no reports of issues (and was such a niche thing, we didn't expect any). ([#124210](https://github.com/kubernetes/kubernetes/pull/124210), [@thockin](https://github.com/thockin))

- The `--bind-address` parameter in kube-proxy is misleading, no port is opened with this address. Instead it is translated internally to "nodeIP". The nodeIPs for both families are now taken from the Node object if `--bind-address`...

### API Change

- Fixes a regression in openapi descriptions of PodIP.IP  and HostIP.IP fields to mark the fields used as keys in those lists as required. ([#126666](https://github.com/kubernetes/kubernetes/pull/126666), [@thockin](https://github.com/thockin)) [SIG API Machinery]

### Feature

- Kubernetes is now built with go 1.22.6 ([#126970](https://github.com/kubernetes/kubernetes/pull/126970), [@cpanato](https://github.com/cpanato)) [SIG Release and Testing]
