- 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]

- In CRD webhook conversion, Kubernetes will now ignore changes to metadata other than for labels and annotations. ([#77743](https://github.com/kubernetes/kubernetes/pull/77743), [@sttts](https://github.com/sttts))
