- The Pod API field `.spec.schedulingGates[*].name` now requires qualified names (like `example.com/mygate`), matching validation for names of `.spec.readinessGates[*].name`. Any uses of the alpha scheduling gate feature prior to 1.27 that do not match that validation must be renamed or deleted before upgrading to 1.27....

- `kubeadm`: will now throw warnings instead of errors for deprecated feature gates. ([#118270](https://github.com/kubernetes/kubernetes/pull/118270), [@pacoxu](https://github.com/pacoxu))
- `kubectl events --for` will also support fully qualified names such as replicasets.apps,
  etc. ([#117034](https://github.com/kubernetes/kubernetes/pull/117034), [@ardaguclu](https://github.com/ardaguclu))
