- `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))

- 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....

 that does not depend on mutable selectors.

 - Extended Resources are fully-qualified resource names outside the
 `kubernetes.io` domain. Extended Resource quantities must be integers.
 You can specify any resource name of the form `[aaa.]my-domain.bbb/ccc`
