  before and after upgrading to convert them to StatefulSets. ([docs](http://kubernetes.io/docs/tasks/manage-stateful-set/upgrade-pet-set-to-stateful-set/)) ([#35663](https://github.com/kubernetes/kubernetes/pull/35663), [@janetkuo](https://github.com/janetkuo))

* Fix issue with kubectl annotate when --resource-version is provided. ([#29319](https://github.com/kubernetes/kubernetes/pull/29319), [@juanvallejo](https://github.com/juanvallejo))
