- Fixed a bug where `kubectl` drain would consider a pod as having been deleted if an error occurs while calling the API. ([#122574](https://github.com/kubernetes/kubernetes/pull/122574), [@brianpursley](https://github.com/brianpursley))

  Drop support for the deprecated --delete-local-data from kubectl drain, users should use --delete-emptydir-data, instead. ([#125842](https://github.com/kubernetes/kubernetes/pull/125842), [@soltysh](https://github.com/soltysh)) [SIG CLI]
