## Known Issues

- Concurrently joining control-plane nodes does not work as expected in kubeadm 1.15.0. The feature was planned for release in 1.15.0, but a fix may  come in a follow up patch release.

- Switched intstr.Type to sized integer to follow API guidelines and improve compatibility with proto libraries ([#83956](https://github.com/kubernetes/kubernetes/pull/83956), [@liggitt](https://github.com/liggitt))

* hollow-node do not use remote CRI anymore ([#86425](https://github.com/kubernetes/kubernetes/pull/86425), [@jkaniuk](https://github.com/jkaniuk))
* hollow-node use fake CRI ([#85879](https://github.com/kubernetes/kubernetes/pull/85879), [@gongguan](https://github.com/gongguan))



# v1.18.0-alpha.1

- 'Promoted `cronjob_job_creation_skew` metric to stable to follow the cronjob v2 controller,
  the following metrics had their name updated to match metrics API guidelines:
    - `cronjob_job_creation_skew_duration_seconds` -> `job_creation_skew_duration_seconds`.' ([#113008](https://github.com/kubernetes/kubernetes/pull/113008), [@soltysh](https://github.com/soltysh))

### Ephemeral Containers Graduate to Stable

- Set ProcMountType feature to disabled by default, to follow the lead of UserNamespacesSupport (which it relies on). ([#126291](https://github.com/kubernetes/kubernetes/pull/126291), [@haircommander](https://github.com/haircommander)) [SIG Node]

- Kubectl: add `LAST RESTART` column to `kubectl get pods` output. ([#100142](https://github.com/kubernetes/kubernetes/pull/100142), [@Ethyling](https://github.com/Ethyling))
- Kubemark's hollow-node will now print flags before starting. ([#101181](https://github.com/kubernetes/kubernetes/pull/101181), [@mm4tt](https://github.com/mm4tt))
