## 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.

It can be used to tell kubeadm to wait for all control plane components to be ready when running "kubeadm init" or "kubeadm join --control-plane". Currently kubeadm only waits for the kube-apiserver. The "kubeadm join" workflow now includes a new experimental phase called "wait-control-plane". This phase will be marked as non-experimental when WaitForAllControlPlaneComponents becomes GA. Accordingly a "kubeadm init" phase "wait-control-plane" will also be available once WaitForAllControlPlaneComponents...

Kubernetes' default backend storage, etcd, has a new release 3.5.0 and the community embraced it. The new release comes with improvements to the Security, performance, monitoring and developer experience. There are numerous bug fixes to lease objects causing memory leaks, and compact operation causing deadlocks and more. A couple of new features are also introduced like the migration to structured logging and build in log rotation. The release comes with a detailed future roadmap to implement a solution...

LocalPersistentVolume features are beta and enabled by default.  The PersistentVolume NodeAffinity alpha annotation is deprecated and will be removed in a future release. ([#59391](https://github.com/kubernetes/kubernetes/pull/59391), [@msau42](https://github.com/msau42))

* The alpha Accelerators feature gate is deprecated and will be removed in v1.11. Please use device plugins ([https://github.com/kubernetes/enhancements/issues/368](https://github.com/kubernetes/enhancements/issues/368)) instead. They...

- Kubernetes is now built with go 1.20.1 ([#115828](https://github.com/kubernetes/kubernetes/pull/115828), [@cpanato](https://github.com/cpanato)) [SIG Release and Testing]
- Kubernetes is now built with go 1.20.2 ([#116404](https://github.com/kubernetes/kubernetes/pull/116404), [@cpanato](https://github.com/cpanato)) [SIG Release and Testing]

The code which implements them will be removed in a future release, so users of those need to start replacing the deprecated flags with some alternative solutions.

### Software Supply Chain SLSA Level 1 Compliance in the Kubernetes Release Process

There is an open PR ([#48189](https://github.com/kubernetes/kubernetes/pull/48189)) to resolve this issue, but as this issue also exists in 1.6, and as we do not wish to risk release stability by merging it directly prior to a release without sufficient testing, we have decided to defer merging the PR until the next point release for each minor version ([#48190](https://github.com/kubernetes/kubernetes/pull/48190)).
