# Kubernetes 1.24

## Breaking Change

### Transition to Charmhub

https://charmhub.io/

Starting with this release, charms and bundles will be published to Charmhub instead of the Charm Store.

## Important Change

### Calico is now the default CNI

The charmed-kubernetes and kubernetes-core reference bundles have been updated to use Calico for pod networking instead of Flannel. We recommend Calico as the default CNI choice for all new deployments due to the rich set of advanced networking features that it provides.

While we do recommend Calico as the default choice, we will continue to support new and existing deployments that use Flannel as well.

### Docker support deprecated

The default container runtime in Charmed Kubernetes has been containerd for some time. The Docker container runtime is no longer supported.
