## Changelog since v1.23.0

## Major Themes

### Dockershim Removed from kubelet

After its deprecation in v1.20, the dockershim component has been removed from the kubelet.
From v1.24 onwards, you will need to either use one of the other [supported runtimes](https://kubernetes.io/docs/setup/production-environment/container-runtimes/) (such as containerd or CRI-O)

- Hyperkube will now be available in a new Github repository and will not be included in the kubernetes release from 1.17 onwards ([#83454](https://github.com/kubernetes/kubernetes/pull/83454), [@dims](https://github.com/dims))

  by default. The CSI drivers can make use of the `secretRef` values passed in `NodeExpansion`
  request optionally sent by the CSI Client from this release onwards. ([#121303](https://github.com/kubernetes/kubernetes/pull/121303), [@humblec](https://github.com/humblec))
