This release consists of 46 enhancements: fifteen enhancements have graduated to stable, fifteen enhancements are moving to beta, and thirteen enhancements are entering alpha. Also, two features have been deprecated, and the [dockershim has been removed](https://kubernetes.io/blog/2022/02/17/dockershim-faq/).
## Major Themes
### Dockershim Removed from kubelet
After an initial deprecation in v1.20, the dockershim has been removed from the kubelet. From v1.24 and up, if you are currently relying on Docker Engine as your container runtime, you will need to either use one of the other supported runtimes (such as containerd or CRI-O) or use cri-dockerd. For more information about ensuring your cluster is ready for this removal, please see [this guide](/blog/2022/03/31/ready-for-dockershim-removal/).
