- The RuntimeClass API has been added. This feature is in alpha, and the RuntimeClass feature gate must be enabled in order to use it. The RuntimeClass API resource defines different classes of runtimes that may be used to run containers in the cluster. Pods can select a RuntimeClass to use via the RuntimeClassName field.

- Changed CRI pod log directory from `/var/log/pods/UID` to `/var/log/pods/NAMESPACE_NAME_UID`. ([#74441](https://github.com/kubernetes/kubernetes/pull/74441), [@Random-Liu](https://github.com/Random-Liu))
- `RuntimeClass` has been promoted to beta, and is enabled by default. ([#75003](https://github.com/kubernetes/kubernetes/pull/75003), [@tallclair](https://github.com/tallclair))
