As of {product-title} 4.14, {product-title} uses Linux control group version 2 (cgroup v2) in your cluster. If you are using cgroup v1 on {product-title} 4.13 or earlier, migrating to {product-title} {product-version} will not automatically update your cgroup configuration to version 2. A fresh installation of {product-title} 4.14 or later will use cgroup v2 by default. However, you can enable Linux control group version 1 (cgroup v1) upon installation. Enabling cgroup v1 in {product-title} disables all cgroup v2 controllers and hierarchies in your cluster.
You can switch between cgroup v1 and cgroup v2, as needed, by editing the node.config object. For more information, see "Configuring the Linux cgroup on your nodes" in the "Additional resources" of this section.
