The Kubernetes version matrix represents the versions of containerd which are recommended for a Kubernetes release. Any actively supported version of containerd may receive patches to fix bugs encountered in any version of Kubernetes, however, our recommendation is based on which versions have been the most thoroughly tested. See the Kubernetes test grid for the list of actively tested versions. Kubernetes only supports n-3 minor release versions and containerd will ensure there is always a supported version of containerd for every supported version of Kubernetes.

| 1.21 | 1.5.0+ | v1alpha2 |
