### CRI ### CRI
This version of containerd is validated against v1.15, but it is also compatible with Kubernetes v1.12+. (See [more details](https://github.com/containerd/cri#support-metrics) about support metrics)
#### Features #### Features
* **Supported per-pod containerd shim.** The `io.containerd.runc.v2` runtime is fully validated and ready to be used in production. This helps minimizing per-pod resource overhead. Note that `io.containerd.runtime.v1.linux` is still the default runtime.
