 ### New Proxy Plugins
 
 A new proxy plugin configuration has been added to allow external snapshotters

+### Managed /opt directory
+
+A new `Install` method on the containerd client allows users to publish host level
+binaries using standard container build tooling and container distribution tooling
+to download containerd related binaries on their systems.
+
+This can be used for v2 runtime authors to get their runtime shims on an existing
+containerd system. It can also be used to install `runc` and other related tools.
+
+```bash
+> ctr content fetch docker.io/crosbymichael/runc:latest
+> ctr install docker.io/crosbymichael/runc:latest
