+The fourth major release of containerd comes over 9 months after the previous
+major release and covers a period of both significant project growth and
+further stabilization. Similar to previous releases, the number of API changes
+are small and, as always, backwards compatible. The growing ecosystem of plugins
+and users have driven improvements to make containerd more configurable, usable,
+and pluggable. On Windows, this release brings a new runtime utilizing the shim
+API. For clients, there are many new features and improvements completely
+implemented in the client libraries without requiring daemon upgrade.
