+### Release Notes for [3.11.0](https://github.com/laminas/laminas-servicemanager/milestone/21)
 
-- Nothing.
+### Changed
+
+This release makes a significant change, but one that is currently fully backwards-compatible.
+
+The package now **replaces** the `container-interop/container-interop` package (versions 1.2.0 and later), and makes all container-interop interfaces aliases of PSR-11 interfaces via an autoloader rule. The net effect is that all typehints in laminas-servicemanager classes (both for parameter typehints as well as implementations) are now against PSR-11 interfaces, while still retaining backwards compatibility with container-interop.
+
+We will provide tooling in an upcoming release to allow end-users to update any classes they have that typehint against or implement container-interop interfaces to switch to PSR-11 interfaces instead. After that tooling is available, we will do another release that drops the interface aliases entirely.
