 > **CFN Resources:** All classes with the `Cfn` prefix in this module ([CFN Resources](https://docs.aws.amazon.com/cdk/latest/guide/constructs.html#constructs_lib)) are always stable and safe to use.
 
-> **Developer Preview:** Higher level constructs in this module that are marked as developer preview have completed their phase of active development and are looking for adoption and feedback. While the same caveats around non-backward compatible as Experimental constructs apply, they will undergo fewer breaking changes. Just as with Experimental constructs, these are not subject to the [Semantic Versioning](https://semver.org/) model and breaking changes will be announced in the release notes.
+> **Stable:** Higher level constructs in this module that are marked stable will not undergo any breaking changes. They will strictly follow the [Semantic Versioning](https://semver.org/) model.
