 ## Breaking changes
+#### v13.2.0
+Introduced Razor Class Library support to serve static files for Engage, removing physical back-office-, views and assets files from development projects.
+While this is not considered a breaking change, it is recommended to remove these folders from your project to avoid any potential conflicts in the future.
+The following folders should be manually removed from your project upon updating:
+  * `App_Plugins\Umbraco.Engage`
+  * `Assets\Umbraco.Engage`
+  * `Views\Partials\Umbraco.Engage`
+
+Health checks have been added to verify whether these folders are present in your project. If they are, you will receive a warning in the Health Check dashboard.
+
+Please note that this is only for the `Umbraco.Engage` package. Any addons like `Umbraco.Engage.Forms` will still have physical files in your project in this version.
+
+#### v13.0.0 (Umbraco Engage Launch)
+
+Umbraco Engage contains a number of breaking changes from the previous uMarketingSuite product.
+
+See the [Migrate from uMarketingSuite](migrate-from-umarketingsuite) for full details.
