 ### Infrastructure
 
 Prior to this release, if you had a module with multiple features, you had to use the `[Feature("your feature id")]` attribute to assign `IShapeTableProvider`, `IDataMigration`, and `IPermissionProvider` to a specific feature of the module that had a feature ID other than the module ID. With [pull-request 15793](https://github.com/OrchardCMS/OrchardCore/pull/15793), this is no longer needed. However, `[Feature("...")]` is still required for the `Startup` class and controllers when you want the controller action to be available only when a specific feature is enabled.
