+### Elemental `TopPage` class names changed {#elemental-top-page}
+
+The class names for the `TopPage` feature in [`dnadesign/silverstripe-elemental`](https://github.com/silverstripe/silverstripe-elemental) did not follow the correct naming convention for Silverstripe CMS. The class names have been changed as follows:
+
+|old name|new name|
+|---|---|
+|`DNADesign\Elemental\TopPage\DataExtension`|`DNADesign\Elemental\Extensions\TopPageElementExtension`|
+|`DNADesign\Elemental\TopPage\FluentExtension`|`DNADesign\Elemental\Extensions\TopPageElementFluentExtension`|
+|`DNADesign\Elemental\TopPage\SiteTreeExtension`|`DNADesign\Elemental\Extensions\TopPageSiteTreeExtension`|
+
+If you reference any of these classes in your project or module, most likely in config if you have [`tractorcow/silverstripe-fluent`](https://github.com/tractorcow/silverstripe-fluent) installed, then you will need to update the references to the new class names.
+
 ### General changes {#api-general}
 
 - [`DataObject::write()`](api:SilverStripe\ORM\DataObject::write()) has a new boolean `$skipValidation` parameter. This can be useful for scenarios where you want to automatically create a new record with no data initially without restricting how developers can set up their validation rules.
