+You can opt in to including a comment on all ORM queries indicating where the query was executed by setting the [DBQueryBuilder.trace_query_origin](api:SilverStripe\ORM\Connect\DBQueryBuilder->trace_query_origin) configuration property or the `SS_TRACE_DB_QUERY_ORIGIN` environment variable to `true`.
+
+Note that the environment variable, if set, will take precedence over the configuration property value.

 - The assets admin section now respects the [`Upload_Validator.default_max_file_size`](api:SilverStripe\Assets\Upload_Validator->default_max_file_size) configuration if [`AssetAdmin.max_upload_size`](api:SilverStripe\AssetAdmin\Controller\AssetAdmin->max_upload_size) has not been explicitly set for your project. Previously, asset admin would ignore `Upload_Validator.default_max_file_size` and just use the PHP `upload_max_filesize` ini configuration by default.
 - Redirector pages with a link to a missing or unpublished page/file will now return a 404 response. You can revert to the previous behaviour by setting the [`RedirectorPageController.missing_redirect_is_404`](api:SilverStripe\CMS\Model\RedirectorPageController->missing_redirect_is_404) configuration property to `false`.
