 You can also now optionally implement a `canView()` method on your `BuildTask` implementations to restrict accessed for specific tasks even further. This means you can grant access to _some_ tasks to specific users or groups without granting access to _all_ tasks.
 
+### New exception in React forms {#react-forms-exception}
+
+A [`LogicException`](https://www.php.net/manual/en/class.logicexception.php) is now thrown by [`FormSchema::getSchema()`](api:SilverStripe\Forms\Schema::getSchema()) if a react component was not found for a field type.
+
+[warning]
+If your project or a module you're using is currently trying to include a field which doesn't have a react component into a react-rendered form, it will have been silently failing. The form will have been rendering everything except for the field(s) which have no react component.
+
+This will now fail by throwing an exception, which means your form won't render at all until you remove or replace the field(s).
+[/warning]

 ### Other new features
 
 - A new [`SiteTree.hide_pagetypes`](api:SilverStripe\CMS\Model\SiteTree->hide_pagetypes) configuration property has been added. Unlike [`SiteTree.hide_ancestor`](api:SilverStripe\CMS\Model\SiteTree->hide_ancestor) (which has [now been deprecated](#api-silverstripe-cms)), this is an array. This allows you to define all page types that should be hidden in a single configuration property in your yaml configuration.
