It also includes a new option to create annotation variants with the new ink highlighter and arrow tools enabled by default, plus a whole lot more! If you’re maintaining a Server installation, be sure to check out the [2018.5 server migration guide](https://www.nutrient.io/guides/product-archives-and-deprecated-solutions.md). ### API changes - Adds `Configuration#enableServiceWorkerSupport` to not bypass service workers when loading stylesheets inside PSPDFKit for Web. - Adds [`defaultAnnotationPresets`](https://www.nutrient.io/api/web/variables/NutrientViewer.defaultAnnotationPresets.html) for annotation presets. You can read more about customizing annotation presets in our [Customizing the Toolbar](https://www.nutrient.io/guides/web/customizing-the-interface/customizing-the-toolbar.md#annotation-variant-buttons) guide. - Removes `InteractionMode.LAYOUT_CONFIGURATION`. The state of the layout configurator will be no longer be exposed. ### Notable changes - The order of [`defaultToolbarItems`](https://www.nutrient.io/api/web/variables/NutrientViewer.defaultToolbarItems.html) was changed. - New toolbar items for document outline, document annotation sidebar, the `highlighter` variant, and the `arrow` variant were added to the [`defaultToolbarItems`](https://www.nutrient.io/api/web/variables/NutrientViewer.defaultToolbarItems.html). - We fixed an issue with exported and imported XFDF files on rotated pages. - The placement logic of dropdowns has changed, and CSS rules that rely on the HTML structure of the dropdowns might need to be updated.
