This release requires changes to the server as well. Check out our [server migration guides](https://www.nutrient.io/guides/product-archives-and-deprecated-solutions.md) to learn more. ## Destroy API `Instance#destroy` is deprecated in favor of the newly added `NutrientViewer.destroy` API: ### ES6+ ```js // Change this… instance.destroy(); // …to this NutrientViewer.unload(instance); ``` ### JAVASCRIPT ```js // Change this… instance.destroy(); // …to this NutrientViewer.unload(instance); ``` ## Changes to CSS classes We changed a few CSS classes to be more consistent with the general styling. This mainly affects the selectors for note annotation icons: | Old class | New class | | -------------------------------------------- | -------------------------------------------- | | `PSPDFKit-Note-Annotation-Icon-comment` | `PSPDFKit-Note-Annotation-Icon-Comment` | | `PSPDFKit-Note-Annotation-Icon-rightPointer` | `PSPDFKit-Note-Annotation-Icon-RightPointer` | | `PSPDFKit-Note-Annotation-Icon-rightArrow` | `PSPDFKit-Note-Annotation-Icon-RightArrow` | | `PSPDFKit-Note-Annotation-Icon-check` | `PSPDFKit-Note-Annotation-Icon-Check` | | `PSPDFKit-Note-Annotation-Icon-circle` | `PSPDFKit-Note-Annotation-Icon-Circle` | | `PSPDFKit-Note-Annotation-Icon-cross` | `PSPDFKit-Note-Annotation-Icon-Cross` | | `PSPDFKit-Note-Annotation-Icon-insert` | `PSPDFKit-Note-Annotation-Icon-Insert` | | `PSPDFKit-Note-Annotation-Icon-newParagraph` | `PSPDFKit-Note-Annotation-Icon-NewParagraph` | | `PSPDFKit-Note-Annotation-Icon-note` | `PSPDFKit-Note-Annotation-Icon-Note` | | `PSPDFKit-Note-Annotation-Icon-paragraph` | `PSPDFKit-Note-Annotation-Icon-Paragraph` | | `PSPDFKit-Note-Annotation-Icon-help` | `PSPDFKit-Note-Annotation-Icon-Help` | | `PSPDFKit-Note-Annotation-Icon-star` | `PSPDFKit-Note-Annotation-Icon-Star` | | `PSPDFKit-Note-Annotation-Icon-key` | `PSPDFKit-Note-Annotation-Icon-Key` | ## Printing We changed the default printing mode from `PrintMode.EXPORT_PDF` to `PrintMode.DOM`. This should not cause issues with existing setups. Check out the [printing guide](https://www.nutrient.io/guides/web/features/printing.md) to learn about the differences.
