With the introduction of Image Documents, the web Standalone `Configuration#pdf` option has been deprecated in favor of `Configuration#document`. As we are simply renaming the option, the behavior for PDFs remains the same, and no additional changes are required. The old option will be removed in 2020.3. See the API documentation for [more details](https://www.nutrient.io/api/web/interfaces/Configuration.html#document). - Properties deprecated in `2020.1` have been removed: - `NutrientViewer.I18n#localeData` — This property stopped working in `2020.1`, and a deprecation warning was shown when used. The warning will no longer be shown, and the property is removed, so it will just return `undefined` if accessed. Refer to the [2020.1 migration guide](https://www.nutrient.io/guides/web/release-notes/2020-1.md) for details on how to migrate from this property. - `NutrientViewer.Annotations.RectangleAnnotation#cloudyBorderInsetRect` and `NutrientViewer.Annotations.EllipseAnnotation#cloudyBorderInsetRect` could still be used after `2020.1` with a warning. These properties will no longer work, they will return `undefined` if accessed, and no warning will be shown. Refer to the [2020.1 migration guide](https://www.nutrient.io/guides/web/release-notes/2020-1.md) and the API documentation on [`NutrientViewer.Annotations.RectangleAnnotation#cloudyBorderInset`](https://www.nutrient.io/api/web/classes/NutrientViewer.Annotations.RectangleAnnotation.html#cloudyborderinset) and [`NutrientViewer.Annotations.EllipseAnnotation#cloudyBorderInset`](https://www.nutrient.io/api/web/classes/NutrientViewer.Annotations.EllipseAnnotation.html#cloudyborderinset) for details on how to migrate from these properties. If you use PSPDFKit Server, make sure you read the [2020.2 migration guide](https://www.nutrient.io/guides/product-archives-and-deprecated-solutions.md).
