Refer to the [changelog](https://www.nutrient.io/guides/web/changelog.md#1.1.0) for full details. ### New API: NutrientViewer.build() `NutrientViewer.build()` performs processing via the Nutrient backend [Build API](https://www.nutrient.io/api/reference/public/#tag/Build-API). Example usage: ```js NutrientViewer.build( // Authorize request. { jwt: authPayload.jwt }, // Instructions for the processing request. { parts: [ // Use first input as the first part of the final document. { file: "document" }, // Use a sample DOCX document served from a URL as the second part of the final document. { file: { url: "https://www.nutrient.io/api/assets/downloads/samples/docx/document.docx" } } ] }, // Inputs required by the request. These will be uploaded with the request. The remote file served from URL does not need to be uploaded. [{ name: "document", content: document }] ); ``` ### Performance and UX improvements - Enhanced memory efficiency when decoding large documents, enabling better handling of resource-intensive PDFs. - Improved UX when selecting text from right to left, particularly with sentence-ending words. - Callout annotation text overflow, bounding box, and arrow positioning improvements. - Updated key dependencies: React (18.3.1) and react-intl (7.1.6). Minimum Document Engine version required: [1.5.6](https://www.nutrient.io/guides/document-engine/changelog.md#1.5.6) For a complete list of changes, bug fixes, and performance improvements, refer to the [changelog](https://www.nutrient.io/guides/web/changelog.md#1.1.0).
