See the full details in the [changelog](https://www.nutrient.io/guides/web/changelog.md#1.10.0). ### Performance improvements for large documents This release includes performance enhancements when working with documents containing many pages. The thumbnails sidebar and document editor thumbnails now load much faster and more efficiently, making large documents easier to navigate. Additionally, we removed the smooth scrolling animation when the thumbnail sidebar opens, ensuring it immediately displays the thumbnail of the page currently in the viewport. This eliminates the waiting time users previously experienced when opening the sidebar with documents containing hundreds of pages. ### Annotation color and styling improvements This release includes fixes for annotation color handling when using custom color presets. When you configure `annotationToolbarColorPresets`, programmatically created annotations now correctly respect the colors you specify. We also fixed an issue with text annotations with transparent backgrounds when using custom color presets. Annotation presets also now correctly maintain font styles (bold, italic, underline), ensuring that saved presets maintain their intended formatting when restored. ### Print preview improvements Print preview functionality has been improved in DOM mode. Additionally, we fixed some iOS Safari-specific issues in print preview. ### UI and accessibility enhancements This release includes improvements to the user interface and accessibility. Tooltips and aria-labels in the annotations sidebar and comment threads have been enhanced to provide clearer guidance and better screen reader support. We also made improvements in the scrolling behavior for modals. ### Annotation behavior fixes This release resolves several annotation-related issues. We made some fixes in link annotations to improve the clicking behavior. The rendering of text annotations has been improved for rotated pages. We also made some Android-specific improvements to text annotations to prevent data loss during editing. Text and callout annotations have also been improved to prevent overflow beyond page boundaries when editing. ### Document Editor improvements We fixed some issues in custom Document Editor toolbar items with icons. ### Form field and document processing improvements This release enhances form field handling. We fixed some issues in form fields with additional actions. Radio and checkbox options are improved to work even when PDFs have inconsistent option lists. ### Document loading improvements File type detection has been enhanced to correctly handle Content-Type headers that include charset or boundary parameters, improving compatibility with various server configurations. 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#1.10.0).
