[`AnnotationManager.setSnapDefaultOptions`](https://sdk.apryse.com/api/web/Core.AnnotationManager.html#setSnapDefaultOptions__anchor) allows you to change the indicator size, color and snapping threshold. * Added [`DistanceMeasurementCreateTool.setLeaderLineDefaultOptions`](https://sdk.apryse.com/api/web/Core.Tools.DistanceMeasurementCreateTool.html#setLeaderLineDefaultOptions) to control whether leader lines are enabled, whether they should be created by default and what their length should be when annotations are created using the tool. * Added support for point snapping when adjusting the points of annotations that had been created with a tool that enabled snapping * Added support for editing, adding and removing links when in content editing mode * Added [`Core.MeasurementManager`](https://sdk.apryse.com/api/web/Core.MeasurementManager.html) with APIs related to annotation and tool style syncing * Added new APIs [`SignatureWidgetAnnotation.getAssociatedSignatureAnnotation`](https://sdk.apryse.com/api/web/Core.Annotations.SignatureWidgetAnnotation.html#getAssociatedSignatureAnnotation__anchor) and [`SignatureWidgetAnnotation.setAssociatedSignatureAnnotation`](https://sdk.apryse.com/api/web/Core.Annotations.SignatureWidgetAnnotation.html#setAssociatedSignatureAnnotation__anchor) to manage the `annot` property instead of having only the property itself * Added new APIs [`DocumentViewer.getPDFCoordinatesFromMouseEvent`](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#getPDFCoordinatesFromMouseEvent__anchor) and [`DocumentViewer.getViewerCoordinatesFromMouseEvent`](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#getViewerCoordinatesFromMouseEvent__anchor) to make converting from mouse coordinates easier * Added `isSmoothScroll` option for [`AnnotationManager.jumpToAnnotation`](https://sdk.apryse.com/api/web/Core.AnnotationManager.html#jumpToAnnotation) API for scrolling the viewer smoothly when jumping to an annotation * Added `isSmoothScroll` parameter to [`DocumentViewer.setCurrentPage`](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#setCurrentPage) for scrolling the viewer smoothly when setting the current page * Updated the `DistanceMeasurementCreateTool` behavior so that annotations created will not have their text displayed upside down. * Added new API [`Core.enableWorkerLogs`](https://sdk.apryse.com/api/web/Core.html#.enableWorkerLogs__anchor) to turn on PDF worker logs which can be useful for debugging issues * Added new API [`Document.setTextExtractorProcessingFlags`](https://sdk.apryse.com/api/web/Core.Document.html#setTextExtractorProcessingFlags__anchor) which lets you change the way the text is processed and extracted from the document * Added support for automatically setting the filename of the document if the `Content-Disposition` header was set * Added grayscale mode APIs on `DocumentViewer`: [`enableGrayscaleMode`](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#enableGrayscaleMode__anchor), [`disableGrayscaleMode`](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#disableGrayscaleMode__anchor), [`enableGrayscaleAnnotationsMode`](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#enableGrayscaleAnnotationsMode__anchor) and [`disableGrayscaleAnnotationsMode`](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#disableGrayscaleAnnotationsMode__anchor) * Added support for handling internal links inside an office document ### Fixes * Fixed issue that when deleting a page, the bookmark of the deleted page still shows * Fixed issue that with calling `extractPages` with page number greater than the page count and `loadAsPDF` true * Fixed issue where measurement arrow tips would slightly poke past leader lines * Fixed issue where warning is displayed if full API is enabled and the document loaded is not a PDF * Fixed issue where automatic linkifying of text didn't work if the link was uppercase * Fixed issue where setting a custom external path for office documents wasn't applied correctly * Fixed issue with
