Enhancements

Annotations and Redactions: These features are now consolidated into dedicated panels for better accessibility and organization.

Annotation Toolbar:

Annotations are no longer available as individual actions in the top panel. Instead, they are accessed through a new Annotation Menu button

Upon selection, the annotation bar displays as shown below, containing all configured annotations. Desired annotations can be selected from this bar and applied to the documents.

The list of annotation beans in this toolbar can be configured using the property: toolbar.annotation.buttons.beanNames.

• topPanel.section.right.buttons.beanNames

Default values for these properties in NEV are as follows:

topPanel.section.left.buttons.beanNames=fullscreenButton, showAllAnnotationsButton, refreshAnnotation, showAllAnnotationsAndRotationsButton, addStickyNoteAnnotationButton,annotationCreationOpenCreation, documentBuilderButton, redactCompletionButton

topPanel.section.middle.buttons.beanNames=firstPageButton,previousPageButton,pageNavigation,nextPageButton,lastPageButton,zoomBox,zoomSelectableDropdown,rotateSelectableDropdown,cropBoxButton,selectAllTextDocument,multiViewTools

topPanel.section.right.buttons.beanNames=searchBox,printMenu,downloadMenu,imageProcessingMenu,saveDirtyAnnotations

Make the desired changes to specific deployment instances accordingly.

Configuring Annotation Bar:

The list of beans in the annotation bar can be configured using the property: toolbar.annotation.buttons.beanNames. By default, NEV includes all possible beans in this property:

toolbar.annotation.buttons.beanNames=addStrikethroughTextAnnotationButton,addUnderlineTextAnnotationButton,addFreeTextAnnotationButton,addHighlightTextAnnotationButton,addHighlightRectangleAnnotationButton,addHighlightCircleAnnotationButton,addPolygonAnnotationButton,addPolylineAnnotationButton,addFreehandAnnotationButton,addArrowAnnotationButton,addArrowDistanceAnnotationButton,addStampAnnotationButton,addSoundAnnotationButton

Refer to the following migration guides for UI and rendition changes provided by Arender. This provides changes in the list of properties for their versions of 4.x to 2023.x Ensure the applicable property updates are performed in specific deployment instances respectively.

Deployment Note

For existing instances configured in HA mode, follow these steps when upgrading to NEV 2023.x from 2.x:

1. Disable HA mode.
2. Update the version.
3. Re-enable HA mode.

This step-by-step approach is necessary because the Hazelcast instance needs to be redeployed to avoid serialization errors during a direct upgrade to the newer version.
