Version 12.0.0 Changelog (2026-07-08)

WebViewer Core

The WebViewer Core changelog covers low-level API, engine, and infrastructure changes that power the Web SDK.

New

DOCX Editor

  • Added experimental Core.compareDocx API for comparing two DOCX files.
  • Added acceptTrackedChanges and rejectTrackedChanges batch APIs to TrackedChangeManager for efficiently accepting or rejecting multiple tracked changes in a single operation.
  • Updated the trackedChangesUpdated event to fire with a (trackedChange, action) payload, where action is one of the new TrackedChangeUpdateAction enum values (ADD, MODIFY, DELETE).
  • Removed deprecated DOCX Editor public APIs that were scheduled for removal in v12.0. These APIs were superseded by TrackedChangeManager and other internal APIs.
  • Added selectTrackedChange API and trackedChangeSelected document event that enables programmatic selection of tracked changes and notification of selection state changes.
  • Added navigateToTrackedChange API to TrackedChangeManager that moves the cursor to a tracked change and scrolls it into view. Deprecated moveCursorToTrackedChange to be replaced by new API.

DocumentViewer

  • Removed deprecated DocumentViewer read-only mode APIs and the related readOnlyModeChanged event from the public DocumentViewer API.

Embedded JavaScript

  • Replaced the embedded PDF JavaScript iframe/eval runtime with a SandboxJS-based runtime for improved isolation and continued support for form events, global state, and async PDF JavaScript APIs.

FreeText

  • Moved disableEnterKeypress and enableEnterKeypress to the RichTextEditor namespace.
  • Added EditBoxManager.getEditor.
  • Updated setEditMode to no longer return a promise.

Spreadsheet Editor

  • Added support for loading XLS and CSV files.
  • Added public Chart and ChartManager APIs for programmatic chart interaction, including methods to get, select, move, and resize charts.
  • Added a changeType property to the dataChanged event that indicates the type of change.
  • Migrated Workbook and SpreadsheetEditorClipboard instances to SpreadsheetEditorManager, exposing them via getWorkbook() and getSpreadsheetEditorClipboard().

Widgets

  • Added support for rendering appearances for checkbox widgets.
  • Added support for rendering appearances for text widgets.
  • Added reason, location, and contactInfo options to Core.AnnotationManager.sign so signing apps can embed signer metadata in the signed PDF without dropping down to PDFNet.
  • Deprecated the isSignedDigitally API.

Fixes

  • Fixed an issue where distance measurements in fractional-foot format could display incorrect comma placement for values of 100 ft or greater.

Signatures

Spreadsheet Editor

  • Fixed an issue where undoing sheet deletion showed charts on the wrong sheet.
  • Fixed an issue where undo didn't work after renaming a sheet.
  • Fixed an issue where chart resizing caused inconsistent size changes.
  • Fixed an issue where chart selection handles would become offset from the chart after zooming and switching sheets.
  • Fixed an issue where deleting the active sheet would not render charts on the new sheet correctly.
  • Fixed an issue where the canvas of a selected chart would sometimes appear behind other charts during move or resize operations.

Text selection

  • Fixed an issue where search highlights and text selection rectangles could appear on incorrect glyphs for right-to-left (RTL) and bidirectional text in XOD and Office documents.

Workers

  • Fixed an issue where workers could remain alive after WebViewer was unmounted, causing remounting to fail to initialize workers again.
