Version 12.0.1 Changelog (2026-07-20)

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

• Fixed rendering issue in specific scenarios after replacing selected text.

• Fixed an issue where undoing or redoing a cell value that was referenced in a formula would not update dependent charts correctly.

The WebViewer UI changelog covers user interface, customization, and workflow enhancements available through the Web SDK.

• Fixed several issues where multiple WebComponent instances on the same page could interfere with each other, including cross-instance React reconciliation crashes on dispose/re-render, UI.dispose() corrupting other instances or clearing more of the UI than intended, UI.setTheme() toggling the wrong instance's theme, and the Open file picker loading a document into the wrong instance.
• Fixed a crash that occurred when clicking an annotation in the Notes panel of one WebViewer instance while another instance was also mounted on the same page.
