v2.19.0

What's New

• Word-level tracked redlines — Document comparison generates tracked changes at word granularity, matching Word's native behavior.
• Watermark dialog — Configure and apply watermarks through a responsive toolbar entry.
• Selected OOXML extraction — Export any text selection as structured OOXML with inherited styles and numbering scope.

Improvements

• Textbox typing is 330ms faster per keystroke through nested story projection reuse and table catalog scoping.
• Metadata preservation — Anchor identity, geometry, and citations now survive collaborative edits and comparison operations.
• Tracked changes stability — Paragraph splits, row exceptions, note markers, and footnotes survive across edits.
• Diff and compare correctness — DOCX metadata graphs, REF field topology, and tracked paragraph marks replay reliably.
• Search responsiveness — Active matches refresh immediately after edits and Replace All operations.
• Rendering fidelity — Section and page borders, PDF-bearing EMF images, inline markup text, and caret positioning all work correctly.

Fixes

• Stabilize SDK room creation under concurrent requests.
• Preserve comment identity during collaboration upgrade.
• Extract nested DrawingML textbox pictures once instead of repeatedly.
• Normalize default-only note parts in comparison.
• Stop false-positive header and footer change blocking in compare apply.
• Allow links beside pending revisions.
• Correct pointer offsets after wrapped text deletions.
• Update linked styles on list level changes.
