# UnifiedWriter v5.52 Remaining Compatibility Notes

The v5.52 build adds diagnostics and productization hardening, not a claim of complete Google Docs or Word parity. The following areas remain high-priority for later builds.

1. Selection/IME/Undo must continue to be tested on real Japanese/Chinese/Korean input.
2. Table grid behavior must continue toward full rowspan/colspan normalization and page splitting.
3. Image wrapping/floating placement must continue toward high-fidelity layout and DOCX DrawingML mapping.
4. Comments, suggestions, track changes and document comparison require dedicated review-model work.
5. Header/Footer/Footnote must evolve toward section-specific direct editing and high-fidelity DOCX import/export.
6. DOCX round-trip must preserve unknown parts and relationship graphs with increasing precision.
7. Print/PDF output must be visually compared against sample documents.
