Release mcp-v0.15.2 · superdoc-dev/superdoc

Now I have enough information to write the release notes. Let me compile them based on the commits, changes, and voice guide:

Document Host — Headless structured document runtime for invoking operations and exporting .docx files without the visual editor.

Image rendering inside textbox — Images now display correctly within textbox shapes.
Toolbar with mixed fonts — Shows blank instead of falling back to Arial when multiple fonts are selected.
Font picker dropdown — Opens on input click instead of requiring double-click.
CJK wrapping after numeric runs — Line breaking now works correctly in long-word scenarios.
Heading style conflicts — Localized Word styles now resolve correctly to inherit from built-in style definitions.
Nested structured document tags — SDTs now render when nested inside other SDTs.
Tracked changes in editing mode — Direct typing stays plain text instead of being marked as a change.
Tracked rewrite corruption — Large single tracked mutations now use coarse whole-range rewrites to prevent artifact anchors in projected edits.

Table border fidelity — Compound borders (double, triple, thinThick variants) now render with measured band widths matching Word; interior gridlines paint continuously.
Border conflict resolution — Shared cell edges resolve by weight, style, and color per ECMA-376 spec.
Table styles — Base shading from table styles surfaces as the wholeTable conditional layer; conditional regions resolve correctly across gridSpan and vMerge.
Percent-width tables — Tables now honor authored grid proportions instead of content-sizing; total width and column splits match Word exactly.
Merged cell rendering — vMerge-only rows retain one-line height; interior row boundaries paint continuously without gaps.
Outset/inset borders — Render as separate-borders bevel (raised frames and sunken cells) instead of heavy black lines.
Document diffing — Enhanced change detection algorithms.

The following unstable Document API operations have been removed — use core insert/delete/replace operations instead:

blocks.split, blocks.merge, blocks.move
lists.getState, lists.apply, lists.continue, lists.restart, lists.remove
tables.moveRow
paragraphs.setMarkRunProps
