v0.35.1

What's New in v0.35.1

Highlights

• XLSX wide-table layout fixes - improved handling for programmatically generated spreadsheets that emit column widths without customWidth, infer readable widths when column metadata is absent, repeat first-row print titles correctly, and add Excel-like cell text insets so adjacent text columns do not visually collide.
• PPTX text fidelity improvements - enhanced whitespace/tab preservation and East Asian typeface handling for PowerPoint conversion.
• Benchmark tooling updates - improved shared benchmark manifest/report plumbing, filtered issue comparisons, and richer PDF comparison behavior.
• Rust converter progress - expanded DOCX/XLSX/PDF conversion support in minipdf-rs, including dependency lockfile updates.
• Documentation refresh - synchronized README download links and translated README content.

Full Changelog: v0.29.0...v0.30.0

v0.29.0

What's New in v0.29.0

DOCX rendering fidelity release: substantial improvements to OOXML indent cascade, list label placement, CJK metrics, paragraph spacing, theme font resolution, and shape rendering. Improves Chinese/Japanese/Korean document fidelity and resolves several long-standing layout regressions.

Highlights

• OOXML indent cascade -- correct inheritance from styles per OOXML 17.3.1.12 and 17.9.3, with auto-tab handling for inherited list paragraphs.
• List label placement -- gate auto-tab snap on w:suff; correct CJK numbered-list label placement; prefer w:left twips over w:leftChars when both are present.
• CJK grid metrics -- recognize Chinese font aliases; include paragraph-mark font size in cell line height; skip empty/tab-only runs from line-height max.
• Paragraph spacing -- apply explicit pStyle SpacingBefore at top of page (narrowed to first paragraph); apply explicit SpacingBefore for first cell paragraph.
• Theme & font resolution -- resolve theme Latin font for runs without explicit rFonts; substitute Avenir LT Pro to Times New Roman for serif embedding.
• Shapes & anchors -- render explicit-fill shapes when stroke is also present; handle ObjectAnchor host paragraph (anchor image + shape).
• Chinese chromatography report fidelity -- targeted improvements driven by real-world test corpus.

Full Changelog: v0.28.0...v0.29.0

v0.28.0

What's New in v0.28.0

Highlights

• DOCX line-metrics & font fidelity -- font-aware top-of-page ascent, gated line-height growth on font-size jumps, Franklin Gothic line-height factor tuned to LibreOffice (1.149 -> 1.136), Times Roman widths for serif runs in Calibri-default docs, and TNR/Arial Bold wrap accuracy improvements.
• DOCX justification & wrapping -- preserve leading tab indent, run-boundary justify gaps, snap auto-numbered list label to next default tab stop, num-aligned tab override when list label overflows hanging indent, and explicit spacingAfter flag for paragraph spacing.
• DOCX CJK rendering -- digit-CJK gap insertion at run boundaries in the multi-format renderer, kinsoku no-end rule for opening punctuation, PDF-level CJK punctuation compression, and tolerance for Calibri Latin width overshoot in CJK runs (SA8000).
• DOCX layout fixes -- floating images anchored to paragraph line-box top (not baseline), skip line-height advance for wrapNone anchor-image-only paragraphs, skip SpacingBefore for first paragraph in table cell, outlined Wingdings bullets, KaiTi_GB2312 / FangSong_GB2312 font alias mapping.
• PDF engine -- cap justified line width when natural exceeds MaxWidth; split emoji range so Dingbats bullets use the text font.
• API -- ConvertToPdf(Stream) now auto-detects DOCX vs XLSX (#70).

Full Changelog: v0.27.0...v0.28.0

v0.27.0

What's New in v0.27.0

Highlights

This release focuses on DOCX-to-PDF rendering fidelity, with broad layout, text-wrap, and font-metric improvements plus PDF writer enhancements for image transparency and connector lines.

DOCX Conversion

• Conditional table borders -- honor band1Horz / firstCol conditional borders so styled tables match Word output.
• CJK baseline accuracy -- correct snap-to-grid baseline placement for KaiTi-family fonts.
• Justified line wrapping -- justified lines now stay within the right margin even when the wrap-width estimate undercounts; trailing underlined whitespace in justified paragraphs is suppressed.
• Wide sans-serif width estimation -- WordWrap uses a wider Helvetica reduction for wide sans-serif fonts.
• trHeight atLeast rows -- allow rows to shrink so they stay on the current page instead of forcing a page break.
• Floating-anchor host paragraphs -- skip lineHeight for wrapNone floating-anchor host paragraphs to avoid extra vertical space.
• Font weight detection + Montserrat metrics -- improved bold/weight detection and Montserrat character-width tables.
• Calibri-like font width estimation -- improved width estimation for Calibri-family fonts.
• Bold list text -- bold formatting is preserved on numbered/bulleted list runs.
• CJK + empty paragraph handling -- improved CJK font selection and empty-paragraph height handling.
• Header/footer images and connector lines -- added rendering support for connector lines and header/footer images.

PDF Writer

• Image alpha transparency -- support alpha transparency for images embedded during DOCX-to-PDF conversion.

Tooling / Repo

• New create-release skill for automating GitHub releases with CLI and GUI AOT binaries.
• New libreoffice-reference skill for looking up Office-to-PDF processing logic from local references.
