v0.10.0

What's new

Multi-format build (--format pdf,epub)

• build now accepts --format (pdf, epub, or pdf,epub) to produce one or both outputs in a single run
• Chrome only required when PDF is in the format list — EPUB-only builds skip Chrome entirely
• Output paths are inferred from --out extension when a single format is used, or derived as a base name for multi-format

EPUB theming (same theme system, reflowable output)

• Themes now produce EPUB-ready CSS via a new reflowable base stylesheet (relative units, no @page/print-only rules)
• Every built-in and custom theme works for EPUB without modification
• The epub command now accepts --theme, --css, --color-*, --font-*, --density, --allow-network-fonts
• EPUB CSS uses the same --pdf-* custom property contract as PDF output

Cover image expansion

• SVG cover images: dimensions extracted from width/height attributes or viewBox (supports px, in, cm, mm, pt, pc)
• WebP cover images: decoded via golang.org/x/image/webp
• EPUB also accepts SVG covers

Custom paper sizes

• Parse custom dimensions like 6x9in, 152.4mm x 228.6mm, 6x9 (inches default)
• Enables trade-paperback and non-standard trim sizes without manual CSS overrides
