rupor-github/fb2cng v2.0.1

on GitHub

New features

• Native AZW3 conversion with --to azw3, without requiring KindleGen.
  • Device navigation, covers, thumbnails, images, SVG artwork, and embedded fonts.
  • Selectable compression: none, standard (default), or huffdic.
  • Optional APNX sidecars through document.azw3.apnx.

Backlinks and Templates

• Successful empty or whitespace-only backlink-template output now suppresses generated return links in EPUB/KEPUB, AZW3, KFX/AZW8, PDF, and Markdown.
• Backlink-template parsing or execution errors now fail conversion instead of silently inserting a fallback.
• Bundled backlink defaults remain unchanged.

Breaking Configuration Changes

• Replace --kfx-compression with --compression:
  • AZW3: none, standard, huffdic.
  • KFX/AZW8: none, lzma.
• Move Markdown image settings from document.images.markdown to document.markdown.images. The old key is no longer accepted.

Other Improvements

• Unified native CSS media-query evaluation and expanded debug diagnostics.
• Separated AZW3 and Kobo rendering adapters while preserving existing output behavior.
• Reorganized documentation, clarified configuration and reader limitations, and expanded regression coverage.
• Updated to Go 1.27.4 and refreshed dependencies.

Reader Notes

• Kindle footnote popups remain device- and firmware-dependent.
• For AZW3 embedded fonts require selecting Publisher Font on Kindle.
• APNX page numbers are approximate, not print-edition pagination.
