rupor-github/fb2cng v1.3.1

on GitHub

New features:

• Added legacy OPF2 cover metadata to EPUB3 output for Apple Books compatibility.
  • EPUB3 now emits both:
    • meta name="cover" content="book-cover-image"
    • properties="cover-image" on the actual cover image manifest item.
  • The legacy cover meta points directly to the raster cover image, while cover.xhtml continues to use the SVG wrapper.
  • Added EPUB3 OPF test coverage for the Apple-compatible cover metadata.
• Added configurable device TOC nesting via document.toc_type.
  • Supported TOC types:
    • normal — preserve full section nesting.
    • old_kindle — restrict nesting for old Kindle/kindlegen compatibility.
    • flat — make navigation entries top-level siblings.
  • Kept generated visible TOC pages unchanged for EPUB2, EPUB3, and KFX.
  • Removed presentation classes from EPUB3 nav.xhtml.
  • Added shared TOC shaping helper and tests.
  • Added regression tests for normal, old_kindle, and flat nesting in EPUB2, EPUB3, and KFX.
