v0.1.0-next.33

Released: 2026-06-07

Features

• Configurable hierarchical heading-ID strategy for HeadingLinks: headingIds: { strategy: 'hierarchical' } prefixes each heading slug with its ancestor chain's final id (foo / foo-moo / foo-moo-mew) and dedups on the full path, via a shared SlugAllocator so the rendered <hN id> and the headings export use one algorithm. The default stays flat (byte-stable with previous output). (#871, #872) (4e34adf, 8458404)

Bug Fixes

• Pipeline::set_heading_id_strategy is now public, so a custom pipeline that hand-wires HeadingLinksPlugin::with_strategy(Hierarchical) can keep the headings export in sync with the rendered ids. (#871) (729fba7)

Other Changes

• TS config types mirror the new headingIds field (HeadingIdsConfig on MarkdownFeaturesConfig), and the heading-links docs page covers the strategy knob, the hierarchical rules, and the anchor-breaking caveat. (#871) (3130501)

• Unit + integration tests covering the hierarchical heading-ID strategy: sibling pops, depth jumps, full-path dedup, parent prefixes, reset between documents, JSX-nested headings, and a flat golden regression guarding byte-stability. (#871) (a7243cc)
