[dependabot]

Bumps markdown-it from 14.2.0 to 15.0.1.

Changelog

Sourced from markdown-it's changelog.

[15.0.1] - 2026-08-27

Changed

• doc: replace oxide theme with custom one.

Fixed

• Fixed code span parsing after lookaheads for unclosed link and image labels, #1201.
• Preserve spaces in code spans whose content consists only of spaces, #1180.
• Preserve brackets around IPv6 address literals when normalizing links, #1204.

Security

• Fixed quadratic complexity when replacing fuzzy links.
• Fixed quadratic complexity in scheme backscan (inline linkify rule).

[15.0.0] - 2026-07-30

Added

• Exposed parser internals classes as static properties on markdownit.
• Bundled TypeScript declarations. Remove @types/markdown-it if you used it.
• Added the markdown-it/browser export with bundled ESM and UMD builds.
• Added colored CLI help on supported terminals via argparse 3.
• Added reference labels to link/image tokens, #938.
• Added reference_definition tokens. They remain stripped by default for backwards compatibility, #1055. Also adjusted the line-break heuristic to keep output exactly the same.

Changed

• [breaking] linkify-it => v6
  • No fuzzy links by default.
  • No auth part check by default.
  • Unicode punctuation terminates the link by default (should help with CJK).
  • See linkify-it changelog for other changes.
• Package root now resolves to prebuilt ESM and CJS files instead of raw sources. Distribution files were reorganized under dist/ and dist/browser/.
• Migrated to Typescript.
• entities => v8. Can be rolled back to v7 if compatibility issues happen.
• Moved validateLink, normalizeLink and normalizeLinkText from properties to prototype methods.
• Reworked issue templates and contribution guidelines.

Removed

• [breaking] Removed package-internal subpath exports (markdown-it/lib/* and similar). Use the static classes exposed on markdownit instead.
• [breaking] Removed obsolete StateBlock#ddIndent, #1139. Update markdown-it-deflist to keep it working.

Fixed
