Release notes

Fixed

• MD031/MD046: Detect code blocks inside lists (fixes #276)

  • MD031 with list-items=true now correctly flags fenced code blocks inside lists
  • MD046 with style=fenced now correctly flags indented code blocks inside lists
  • Uses pulldown-cmark for accurate CommonMark-compliant code block detection
  • Properly distinguishes between code blocks and footnote/admonition/tab content

• MD057: Check reference-style link definitions for broken links (fixes #274)

  • Reference-style link definitions like [ref]: ./path.md are now checked
  • Previously only inline links [text](./path.md) were validated
  • All existing validations apply: external URLs skipped, .html→.md fallback, URL decoding

• MD007: “Do What I Mean” behavior for indent configuration (fixes #273)

  • When indent is explicitly set without style, automatically use fixed style
  • Setting indent = 4 now actually uses 4-space increments as expected
  • Warning shown if both indent and style = "text-aligned" are set (contradictory)

• MD030: Prevent false positives in math blocks (fixes #275)

  • Math blocks ($$...$$) are now detected and excluded from list marker spacing checks
  • Fixes incorrect warnings about list spacing inside LaTeX display math
