Release notes

Added

• MD072: Custom key order for frontmatter sorting (fixes #290)
  • New key-order config option to define preferred key ordering
  • Keys in the order list appear first, unlisted keys sort alphabetically after
  • Example: key-order = ["title", "date", "author"] puts title first

Fixed

• MD060: Preserve blockquote prefix when formatting tables

  • Tables inside blockquotes (e.g., > | A | B |) now correctly preserve the prefix
  • Supports nested blockquotes (>>, >>>) with proper prefix preservation
  • Works with all formatting styles (aligned, compact, tight)

• MD057: Skip link patterns inside LaTeX math spans (fixes #289)

  • Link-like patterns inside $...$ or $$...$$ are no longer flagged as broken links
  • Prevents false positives from LaTeX commands that resemble markdown links

• MD030: Skip empty marker lines without content (fixes #288)

  • Lines with only a list marker (no content) are now skipped
  • Prevents incorrect warnings about spacing on empty list items

• MD031/MD032/MD058/MD065: Auto-fix preserves nested blockquote prefix (fixes #268)

  • When inserting blank lines in blockquotes, the blockquote prefix is now preserved
  • Works correctly with nested blockquotes (>>, >>>)
  • Blank blockquote lines use > without trailing space (per markdownlint-cli)

• MD005/MD007: Prevent oscillation between rules

  • Ordered and unordered list items are now tracked in separate groups
  • Fixes cases where MD005 and MD007 would fight over indentation
