Release notes

Added

• CLI: Add --fail-on flag to control exit code by severity

  • Configure minimum severity level that triggers non-zero exit code
  • Options: error (default), warning, info
  • --fail-on warning exits non-zero on warnings or errors
  • --fail-on info exits non-zero on any diagnostic
  • Useful for CI/CD pipelines with different strictness levels

• Severity: Add Info severity level for low-priority issues

  • New severity level below Warning for informational diagnostics
  • Allows rules to report suggestions without affecting exit codes by default
  • Can be promoted to affect exit codes via --fail-on info

• MD060 (table-column-count): Smart max-width inheritance from MD013

  • Automatically inherit max-width from MD013 line-length when not explicitly set
  • Reduces configuration duplication between MD013 and MD060
  • Explicit MD060 max-width still takes precedence

Fixed

• MD063 (heading-capitalization): Handle inline code at start of heading (fixes #228)

  • Headings starting with inline code (e.g., `code` text) now correctly apply sentence case to subsequent text
  • Previously, the word after inline code was incorrectly lowercased
  • Applies to all non-text segments (code, links, HTML) at heading start

• MD063 (heading-capitalization): Preserve acronyms and brand names in link text

  • Link text with internal capitals (e.g., [GitHub](url)) is now preserved
  • preserve_cased_words setting applies to link text, not just plain text
  • Prevents incorrect lowercasing of brand names within links

• MD063 (heading-capitalization): Handle inline HTML tags

  • Inline HTML tags like <kbd>, <abbr>, <code> are now recognized as separate segments
  • Prevents HTML tags from interfering with capitalization detection
  • Supports self-closing tags and tags with attributes

• MD063 (heading-capitalization): Preserve caret notation for control characters

  • Caret notation like ^A, ^C, ^Z (representing Ctrl+A, Ctrl+C, Ctrl+Z) is preserved
  • Prevents incorrect lowercasing of control character representations
  • Supports full range: ^@ through ^_ and ^A through ^Z
