Release Notes

Improved Audit Rules

Accessibility Enhancements

  • aria-required-parent: Now checks both explicit ARIA roles and implicit HTML element roles (e.g., <li> outside <ul>)
  • color-contrast: Extended detection to include CSS class patterns (Tailwind, Bootstrap), <style> block analysis, and framework-agnostic low-contrast patterns
  • link-text: Improved accessible name computation following ARIA spec, better detection of icon-only links and SVG accessibility
  • skip-link: Now recognizes multiple WCAG 2.4.1 bypass mechanisms including <main> landmarks and heading navigation
  • zoom-disabled: Aligned with Lighthouse threshold (maximum-scale < 5), added minimum-scale detection

Performance Improvements

  • source-maps: Now detects SourceMap HTTP headers, resolves relative URLs, and checks fetched script content for sourceMappingURL references
  • js-libraries: Enhanced detection with inline code pattern matching, HTML runtime markers, and CVE references for vulnerabilities
  • total-byte-weight: Aggregates resources across all crawled pages with deduplication, provides detailed breakdowns by resource type
  • unminified-css/unminified-js: Improved analysis with potential savings estimates, better minification heuristics
  • doctype: Handles BOM characters and XML declarations, validates doctype position

Crawl & Core

  • redirect-chain: Now specifically flags entry URL redirects and provides chain visualization
  • viewport: Handles both single and double quote attribute syntax
