We've upgraded our Accessibility validation servers to the latest version of axe-core, 4.4, which fixes some bugs and introduces an upgraded version of the contrast checker, so you may want to re-check your sites to get the most up-to-date results.
## Enhanced contrast check The new [color contrast enhanced rule](https://dequeuniversity.com/rules/axe/4.4/color-contrast-enhanced) in Axe Core 4.4 checks that text elements have sufficient contrast between text in the foreground and background colors behind it in accordance with WCAG 2 AAA contrast ratio thresholds. Success criterion: Ensure color contrast of at least 7:1 for small text or 4.5:1 for large text, even if text is part of an image. Large text has been defined in the requirements as 18pt (24 CSS pixels) or 14pt bold (19 CSS pixels). ## Bug Fixes Check out the [4.4 release notes](https://github.com/dequelabs/axe-core/releases/tag/v4.4.0). ## Current accessibility ruleset Check out the full list of accessibility rules that are being checked currently by our web crawler Accessibility rules checked by Rocket Validator.
