The Accessibility validation server on Rocket Validator has been upgraded to Axe Core 4.7, improving many accessibility rules.

<p>We've upgraded our Accessibility validation servers to the latest version of <a rel="nofollow" href="https://github.com/dequelabs/axe-core">axe-core</a>, 4.7, which improves many accessibility rules and fixes some bugs from previous versions.</p>

Version 4.7 of Axe Core adds support for some features that have been added to browsers in the last year. No new rules were added, and it does not make axe-core stricter. The number of issues reported by this version may be lower than the ones reported in 4.6.

The `aria-roledescription` rule has been deprecated, and the impact of the `scrollable-region-focusable` has been increased to serious.
