The Accessibility validation server on Rocket Validator has been upgraded to Axe Core 4.10.2, which fixes some false positives and adds a 10x performance improvement in pages with lots of similar elements.

<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>, 4.10.2, which fixes some false positives and adds a 10x performance improvement in pages with lots of similar elements. This release also prevents axe from sometimes crashing when a page changes in the middle of a test</p>

Because a few false positives were fixed, this release may see the number of reported issues go down.

As usual, you don't need to do anything on your side to update, we've upgraded our servers with this version so they'll run automatically in your next reports.
