Acquia Optimize has performed a round of periodic updates to our accessibility checks to improve the overall quality of accessibility scans.
An orange line with the label "Accessibility checks update" on your charts and tables in the Accessibility module indicates when your domain started scanning with the updated versions of checks.
All checks are updated automatically and Acquia Optimize users do not need to do anything in order to take advantage of the changes. However, as a consequence of the update, be aware that your accessibility compliance score may change.
