This release adds the new RGAA standard to many rules. Of particular note is that some best practice rules under WCAG are required under the RGAA standard: focus-order-semantics (experimental), region, skip-link, table-duplicate-name. This means that these rules are tagged as both best-practice and RGAAv4. Applications which are filtering rules based on the best-practice tag will need to update the logic in order to handle RGAA rules that are tagged best-practice.
