What is Section 508, and what does it’s “refresh” mean?

The Section 508 “refresh” of the ADA was issued as a final rule by the Access Board and jointly updated and reorganized the Section 508 standards in response to market trends and innovations, such as the convergence of technologies. The refresh also harmonizes these requirements with other guidelines and standards both in the U.S. and abroad, including standards issued by the European Commission and with the Web Content Accessibility Guidelines (WCAG), a globally recognized consensus on the standard for web content accessibility, and information and communication technology.

Specifically, the rule references WCAG 2.0 Level AA success criteria and applies them not only to websites but also to electronic documents and software.
