Web Content Accessibility Guidelines
Web Content Accessibility Guidelines (WCAG)
The WCAG 2.2 was published in October 2023 and was designed to be backwards compatible, meaning that websites that conform to WCAG 2.2 will also conform to WCAG 2.0/2.1 (and therefore to policies that reference WCAG 2.0/2.1). The W3C advises the use of WCAG 2.2 to maximize future applicability of accessibility efforts. The W3C also encourages use of the most current version of WCAG when developing or updating Web accessibility policies.

On the horizon:
The WCAG 3.0 applies to all web content, apps, tools, publishing, and emerging technologies on the web. It is currently a working draft that is intended to develop into an official W3C Standard in a few years. While WCAG 3.0 is a successor of WCAG 2.2, it has a different scoring mechanism. It should be viewed and treated as an alternative set of guidelines, rather than an expansion of the WCAG 2.0 series.
