WCAG 2.2
WCAG 2.2 was finalized in 2023, though most digital accessibility legislation worldwide still references WCAG 2.0 or WCAG 2.1. The UK was the first region to have a WCAG 2.2 AA deadline (which was in October 2024) WCAG 2.1 is made up of all of the existing WCAG 2.1, plus 9 additional success criteria (2 more Level A, 4 more Level AA, and 3 more Level AAA) while deprecating Level A success criterion 4.1.1.
