Does WCAG 2.1 checklist Replace WCAG 2.0?

WCAG 2.0 was released nearly 10 years ago with 12 guidelines for digital accessibility, divided among four principles Perceivable, Operable, Understandable and Robust. Each guideline of the WCAG checklist has a list of success criteria. After 4 years of work, the Accessibility Guidelines Working Group (AGWG) of the W3C released its latest recommendations. Still, WCAG 2.1 doesn’t replace or canceled. WCAG 2.1 only adds few new success criteria to the existing WCAG checklist 2.0. Authorities that enforce major accessibility laws, including the Americans with Disabilities Act (ADA), Section 508 of the Rehabilitation Act, and the Accessibility for Ontarians with Disabilities Act (AODA), continue to require complying with WCAG 2.0 level AA. But W3C encourages organizations to use the most recent version of WCAG when developing or updating their content or digital accessibility policy.
