Link to WCAG 2.1 instead of 2.0?

^{Originally posted by robinmetral August 10, 2022} Can we link to the WCAG 2.1 website instead of WCAG 2.0? I'm not sure if this is consistent throughout the site, but I'm seeing it on e.g. the checklist links to success criteria. For instance, users are sent to 3.1.5 Reading Level (WCAG 2.0) instead of 3.1.5 Reading Level (WCAG 2.1).

Am I missing a reason why these should continue to link to 2.0?
