I didn’t try my very hardest to find a list of all of the new Success Criteria in Web Content Accessibility Guidelines 2.1 (WCAG 2.1) that were not a part of WCAG 2.0, but if there is such a list, it’s not easy to find.

And given the formatting for WCAG 2.0, it’s not all that easy to make such a list, either. But in case this is helpful to anyone, here are the seventeen new Success Criteria in WCAG 2.1, which became a W3C Recommendation in June 2018, with links to each criterion in the specification:

1: Perceivable

• 1.3: Adaptable

  • 1.3.4: Orientation
  • 1.3.5: Identify Input Purpose
  • 1.3.6: Identify Purpose

• 1.4: Distinguishable

  • 1.4.10: Reflow
  • 1.4.11: Non-text Contrast
  • 1.4.12: Text Spacing
  • 1.4.13: Content on Hover or Focus

2: Operable

• 2.1: Keyboard Accessible

  • 2.1.4: Character Key Shortcuts

• 2.2: Enough Time

  • 2.2.6: Timeouts

• 2.3: Seizures and Physical Reactions

  • 2.3.3: Animation from Interactions

• 2.5: Input Modalities

  • 2.5.1: Pointer Gestures
  • 2.5.2: Pointer Cancellation
  • 2.5.3: Label in Name
  • 2.5.4: Motion Actuation
  • 2.5.5: Target Size
  • 2.5.6: Concurrent Input Mechanisms

4: Robust

• 4.1: Compatible

  • 4.1.3: Status Messages

Note that Section 2.5: Input Modalities is the only entirely new section, and that there were no additional Success Criteria added under Section 3:Understandable.
