## WCAG 2.2 Changes To Apply

WCAG 2.2 adds nine success criteria:

- 2.4.11 Focus Not Obscured (Minimum), AA
- 2.4.12 Focus Not Obscured (Enhanced), AAA
- 2.4.13 Focus Appearance, AAA
- 2.5.7 Dragging Movements, AA
- 2.5.8 Target Size (Minimum), AA
- 3.2.6 Consistent Help, A
- 3.3.7 Redundant Entry, A
- 3.3.8 Accessible Authentication (Minimum), AA
- 3.3.9 Accessible Authentication (Enhanced), AAA

It removes obsolete 4.1.1 Parsing.

Read the criterion before applying it: do not rely on abbreviated lists for exceptions, applicability, or a conformance claim.
