Use the source appropriate to the decision. Version/status matters: specifications define requirements or platform behavior, while APG and tutorials inform implementation and must be tested in the target environment.

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.
