*** Important Note ***
The IBM Accessibility Checklist for Web and Web-Based Documentation - Version 6.1 updates the Web Checklist v.5.2. This new version of the web checklist alters the numbering for all checkpoints, bringing them into alignment with WCAG. Each of the checkpoints has a new unified format, allowing the same rationale and general techniques to apply to both web and software technologies. It is required for all deliverables with a Plan Checkpoint Date on or after August 25, 2016.
If your deliverable has a Plan Checkpoint Date on or before August 24, 2016 you can continue to use the Web Checklist v5.2.
