Introduction

Welcome to KC News, your monthly briefing on what’s new and updated in the TPGi Knowledge Center.

Knowledge Base

ARC Rules and Knowledge Base Content

We’ve made quite a few updates and additions to the Knowledge Base since our last newsletter: rules, testing procedures, reference guides, and accessible web content development articles.

Highlights include:

  • Making changes to the Rules Engine and Knowledge Base: a new process you can use to suggest changes to how we interpret and address WCAG Success Criteria.
  • Correct Accessible Name: new rule, test procedure, and recommendations.
  • Table header cell is empty: previously skimpy guidance has been fleshed out.
  • Android and iOS: a range of new and updated guidance related to WCAG conformance.
  • 3rd Party Content: updated rule plus new guidance for some specific types of content.

Catch up with all the latest changes in Release 2025.10 (up to September 24) on the Knowledge Base Release page.
