AWS ai documentation change
Summary
Added detailed sample conversation flow for hotel cancellation use case, updated supported language listings, added hyperlinks to external datasets/resources, improved documentation structure, and enhanced security guidance around verification/consent
Security assessment
The added sample conversation demonstrates security-conscious practices like identity verification and explicit consent requirements for cancellations. While this shows security feature implementation, there's no evidence it addresses a specific vulnerability. The change documents existing security controls rather than patching issues.
