AWS cognito documentation change
Summary
Added a changelog entry for March 23, 2026, documenting an update to clarify Lambda trigger retry behavior (retries may occur for timeouts without a fixed retry count).
Security assessment
This is a documentation update clarifying existing system behavior. It mentions retry logic for Lambda timeouts, which could have reliability implications but does not indicate a security vulnerability or add new security guidance.
