Summary

Added documentation for 'IntegrationTarget' and 'ResponseTransferMode' properties in API Gateway method integration

Security assessment

The changes document new configuration options for API Gateway integrations (IntegrationTarget for VPC links and ResponseTransferMode for streaming/buffered responses). While ResponseTransferMode could influence data handling patterns, there is no explicit mention of security vulnerabilities or security feature enhancements in the diff.
