AWS sms-voice documentation change
Summary
Restructured two-way SMS documentation into bullet points, added information about MMS limitations, Connect Customer availability, and message ordering guarantees
Security assessment
The changes are informational updates about service capabilities and limitations. While the message ordering note highlights reliability considerations, there's no evidence of a security vulnerability being addressed. The content focuses on functional limitations rather than security controls.
