AWS AmazonRDS medium security documentation change

Service: AmazonRDS · 2025-03-30 · Security-related medium

File: AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.Maintenance.md

Summary

Removed SQL Server-specific OS update methods and notes, added SQL Server to OS update coverage list, removed event-specific guidance

Security assessment

The change adds SQL Server to the list of engines receiving security-related OS updates ('improve customers' overall security posture'). The removed content appears to deprecate older update methods without security context. The security documentation addition is explicit in the modified paragraph.
