AWS aurora-dsql documentation change
Summary
Removed preview service disclaimer and updated concurrency control mechanism description from 'modern concurrency control mechanisms' to 'modern, lock-free concurrency control mechanism'
Security assessment
The changes remove a preview status notice and refine technical implementation details of concurrency control. While lock-free mechanisms can impact performance and contention, there is no evidence this addresses a specific security vulnerability or weakness. The ACID compliance and data consistency claims remain unchanged.
