AWS AmazonRDS medium security documentation change
Summary
Added Aurora PostgreSQL Limitless Database version 16.8-limitless with new features, performance enhancements, and bug fixes including fixes for DROP DATABASE hangs, commit log race conditions, and analysis crashes
Security assessment
Bug fixes address critical stability issues: (1) Fixed a race condition in commit log processing causing '_commit time is invalid_' errors (potential data integrity risk), (2) Fixed backend unresponsiveness to system signals (availability impact), and (3) Crashes during automatic table analysis. These improve reliability but are not explicitly tied to security vulnerabilities. The 'strengthened deadlock detection' enhancement improves fault tolerance but lacks direct security context.
