AWS AmazonElastiCache documentation change
Summary
Added documentation for Valkey 8.1 release including new features like memory-optimized hash tables, Bloom filters, COMMANDLOG monitoring, and performance improvements
Security assessment
The changes document new features and performance enhancements rather than addressing security vulnerabilities. While COMMANDLOG adds monitoring capability for slow executions/large requests, there's no explicit mention of security vulnerabilities being patched or security-specific functionality being added.
