Aurora PostgreSQL Gets Fresh Security Patches Across Five Versions
Amazon Aurora PostgreSQL-Compatible Edition now supports five new minor versions (18.4, 17.10, 16.14, 15.18, and 14.23) packed with bug fixes and CVE patches from the PostgreSQL community. You can roll these updates out automatically during maintenance windows, and if you're managing multiple databases, AWS Organizations Upgrade Rollout Policy lets you stage deployments across environments—perfect for testing on non-critical systems first.
