Amazon Aurora now supports PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23

Amazon Aurora PostgreSQL-Compatible Edition now supports PostgreSQL versions 18.4, 17.10, 16.14, 15.18, and 14.23 which include bug fixes from the PostgreSQL community and Aurora-specific enhancements. We recommend upgrading to the latest minor versions to address known Common Vulnerabilities and Exposures (CVEs) and benefit from these improvements, as detailed in the [release notes](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraPostgreSQLReleaseNotes/AuroraPostgreSQL.Updates.html). You can upgrade your databases during scheduled maintenance windows using automatic minor version upgrades. To simplify operations at scale, enable automatic minor version upgrades and use the AWS Organizations [Upgrade Rollout Policy](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.Maintenance.AMVU.UpgradeRollout.html) to orchestrate multiple upgrades in phases, validating on lower-priority environments before upgrading your most critical ones. For more information, see [Upgrading Amazon Aurora PostgreSQL DB clusters](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER%5FUpgradeDBInstance.PostgreSQL.html). Amazon Aurora is designed for high performance and availability at global scale with full PostgreSQL compatibility. It provides scale-to-zero serverless compute, Aurora Global Database for multi-Region resilience, Aurora I/O-Optimized for improved price performance on I/O-intensive workloads, and built-in security and continuous backups.
