On October 8, 2026, AWS extended GuardDuty RDS Protection beyond login anomalies to detect data exfiltration and destruction in Aurora PostgreSQL and RDS for PostgreSQL, using agentless behavioral baselines. Turn on the 30-day free trial if you run PostgreSQL — but know that MySQL remains outside the scope.

On 2 October 2026 AWS Health launched a version catalog that gives a centralised view of the software-version lifecycles across AWS services, starting with RDS, EKS and Lambda. Teams on Business Support Plus, Enterprise Support or Unified Operations can query it through an API to build upgrade plans before end of support, instead of absorbing lifecycle events one by one.

Aurora MySQL 8.4.8, available in early September 2026, adds delayed replication: a replica deliberately applies each change with a configurable lag, making it the only copy that does not reproduce an accidental DROP TABLE or DELETE. Configure it by stored procedure and write the recovery runbook before you need it.
