Starting today, Amazon Aurora MySQL-Compatible Edition 8.4 will support MySQL 8.4.8. In addition to several security enhancements and bug fixes, Aurora MySQL 8.4.8 includes several improvements, such as support for post-quantum TLS (PQ-TLS) key exchange, transaction timeout, multi-source replication, and delayed replication. PQ-TLS provides you with post-quantum cryptography options for encrypting your data in-transit. Transaction timeout helps prevent performance issues caused by long-running transactions blocking innoDB purge.

Multi-source replication allows consolidation of data from multiple sources into a single replica to enable critical use-cases, such as merging shards, reporting, and backups. Delayed replication lets you set a configurable replication lag to protect against accidental data loss. To learn more about these replication features, please refer to the [launch announcement](https://aws.amazon.com/about-aws/whats-new/2026/09/amazon-aurora-mysql-multisourcerep-delayedrep/). For more details, refer to the [Aurora MySQL 8.4](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraMySQLReleaseNotes/AuroraMySQL.Updates.84Updates.html) and [MySQL 8.4.8](https://dev.mysql.com/doc/relnotes/mysql/8.4/en/news-8-4-8.html) release notes.

You can upgrade your databases during scheduled maintenance windows using automatic minor version upgrades. To simplify operations at scale, enable [automatic minor version upgrades](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Updates.AMVU.html) and use the AWS Organizations [Upgrade Rollout Policy](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.Maintenance.AMVU.UpgradeRollout.html) to orchestrate upgrades across your clusters in phases. You can perform minor version upgrades in-place or via snapshot restore. This release is supported in all [AWS Regions](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Concepts.RegionsAndAvailabilityZones.html#Aurora.Overview.Availability.MySQL) where Aurora MySQL is available.

[Amazon Aurora](https://aws.amazon.com/rds/aurora/) is designed for high performance and availability at global scale with full MySQL 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. To get started, take a look at Aurora’s [getting started page](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/CHAP_AuroraOverview.html).
