Amazon Aurora MySQL-Compatible Edition 8.4.8 Support

Starting today, Amazon Aurora MySQL-Compatible Edition 8.4 will support MySQL 8.4.8, including several security enhancements, bug fixes, and new features.

New Features

  • Post-quantum TLS (PQ-TLS) Key Exchange: Provides post-quantum cryptography options for encrypting 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 for use-cases like merging shards, reporting, and backups.
  • Delayed Replication: Lets you set a configurable replication lag to protect against accidental data loss.

What to do

  • Upgrade your databases during scheduled maintenance windows using automatic minor version upgrades.
  • Enable automatic minor version upgrades and use the AWS Organizations Upgrade Rollout Policy to orchestrate upgrades across your clusters in phases.
  • Perform minor version upgrades in-place or via snapshot restore.

This release is supported in all AWS Regions where Aurora MySQL is available.
