Amazon Aurora MySQL 8.4.10 Is Now Generally Available
AWS, Monday, November 2nd, 2026
Amazon Aurora MySQL 8.4.10 is generally available, adding GTID tags and support for up to 50,000 connections per instance.
AWS announced that Amazon Aurora MySQL-Compatible Edition 8.4 now supports MySQL 8.4.10, available in all regions where Aurora MySQL runs, and recommends upgrading for CVE fixes, bug fixes and performance improvements.
The release adds global transaction identifier tags, which let users assign tags to GTIDs to group related transactions in binary log replication.
It also supports up to 50,000 simultaneous connections per DB instance, so connection-heavy applications can scale without a pooling layer.
Upgrades can run automatically during maintenance windows and be orchestrated across clusters in phases with the AWS Organizations Upgrade Rollout Policy.
