Percona Distribution for MySQL 8.0.46 using Percona XtraDB Cluster (2026-07-23)

Percona Distribution for MySQL is more than just a version of MySQL; it is a comprehensive solution that combines Percona Server for MySQL with additional tools to create a cohesive environment. This distribution is reliable, scalable, and secure, ensuring that all components have been tested to work seamlessly together. You can choose from two download options: one that uses Percona Server for MySQL and another that utilizes Percona XtraDB Cluster. Refer to Install Percona Distribution for MySQL.

This release is focused on the Percona XtraDB Cluster-based deployment variation. It is based on Percona XtraDB Cluster 8.0.46-38.

Final 8.0 series release

MySQL 8.0 has officially reached End of Life (EOL). Percona Distribution for MySQL 8.0.46 and Percona XtraDB Cluster 8.0.46-38 are the final standard releases in the 8.0 series.

Future support depends on your product:

Percona Distribution for MySQL 8.0: Fully retired. No further releases, bug fixes, security updates, or post-EOL support will be provided.

Percona XtraDB Cluster 8.0: Standard public support has ended, but extended lifecycle options are available: * Paid subscribers: Access to critical updates and precompiled binaries through a private repository. * Community users: Access to source code only, published quarterly with a delay.

Recommendation: Upgrade to MySQL 8.4 to ensure continued standard support and platform stability.
