Percona Distribution for MySQL 8.0.46 using Percona XtraDB Cluster has been released on Wednesday, July 23, 2026.

Try it out using the Installation guide.

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.

Security updates

This release addresses the following security vulnerabilities:

  • CVE-2026-48165: A vulnerability in the handling of the wsrep_sst_donor and wsrep_sst_receive_address system variables allowed a high-privileged user to execute arbitrary shell commands with the privileges of the mariadbd process during State Snapshot Transfer (SST) due to improper input sanitization (CVSS 3.1 Base Score 7.2). :contentReference[oaicite:0]{index=0}.
