v2.0.9

IMPORTANT

Percona XtraDB Cluster v8.0 has reached EOL as of April 30th 2026, so all users are advised to migrate to Percona XtraDB Cluster v8.4.

As of pxc-release v1.1.0 and later, Percona XtraDB Cluster v8.4 is supported.

As of pxc-release v2.0 and later suppot for MySQL 5.7 has been removed from the bosh release and "5.7" is no longer a valid version to deploy

To use Percona XtraDB Cluster v8.4, set the pxc-mysql job's mysql_version property to "8.4".

The default MySQL version remains "8.0" for compatibility with existing consumers, but the default will change in a future major version bump.

As with any major database version upgrade, testing and ensuring backups prior to upgrading in production is strongly encouraged.

Release Notes

Bugs Fixed

• Resolved data integrity issue (MySQL Bug #116741) during temporary table rollovers by updating to a custom Percona XtraDB Cluster v8.4 build. This fixes a bug where workloads heavily utilizing temporary tables could return incorrect query results if the tables exceeded temptable_max_ram and were forced to convert from in-memory to disk-based InnoDB tables.

Dependency bumps

• Bumped Go to v1.26.7
• Updated module dependencies for pxc-release utilities
