Percona XtraDB Cluster is based on Percona Server for MySQL. Find a complete list of improvements and bug fixes in the Percona Server for MySQL 5.7.39-42 (2022-08-15).
The improvements and bug fixes for MySQL 5.7.39, provided by Oracle, and included in Percona Server for MySQL are the following:
- Enable the
performance_schema_show_processlistsystem variable to use an alternative implementation of the
SHOW PROCESSLISTstatement. Instead of querying the thread manager and holding a global mutex, which may affect performance, this implementation queries the active thread data from the Performance Schema and does not require a mutex.
A fresh installation of MySQL 5.7.39 or higher automatically creates the
processlist table. This table is not automatically created during an upgrade. For an upgrade, you must create the table manually.
- The system variable,
myisam_repair_threads, and the myisamchk
--parallel-recoveroption are removed.

Percona has added no improvements or bug fixes for this release.
