    Release highlights¶

    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 5.7.40-43 (2022-11-28).

    The improvements and bug fixes for MySQL 5.7.40, provided by Oracle, and included in Percona Server for MySQL are the following:

    • ISO 8601 timestamps in log messages did not consider daylight saving time when --log-timestamps=SYSTEM was used.

    • The GRANT OPTION privilege was treated as related to database operations.

    • In specific cases, a TRUNCATE TABLE operation failed to release an acquired mutex.

    • A descending b-tree scan raised a debug assertion failure in debug builds.

    Find the full list of bug fixes and changes in the MySQL 5.7.40 Release Notes.

    Bug fixes¶

    • PXC-3821 : A fix to prevent the replication of a Performance Schema table truncation across the cluster.

    • PXC-512 : Replication slave from Percona XtraDB Cluster can exit if wsrep_forced_binlog_format=ROW.

    • PXC-4077 : Skipping transactions with an empty GTID event introduced GTID inconsistencies between PXC nodes.

    • PXC-4087 : A replicated transaction that aborted a local transaction while that transaction executed a rollback caused a server exit.
