Percona XtraDB Cluster 5.6.40-26.25 Is Now Available

Percona announces the release of Percona XtraDB Cluster 5.6.40-26.25 (PXC) on June 20, 2018. Binaries are available from the downloads section or our software repositories.

Percona XtraDB Cluster 5.6.40-26.25 is now the current release, based on the following:

• Percona Server for MySQL 5.6.40
• Galera/Codership WSREP API Release 5.6.39
• Galera Replication library 3.23

All Percona software is open-source and free.

New feature

• PXC-907: New variable wsrep_RSU_commit_timeout allows to configure RSU wait for active commit connection timeout (in microseconds).

Fixed Bugs

• PXC-2128: Duplicated auto-increment values were set for the concurrent sessions on cluster reconfiguration due to the erroneous readjustment.
• PXC-2059: Error message about the necessity of the SUPER privilege appearing in case of the CREATE TRIGGER statements fail due to enabled WSREP was made more clear.
• PXC-2091: Check for the maximum number of rows, that can be replicated as a part of a single transaction because of the Galera limit, was enforced even when replication was disabled with wsrep_on=OFF.
• PXC-2103: Interruption of the local running transaction in a COMMIT state by a replicated background transaction while waiting for the binlog backup protection caused the commit fail and, eventually, an assert in Galera.
• PXC-2130: Percona XtraDB Cluster failed to build with Python 3.
