Percona is glad to announce the release of Percona XtraDB Cluster 5.6.38-26.23 on January 24, 2018. Binaries are available from the downloads section or from our software repositories.
Percona XtraDB Cluster 5.6.38-26.23 is now the current release, based on the following:

- Galera/Codership WSREP API Release 5.6.38
- Galera Replication library 3.21
All Percona software is open-source and free.
Fixed Bugs¶
- PXC-889: Fixed an issue where a node with an invalid value for
wsrep_provider
was allowed to start up and operate in standalone mode, which could lead to data inconsistency. The node will now abort in this case. Bug fixed #1728774 - PXC-850: ensured that a node, because of data inconsistency, isolates itself before leaving the cluster, thus allowing pending nodes to re-evaluate the quorum. Bug fixed #1704404
- PXC-875: Fixed an issue where toggling
wsrep_provider
off and on failed to reset some internal variables and resulted in PXC logging an “Unsupported protocol downgrade” warning. Bug fixed #1379204 - PXC-883: Fixed
ROLLBACK TO SAVEPOINT
incorrect operation on slaves by avoiding useless wsrep plugin register for a savepoint rollback. Bug fixed #1700593 - PXC-887: gcache .page files were unnecessarily created due to an error in projecting gcache free size when configured to recover on restart.
- PXC-895: fixed transaction loss after recovery by avoiding interruption of the binlog recovery based on wsrep saved position. Bug fixed #1734113
- PXC-897: fixed empty
gtid_executed
variable after recovering the position of a node with--wsrep_recover
. - PXC-906: fixed certification failure in the case of a node
restarting at the same time when frequent
TRUNCATE TABLE
commands and DML writes occur simultaneously on other nodes. Bug fixed #1737731 - PXC-914: Suppressing DDL/TOI replication in case of
sql_log_bin
zero value didn’t work when DDL statement was modifying an existing table, resulting in an error.
