Percona XtraDB Cluster 5.6.32-25.17 is now available

Percona announces the new release of Percona XtraDB Cluster 5.6.32-25.17 on October 4, 2016. Binaries are available from the downloads area or our software repositories.

Percona XtraDB Cluster 5.6.32-25.17 is now the current release, based on the following:

• Percona Server 5.6.32-78.1
• Galera Replication library 3.17
• Codership wsrep API version 25

Bugs Fixed:

• Fixed DONOR node getting stuck in Joined state after successful SST. Bugs fixed #1608680 and #1611728.
• Removed protection against repeated calls of wsrep->pause() on the same node to allow parallel RSU operation.
• Fixed error when running SHOW STATUS during group state update.
• Setting the wsrep_auto_increment_control to OFF didn’t restore the original user set value.
• Corrected the return code of sst_flush_tables() function to return a non-negative error code and thus pass assertion.
• Using Percona XtraBackup as the SST method now requires Percona XtraBackup 2.3.5 or later.
• Fixed memory leak and stale pointer due to stats not freeing when toggling the wsrep_provider variable.
• Fixed failure of ROLLBACK to register wsrep_handler.
• Improved rollback process to ensure that when a transaction is rolled back, any statements open by the transaction are also rolled back.
• Fixed failure of symmetric encryption during SST.
• Performing an SST would display the encryption key in the logs. It’s recommended to use encrypt-key-file instead of encrypt-key option.
• Node transitioning to non-primary state with active ALTER TABLE could result in a crash.
• Fixed setting of seqno in grastate.dat to -1 on clean shutdown.
• Fixed failure of asynchronous TOI actions (like DROP) for non-primary nodes.
• Removed the unused sst_special_dirs variable.
• Added support of defaults-group-suffix for SST scripts.
• Other low-level fixes and improvements for better stability.
