Based on Percona Server 5.6.15-63.0 including all the bug fixes in it, Galera Replicator 3.3 and on Codership wsrep API 5.6.15-25.2 is now the current General Availability release. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.6.15-25.4 milestone at Launchpad.
Binlog events were created for the statements for non-InnoDB tables, but they were never cleaned from transaction cache, which could lead to node crash. Bug fixed #1277986.
clustercheck script would mark node as down on Debian based systems if it was run with default values because it was looking for the defaults-extra-file in the wrong directory. Bug fixed #1276076.
Deadlock would happen when NULL unique key was inserted. Workaround has been implemented to support NULL keys, by using the md5 sum of full row as key value. Bug fixed #1276424.
Builds now use system Zlib instead of bundled one. Bug fixed #1277928.
If transaction size exceeds the wsrep_max_ws_size limit, there will appear a warning message in the error log and replication is skipped. However, the transaction was committed in the master node, and cluster would be in inconsistent state. Bug fixed #1280557.
wsrep_load_data_splitting defaults to OFF now, using it turned ON with autocommit set to 0 is not recommended.
Other bugs fixed: #1279844.
We did our best to eliminate bugs and problems during the testing release, but this is a software, so bugs are expected. If you encounter them, please report them to our bug tracking system.
