Percona is glad to announce the first General Availability release of Percona XtraDB Cluster 5.6 on January 30th 2014. Binaries are available from downloads area or from our software repositories.

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 first General Availability release. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.6.15-25.3 milestone at Launchpad.

New Features

New meta packages are now available in order to make the Percona XtraDB Cluster installation easier.

Debian/Ubuntu debug packages are now available for Galera and garbd.

xtrabackup-v2 SST now supports the GTID replication.

Bugs fixed

Node would get stuck and required restart if DDL was performed after FLUSH TABLES WITH READ LOCK. Bug fixed #1265656.

Galera provider pause has been fixed to avoid potential deadlock with replicating threads.

Default value for binlog_format is now ROW. This is done so that Percona XtraDB Cluster is not started with wrong defaults leading to non-deterministic outcomes like crash. Bug fixed #1243228.

During the installation of percona-xtradb-cluster-garbd-3.x package, Debian tries to start it, but as the configuration is not set, it would fail to start and leave the installation in iF state. Bug fixed #1262171.

Runtime checks have been added for dynamic variables which are Galera incompatible. Bug fixed #1262188.

During the upgrade process, parallel applying could hit an unresolvable conflict when events were replicated from Percona XtraDB Cluster 5.5 to Percona XtraDB Cluster 5.6. Bug fixed #1267494.

xtrabackup-v2 is now used as default SST method in wsrep_sst_method. Bug fixed #1268837.

FLUSH TABLES WITH READ LOCK behavior on the same connection was changed to conform to MySQL behavior. Bug fixed #1269085.

Read-only detection has been added in clustercheck, which can be helpful during major upgrades (this is used by xinetd for HAProxy etc.) Bug fixed #1269469.

Binary log directory is now being cleanup as part of the XtraBackup SST. Bug fixed #1273368.

First connection would hang after changing the wsrep_cluster_address variable. Bug fixed #1022250.

When gmcast.listen_addr was set manually it did not allow nodes own address in gcomm address list. Bug fixed #1099478.

GCache file allocation could fail if file size was a multiple of page size. Bug fixed #1259952.

Group remerge after partitioning event has been fixed. Bug fixed #1232747.

Fixed the OpenSSL linking exceptions. Bug fixed #1259063.

Fixed multiple build bugs: #1262716, #1269063, #1269351, #1272723, #1272732, and #1261996.

Other bugs fixed: #1273101, #1272961, #1271264, and #1253055.
