Percona XtraDB Cluster 5.6 GA 发布了，该版本基于 Percona Server 5.6, Galera 3, wsrep API 25, 和 Percona XtraBackup 2.1. 详细改进记录包括：
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 variable 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. 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 variable 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 multiple build bugs: #1262716, #1269063, #1269351, #1272723, #1272732, and #1253055.
Other bugs fixed: #1273101, #1272961, #1271264, and #1253055.
