Galera Cluster for MySQL 5.5.28-23.7 released

Last week Codership released a new version of Galera Cluster for MySQL: 5.5.28-23.7 (click to download)

This is a bug fix maintenance release. There are several significant fixes and users are recommended to upgrade.

Fixed:
- foreign keys support (multiple issues were fixed)
- thread counter going negative (and ensuing issues, like refusal to start new threads)
- causal reads timeout now returns ER_LOCK_WAIT_TIMEOUT.
- tables without primary key but with unique secondary key could cause crash with parallel applying.
- DDL in multi-statement transaction could cause a crash.
- aborted SELECTs were not automatically retried if aborted by DDL.
- RSU DDL could block.
- pt-table-checksum was not supported.
- CREATE TABLE... AS SELECT was not supported.
- queries were not retried after commit was canceled.
- MySQL slave could fail to start if no wsrep provider was loaded.
- mysqld_safe automatically restarted the node in case of failure.

New:
- automatic GTID recovery after crash in mysqld_safe.
- xtrabackup SST support.
- SST script interface now uses named parameters.
- SET PASSWORD is now replicated.
- updated to MySQL-5.5.28

Beta feature: with innodb_support_xa=OFF (default ON) there may be noticeable performance improvement (depends on load profile).

Galera Cluster for MySQL can be downloaded from our Launchpad repository.

Galera is also available with Percona XtraDB Cluster and MariaDB Galera Cluster.
