Release Notes: This is a major bugfix and maintenance release. Upgrading is recommended. It fixed foreign keys support (multiple issues), a possible crash in tables without a primary key but with a unique secondary key, a crash with DDL in multi-statement transactions, a blocking problem in RSU DDL, a failure of MySQL slaves to start if no wsrep provider was loaded. It added automatic GTID recovery after a crash by mysqld_safe, xtrabackup SST support, and an update to MySQL 5.5.28.
Release Notes: This release fixes parallel applying with foreign keys and varchar keys certification. It also adds support for MySQL replication filters, skipping state transfer (wsrep_sst_method=skip), and a way to specify a list of potential peers for the mysqld_safe script.
Release Notes: This version is for MySQL 5.5.23. It fixed problems where ALTER TABLE RENAME and row deletion could conflict on slave, the slave could fail if the max_allowed_packet size was exceeded, the clustered index was not included in the key set, and locking sessions could deadlock multi-master. New experimental features were added: runtime consistency check support, hard crash GTID recovery, MyISAM storage engine support (incomplete), and Solaris 11 x86 build support.
Release Notes: This is a major maintenance release for the MySQL 5.5 series. It has upgraded to MySQL 5.5.20 and wsrep API v23. It has full foreign key support (requires Galera 2.0). It fixes a number of possible deadlocks involving MDL and GRL, fixes replication of view, trigger, event, function, and procedure definers, and fixes total order isolation for CREATE...SELECT... statement. It drops the usage of the InnoDB drop queue (a major consistency threat). It fixes slow query logging, fixes a self-crash due to "semaphore wait has lasted > 600 seconds" during rsync SST, and has many other bugfixes.
Release Notes: This is a maintenance release for the MySQL 5.1 series. It has been upgraded to MySQL 5.1.61 and wsrep API v23. It has full foreign key support (with Galera 2.0). It fixes total order isolation for the CREATE..SELECT statement, fixes a self-crash due to "semaphore wait has lasted > 600 seconds" during rsync SST, fixes replication of a function call result when called from SELECT, and has miscellaneous fixes and improvements in state transfer code.
Release Notes: This is a major bugfix release. Fixed bugs include a segfault on broken DDL, incompatibility with standard replication, mysqladmin not working when a node is not SYNCED, parallel applying broken on tables with no primary keys, deadlocks on NULL unique keys, bugs in state transfer, group communication, and others. MySQL has been updated to 5.1.59 and 5.5.17. New feature: Rolling Schema Upgrade.
Release Notes: Galera Cluster for MySQL milestone 1.0 reached. New in this release: support for both MySQL 5.5.15 and 5.1.58, on-disk writeset caching, strictly synchronous reads, improved stability in WAN, and Severalnines' ClusterControl(tm) GUI configurator and monitoring tool.
Release Notes: This release was updated for MySQL 5.1.58 and fixed problems where the secondary index was not fully supported, cascading foreign keys caused crashes in the InnoDB plugin, bad SST requests could destroy the database on the donor, and large LOAD DATA files were not supported. wsrep_cluster_name, wsrep_node_name, and wsrep_sst_* variables can now be changed at run-time.
Release Notes: This release fixed fast node restart, consensus timeout, and a segfault due to unresolvable cluster addresses.
Release Notes: SSL support and an arbitrator daemon were added. Old bugs that were fixed include an integer overflow on 32-bit platforms with dumps larger than 2Gb, a crash on group remerge under certain circumstances, failure of rsync SST when the MySQL data directory on the donor node contains files readable only by root, and omission of SSL support in the build of mysqld. Built-in InnoDB is no longer supported. The InnoDB plugin is loaded by default.
