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.
Release Notes: This is a major update over 0.7. Changes include improved flow control, parallel applying, configurability, scriptable state transfer, and notifications. The 0.8 series is protocol incompatible with 0.7 but retains most of the configuration options.
Release Notes: MySQL was updated to 5.1.53. Two reported group communication layer issues that led to spontaneous cluster unavailability were fixed. Miscellaneous small fixes and cleanups were done.
Release Notes: Updated to MySQL 5.1.47. AUTOCOMMIT query retrying has been fixed. Improved compatibility with stock binlog replication. Improved handling of tables without primary keys. Fixes for spontaneous disconnects in the transport layer. The RPM/deb structure was reworked to simplify installation.
Release Notes: The wsrep_cluster_address variable can now be set at run-time from any MySQL client to (re)initiate the connection to the cluster. LOAD DATA now supports datasets less than 1GB in size. Bugs were fixed. MySQL was updated to 5.1.43. RPM and DEB packages were provided for easier installation.
Release Notes: A node join operation could lead to a crash if the joining node were connected before the DB state transfer to joining node had started. This has been fixed. Loading a large MySQL dump file could lead to an out of memory situation if it contained LOCK statements and wsrep_convert_LOCK_to_trx was set to 1. Now by default, wsrep_convert_LOCK_to_trx is set to 0. This release has been updated to MySQL 5.1.42.
