Release Notes: This release fixes broken IST between 32-bit and 64-bt architectures, a possible cluster crash on arbitrator reconnect, and a number of other minor issues. It adds support for "shared" keys, a gcs.sync_donor boolean parameter to keep state donor temporally synced with the cluster (useful for non-blocking state transfers like xtrabackup and IST), and support for Solaris 11 (x86 only).
Release Notes: This release adds many critical bugfixes and updates. Upgrading is recommended.
Release Notes: This release fixes one long-standing and rare segfault in case of GCache ring buffer overruns, fixes a possible cluster crash/lock-up in case of network partitioning, and rejects unknown/mistyped parameters on initialization.
Release Notes: Big transactions would fail with the new replication protocol; this has been fixed. Minimum cached seqno in gcache has been added.
Release Notes: This is the first GA release in the Galera 3.x series. Major new features include the introduction of cluster "segments" to minimize WAN communication between data centers, an optimized writeset format, 128-bit write set checksums, and support for seamless interleaving of external replication events.
Release Notes: This is a major bugfix release. A lot of bugs were fixed since 2.4, some of which could result in a deadlock or other serious malfunctions. Upgrading is recommended.
