完整列表请看 MariaDB Galera Cluster 10.0.22 Changelog.
Codership changes: github.com/codership/mysql-wsrep/tree/5.6 (till commit 21a2415).
The Galera library used by MariaDB Galera Cluster and included in the MariaDB repositories is currently at version 25.3.9.
MDEV-5146: Updates from LOAD DATA on a partitioned table were not getting replicated to other nodes in the cluster
MDEV-8208: A node could crash during startup
MDEV-8834: In a concurrent scenario, a session was able to write to a read_only node
不支持在集群中运行 MariaDB Galera Cluster 5.5 和 10.0 节点 (MDEV-6257)
This version of MariaDB Galera Cluster supports wsrep API v25 which means MariaDB Galera Cluster can be used with either a 25.2.x or 25.3.x Galera wsrep provider. A 25.3.x wsrep provider is included in the MariaDB repositories and is also available from the downloads page.
See the MariaDB 10.0.22 Release Notes and Changelog for more information on the changes in MariaDB.
On Ubuntu and Debian, the Galera Arbitrator daemon (garbd) and the galera library are in two separate packages. The packages are named galera-3 and galera-arbitrator-3. When installing MariaDB Galera Cluster on Ubuntu and Debian (the mariadb-galera-server package), the galera-3 package will be automatically installed. You can then install the arbitrator package on a separate node (recommended) or on one of the nodes running mariadb-galera-server (not recommended).
