Updates and fixes in this version
- This release is mainly a bug-fix release.
- Codership changes: github.com/codership/mysql-wsrep/tree/5.6 (till commit c3fc46e).
- The Galera library used by MariaDB Galera Cluster and included in the MariaDB repositories is currently at version 25.3.19.
- As per the MariaDB Deprecation Policy, this will be the last release of MariaDB Galera Cluster 10.0 for Fedora 23, CentOS 5, RHEL 5, and openSUSE 13
- Running MariaDB Galera Cluster 5.5 and 10.0 nodes in a cluster is not supported (MDEV-6257)
- This version of MariaDB Galera Cluster supports
wsrepAPI v25 which means MariaDB Galera Cluster can be used with either a 25.2.x or 25.3.x Galera
wsrepprovider. A 25.3.x
wsrepprovider is included in the MariaDB repositories and is also available from the downloads page.
- 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).
Note: If Galera 25.2.x and 25.3.x are both being used in the cluster, MariaDB with Galera 25.3.x must be started with wsrep_provider_options='socket.checksum=1' in order to make it backward compatible with Galera v2. Galera wsrep providers other than 25.3.x or 25.2.x are not supported.
