Includes MariaDB 5.5.36 and Galera

MariaDB Galera Cluster 5.5.36 includes MariaDB 5.5.36 with Codership additions (lp:codership-mysql/5.5 till revision 3944) andGalera 25.3.2. 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 Galerawsrep provider. A 25.3.x wsrep provider is included in the MariaDB repositories and both 25.3.x and 25.2.x wsrep providers are available on the downloads page.

See the MariaDB 5.5.36 Release Notes andChangelog for more information on the changes in MariaDB.

Important : While upgrading the nodes of a MariaDB Galera cluster care must be taken when using different versions of Galera library (wsrep provider). A MariaDB Galera cluster node with Galera version 3 (25.3.xx) might fail to join an existing cluster running with Galera 2 (25.2.xx) nodes. This happens due to difference in the default values of 'socket.checksum' for Galera 2 and Galera 3 libraries. So, in order to fix this, the node with Galera 3 should be started with an additional wsrep provider option: socket.checksum=1 in order to make it backward compatible with nodes running with Galera 2. For example:

--wsrep_provider_options='socket.checksum=1; [other provider options; ...]'
