Updates and fixes in this version

There was an important security fix included in the MariaDB Galera Cluster 5.5.51 release.
Please see the MariaDB 5.5.51 Release Notes and this blog post for more details.

  • This release is a bug-fix release.
  • The Galera library used by MariaDB Galera Cluster and included in the MariaDB repositories is currently at version 25.3.17.

Notes

  • 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 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.

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.
