MariaDB Enterprise Server 5.5.45 Release Notes
This version of MariaDB Enterprise Server is built off MariaDB 5.5.45. We are now providing only 64-bit x86 (x86-64) linux packages, 32-bit x86 Linux packages have been discontinued. We have ended support for Fedora 19, Fedora 20, OpenSuse 13.1 and Ubuntu 10.04 LTS (Lucid) packages.
In most respects MariaDB Enterprise will work exactly as MySQL: all commands, interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.
Noteable Changes
MariaDB 5.5.45 is a maintenance release. It includes several bugfixes and updates, including from MySQL 5.5.45. Notable updates include:
- XtraDB updated to 5.5.44-37.3
- Diffie-Helman modulus increased to 2048 bits (MDEV-8352)
- Add mysqlbinlog --binlog-row-event-max-size support (MDEV-8340)
MariaDB Enterprise Cluster 5.5.45 Release Notes
This version of MariaDB Enterprise Cluster is built off MariaDB Galera Cluster 5.5.45 and is mainly an upgrade to benefit from many fixes and improvements in MariaDB Galera 5.5.44, including some backported fixes, as detailed in the changelog.

Noteable Changes
- 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 Galerawsrep
provider. A 25.3.xwsrep
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.
