Notes about this release
- MariaDB Galera Cluster 5.5.39 includes MariaDB 5.5.39 with Codership
4014) and Galera 25.3.5.
- 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 both 25.3.x and 25.2.x wsrep providers are available on the downloads page.
- wsrep_sst_rsync (sst script) in MariaDB Galera Cluster 5.5.39 uses
lsofwhich might not be installed by default on some linux distributions. It has to be installed if the wsrep_sst_method is set to
rsync(default). Package managers should be able to automatically resolve this dependency (MDEV-6264).
- There are now test packages available for MariaDB Galera Server in the
YUM and APT
Debian and Ubuntu, the package is called
mariadb-galera-test. On Red Hat, CentOS, and Fedora the package is called
MariaDB-Galera-test. These packages contain MTR framework and test suites along with some additional galera-specific suites which can be used for general testing of your MariaDB Galera Cluster installation, and for development.
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.
This release contains fixes for bugs, compiler errors/warnings and improvements in existing scripts.
A list of all the bugs fixed can be found in the changelog.
Thanks, and enjoy MariaDB Galera Cluster!
