MariaDB Enterprise Server 5.5.44 Release Notes

This version of MariaDB Enterprise Server is built off MariaDB 5.5.44. 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.

Notable Changes

  • As always with MariaDB Enterprise Server, additional testing and checks have been done to ensure the highest quality.
  • XtraDB updated to 5.5.42-37.2
  • TokuDB updated to version 7.5.7
  • Client command line option --ssl-verify-server-cert (and MYSQL_OPT_SSL_VERIFY_SERVER_CERT option of the client API) when used together with --ssl will ensure that the established connection is SSL-encrypted and the MariaDB server has a valid certificate. This fixes CVE-2015-3152.

MariaDB Enterprise Cluster 5.5.44 Release Notes

This version of MariaDB Enterprise Cluster is built off MariaDB Galera Cluster 5.5.44 and is mainly an upgrade to benefit from many fixes and improvements in MariaDB Galera 5.5.43, including some backported fixes, as detailed in the changelog.

Updates and fixes in this version

  • Codership changes: github.com/codership/mysql-wsrep/tree/5.5 (till commit 11dc27f)
  • Fix for MDEV-8115: mysql_upgrade crashes the server with REPAIR VIEW
  • The following FLUSH commands are now executed under total order isolation:
    • FLUSH DES_KEY_FILE
    • FLUSH HOSTS
    • FLUSH PRIVILEGES
    • FLUSH QUERY CACHE
    • FLUSH STATUS
    • FLUSH USER_RESOURCES

Notable 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 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.
