Notable Items

MariaDB Cluster (Galera)

• A new mariadb-server-galera package now exists for Deb and RPM packages for ease of installing a galera system and pulling in its dependencies. Without galera, mariadb-server can be used

• Those on Galera systems will need to install mariadb-server-galera explicitly as an upgrade from previous versions will result in galera dependencies being installed but not updated having a package dependency of MariaDB requiring them. Also the systemd service definitions will not be galera-capable for bootstrap or SST transfers without the mariadb-server-galera package

• RPMs currently require explicit installation of galera-4 along with the any dependencies used for SST, such as rsync, socat, lsof, grep, gawk, iproute, coreutils, findutils, and/or tar

• The wsrep_info plugin is installed by default with the mariadb-server-galera package

Data Definition - Create Table

• On an error in CREATE TEMPORARY TABLE ... SELECT, InnoDB internally aborted a transaction, while the server thought the transaction still existed. This caused various inconsistencies in the binary log, disappearing savepoints, and more. The issue was fixed differently in different versions. In 10.11.16, 11.4.10, 11.8.6, and 12.2.2, the transaction is consistently and completely rolled back if CREATE TEMPORARY TABLE ... SELECT fails with an error. In 12.3.1, there is no rollback at all. (MDEV-36787)

Plugin - Audit Log

• Audit log plugin will now log events for MariaDB Cluster (Galera) replication applier operations with a generic user name: <wsrep_applier>. Before this change the user name in audit logs has been empty (MDEV-35511)

Systemd

• Use of the MYSQLD_OPTS as an environment variable for systemd services is deprecated and will be removed in a later release. Place configuration option in configuration files

General

• As per the MariaDB Deprecation Policy, this will be the last release of MariaDB 12.3 for OpenSUSE Leap 15.6, Ubuntu 25.10 "Questing Quokka", Ubuntu 25.04 "Plucky Puffin", and Fedora 42
