This release of MariaDB Enterprise Server includes features backported from MariaDB Enterprise Server 10.6.
Enhanced consistency for Semi-Sync Replication
When , consistency is guaranteed for a Primary server in an HA (Primary/Replica) topology when using semi-synchronous replication. ()
Prior to this release, when using semi-synchronous replication, if a Primary crashed before sending a transaction to the Replica, on restart, the Primary could recover incomplete InnoDB transactions when rejoining as a Replica.
Galera updated to 25.3.34
ARM64 is now supported for several .
The script wsrep_sst_mariadb-backup checks all server-related configuration groups when processing a configuration file. ()
Prior to this release, only the [mysqld
When an statement is executed with ALGORITHM=INSTANT, a warning is not raised when the operation causes the default value of a DATE column to be truncated. ()
Possible server crash when pushing a WHERE condition over a mergeable derived table / view / CTE DT into a grouping view / derived table / CTE V whose item list contained set functions with constant arguments. ()
Server crashes on the second execution of a stored procedure or a prepared statement when the corresponding query executes a window function on a view, CTE, or derived table. ()
Server crashes are possible when executing a prepared statement with a hanging recursive CTE. ()
When fails after dropping the table, the DROP TABLE operation is not written into the binary log. ()
The statement does not quote role names properly for the DEFAULT ROLE. ()
The utility reports errors for freed pages. ()
As a result of this issue, a Joiner node writes the following error to the MariaDB Error Log:
With MariaDB Enterprise Cluster, when is set, rsync for a new SST process may be killed rather than the rsync for the old SST process. ()
With MariaDB Enterprise Cluster, the WSREP threads could write warnings about foreign keys to the MariaDB Error Log when wsrep_debug is not enabled. ()
In prior releases, the following warning could be written to the log:InnoDB: WSREP: referenced FK check fail: Lock wait index
information schema table added
information schema table added
system variable default value changed from DEFAULT to "" (empty)

The encryption plugin does not support key rotation, so key rotation checks are not required.
In previous releases, unnecessary key rotation checks with the plugin could reduce performance, unless they were explicitly disabled by setting .
