allows database-specific and table-specific filters. (MENT-65) For example:
can be configured not to start the server if Audit Filters are invalid. (MENT-1243)
Added the new system variable.
To configure server startup to fail if Audit Filters are invalid, set to OFF and set server-audit to FORCE or FORCE_PLUS_PERMANENT.
This release of MariaDB Enterprise Server includes features backported from MariaDB Enterprise Server 10.5.

In alignment with the , MariaDB Enterprise Server 10.4.21-13 is provided for:
CentOS 7 (x86_64)
Debian 10 (x86_64, ARM64)

The default value of is ON, so the default behavior is the same as in prior releases.
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. (MDEV-21117)
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.
With this release, when using semi-synchronous replication and with rpl_semi_sync_slave_enabled=ON, incomplete transactions will be rolled-back on the Replica, ensuring the new Primary (former Replica) and new Replica (former Primary) remain in sync.
mysqldMariaDB Enterprise Backup expects to stream a backup using the included mbstream utility. (MDEV-15730)
Prior to this release, MariaDB Enterprise Backup expected , even though the xbstream utility had been renamed to mbstream.
InnoDB no longer acquires advisory file locks by default. (MDEV-24393)
The table has been added and can be used to view details about SQL keywords. (MDEV-25129)
The table has been added and can be used to view details about built-in functions. (MDEV-25129)
When using data-at-rest encryption with the encryption plugin, InnoDB will automatically disable key rotation checks. (MDEV-14180)
The encryption plugin does not support key rotation, so key rotation checks are not required.
In previous releases, unnecessary key rotation checks with the encryption plugin could reduce performance, unless they were explicitly disabled by setting .

With MariaDB Enterprise Cluster, when is set and log-bin and/or log-bin-index are set to custom paths, the rsync SST does not copy the binary log index. (MDEV-25978)
The "Condition pushdown into derived table" optimization cannot be applied if the expression being pushed refers to a derived table column, which is computed from an expression that has a stored function call, @session variable reference, or other similar construct. (MDEV-25969)
