* CVSS base score
The systemd start and stop timeout for the MariaDB service is now set to 900 seconds (15 minutes). ()
For (Galera Library 25.3.29):
Setting was not effective because it was done after the socket was connected or accepted. The default value also caused TCP receive buffer auto-tuning to be disabled. This led to sub-optimal performance in high-bandwidth WAN clusters. The default value for has been changed to auto, which lets the kernel tune the TCP receive buffer. A new variable with a default value of auto
During a server restart, recovery could encounter an out-of-memory condition. A restart was only possible after increasing . ()
On a rollback of a large insert or update, or during a background task to purge transaction history after a large update or delete, the server could hang. ()
On a rollback or during a background task to purge transaction history due to a SPATIAL INDEX, the server could hang. ()
Executing or on tables could lead to an unexpected SQL Error (1118): Row size too large, when (default). ()
Queries that use window functions and implicit grouping could return wrong results. ()
Queries which use DISTINCT COUNT(*) OVER() in the expression returned wrong results. ()
Server could not be started when is set in a config file. (MENT-625)

Some components of MariaDB Enterprise Server might not support all platforms. For additional information, see "".
ALTER TABLE ... IMPORT TABLESPACE (MDEV-21513)Possible server crash if (default) is set and if the value for parameter pos in does not point to the beginning of an event in the binary log. (MDEV-18046)
A replication primary (master) running in semi-sync mode could crash when is executed, and the replica reconnects using the GTID protocol. (MDEV-19376)
could encounter a deadlock if a backup is taken from a replica with slave-parallel-threads is set to a value greater than 0 (MDEV-21255)
could crash when used in combination with FLUSH TABLES``and``UNLOCK TABLES``(MENT-438)
The aria_pack utility crashed when running an offline datafile compression on a table. (MDEV-14183)
Dropping a partition with and SESSION caused the MariaDB Enterprise Cluster (Galera) node to hang. (MDEV-21189)
With active optimizer trace (optimizer_trace='enabled=on') server could crash or the data of the optimizer trace could become corrupted. (MENT-614)
Inefficient thread handling in the thread pool, impacting any application that uses the thread pool. (MDEV-21343)
The MariaDB Enterprise Server config file mariadb-enterprise.cnf was not registered as a config file in RPM packages. (MENT-591)
ALTER USER IF EXISTS generated a SQL syntax error. (MENT-643)
A query using GROUP BY with an expression containing a field of a view could return wrong results. (MDEV-20922)
Running the script mysql_tzinfo_to_sql for MariaDB Enterprise Cluster could result in inconsistent timezone information across different nodes. (MDEV-21209)
Using the option with would cause it to run out of memory. (MDEV-20679)
For MariaDB Enterprise Cluster (Galera Library 25.3.29):
GCS delivered a JOIN message even if the node was in a DONOR state.
GCache could contain mixed histories from different clusters.
GComm socket timestamping/liveness checking produced false positives during replication of large transactions, which caused excessive amounts of broken connections.
Large transactions were able to monopolize bandwidth when segmentation was configured, causing delays in messages relayed by the segment representative. The fix implements fair queuing of messages.
Due to a bug in quorum computation, two primary conflicting components were formed when the group merged and partitioned again while the new primary view was forming.
A range plan was not always used for multi-join queries. (MDEV-21383)
