* Support for cursors on prepared statements ([MDEV-33830](https://jira.mariadb.org/browse/MDEV-33830))

### Replication

* Configurable defaults for `MASTER_SSL_*` settings for `CHANGE MASTER` ([MDEV-28302](https://jira.mariadb.com/browse/MDEV-28302))
* Fragment ROW replication events larger than `max_packet_size` ([MDEV-32570](https://jira.mariadb.com/browse/MDEV-32570))
* Improving performance of binary logging by removing the need of syncing it ([MDEV-34705](https://jira.mariadb.com/browse/MDEV-34705))

### Miscellaneous

* New hash algorithms for `PARTITION BY KEY` ([MDEV-9826](https://jira.mariadb.com/browse/MDEV-9826))

* Optimize ordered scans over `PARTITION BY RANGE` ([MDEV-37330](https://jira.mariadb.com/browse/MDEV-37330))

## Notable Items

### Galera

* The Galera package dependency has been removed from server packages and the Galera package is no longer included in the MariaDB repositories ([MDEV-38744](https://jira.mariadb.org/browse/MDEV-38744))

### 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](https://jira.mariadb.org/browse/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](https://jira.mariadb.org/browse/MDEV-35511))
