InnoDB

• Remove innodb_defragment and related parameters (MDEV-30545)

Optimizer

• Semi-join optimization for single-table UPDATE/DELETE statements. Update and delete statements that use subqueries can now use all subquery optimization strategies that MariaDB offers, so now if you use subqueries in UPDATE or DELETE, these statements will likely be much faster (MDEV-7487)

• Queries with the DATE or YEAR functions comparing against a constant can now make use of indexes, so these will be noticeably quicker in certain instances. For example SELECT * FROM t2 WHERE YEAR(a) = 2019 or SELECT * FROM t2 WHERE DATE(a) <= '2017-01-01' (MDEV-8320)

General

• ALTER ONLINE TABLE - not released in the final MariaDB 11.1 (MDEV-16329)

JSON

• JSON_SCHEMA_VALID function for validating a JSON schema (MDEV-27128)

mariadb-backup

• Rename mariadb-backup’s xtrabackup_* files to mariadb_backup_* (MDEV-18931)
