New Features

• Add support for TYPE .. IS REF CURSOR (MDEV-10152)

  • In 13.0, REF CURSOR can be declared inside package routines and in a PACKAGE BODY, and used as a package routine local variable, package routine parameter, or package function RETURN type. It cannot yet be used as a parameter or RETURN type for global (non-package) routines.

• Support RECORD in routine parameters and function RETURN clause (MDEV-38768)

  • Same scope as REF CURSOR above: usable as a package routine parameter or package function RETURN type, not yet as a parameter or RETURN type for global (non-package) routines.

• Add init_rpl_role to SHOW VARIABLES output (MDEV-38202)

  • The replication role set via the --init-rpl-role startup option can now be queried with SHOW VARIABLES LIKE 'init_rpl_role' or SELECT @@init_rpl_role, instead of only being visible in the server's configuration file.

• One can specify timestamp format for the audit plugin log (MDEV-18386)

• Atomic CREATE OR REPLACE TABLE (MDEV-25292)

• Implement UPDATE ... RETURNING for single-table updates (MDEV-5092)

  • Combined with OLD_VALUE(), an application can read back both the pre- and post-update values of changed columns in one round trip, without a separate SELECT. Only single-table UPDATE supports RETURNING; multi-table UPDATE does not yet.

• INFORMATION_SCHEMA.SYSTEM_VARIABLES shows if a variable is deprecated (MDEV-35369)

  • Adds IS_DEPRECATED and DEPRECATED_REPLACEMENT columns, so tooling can query deprecation status directly instead of relying on release notes.

• INFORMATION_SCHEMA.STATISTICS and INFORMATION_SCHEMA.COLUMNS shows engine specific create options (MDEV-36444)

• Optimizer Trace includes used optimizer statistics (MDEV-36511)

• New innodb_log_archive variable makes InnoDB preserve the write-ahead log in a continuous sequence of files instead of overwriting a ring buffer, enabling point-in-time recovery and incremental backups (MDEV-37949)

  • mariadb-backup does not yet support the innodb_log_archive=ON log format, and fails if run against a server running with it enabled. See InnoDB Log Archiving and Point-in-Time Recovery for the manual procedure in the meantime.

• New QB_NAME() optimizer hint (MDEV-38045)

  • Every view, CTE, and derived table now automatically gets an implicit query block name based on its own alias, so hints can target objects inside them without adding an explicit QB_NAME() hint first.

  • A new locator form of QB_NAME(), QB_NAME(name, query_block_path), lets a hint specify a path to a query block nested inside a view, CTE, or derived table that isn't reachable by its implicit or explicit name alone.

• Reversed executable comments (MDEV-7381)

Notable Items

• CHANGE MASTER now resets Master_Server_Id in SHOW SLAVES STATUS (MDEV-15327)

• Faster unique indexes over CHAR columns in MEMORY tables (incl. temporary tables) (MDEV-21543)

• PERFORMANCE_SCHEMA now uses XXH3_128 hash for digest. Looks like MD5, but much faster and no problems in FIPS mode. (MDEV-31669)

• binlog_row_event_max_size default value was increased to 64k (MDEV-37608)

• default_master_connection can now be set on global level (MDEV-9247)
