MariaDB 13 Expands Oracle Compatibility, Improves Developer Experience and Observability

MariaDB Community Server 13.0 reached GA status. It adds native support for REF CURSOR and RECORD in procedure parameters, a RETURNING clause for UPDATE with OLD_VALUE(), improved optimizer hints, and observability via I_S tables. The next LTS is MariaDB 13.3.

• Support for REF CURSOR and RECORD in procedure parameters and return values
• RETURNING for UPDATE with OLD_VALUE() gives old and new values in one query
• Optimizer hints automatically bind to Views, CTEs, and derived tables
• init_rpl_role became a system variable; CREATE_OPTIONS added to I_S.STATISTICS and I_S.COLUMNS
