MariaDB 13.0

MariaDB Community Server 13.0 reached General Availability on September 17, 2026, moving the 13.0 series from Release Candidate to Stable. The release expands SQL and Oracle compatibility and rounds out storage-engine capabilities.

New Features

• UPDATE RETURNING adds a RETURNING clause to UPDATE, mirroring behavior that has long been available on INSERT.
• Improved Optimizer Trace gives deeper visibility into query-plan decisions.
• InnoDB log archiving supports archiving redo log segments, easing incremental backup workflows.
• Oracle compatibility grows with RECORD support in routine parameters and function RETURN clauses, plus TYPE support in routine bodies.
• Atomic CREATE OR REPLACE TABLE makes table swaps atomic, and SHOW now exposes init_rpl_role.

Security and Fixes

The stable release bundles fixes for several security issues carried earlier in the release-candidate line, along with stability corrections across replication and the audit plugin.

Migration

Existing 12.x users can move to 13.0 through the standard major-version upgrade path. Review the release notes for changed defaults in the optimizer and server initialization before deploying.
