Download Release Notes Changelog Overview of Enterprise Server 10.6

Release date: 8 Sep 2025

MariaDB Enterprise Server 10.6.23-19 is a maintenance release of MariaDB Enterprise Server 10.6. This release includes a variety of fixes.

Changes in Storage Engines

  • This release incorporates MariaDB ColumnStore engine version 23.10.6

Notable changes

Issues Fixed

Can result in data loss

  • Adding (with ALTER TABLE) a UNIQUE constraint that is USING HASH to a table with foreign keys could've caused the table to become corrupted. (MDEV-36852)

Can result in hang or crash

  • Server crashes in do_mark_index_columns instead of ER_DUP_ENTRY on partitioned table (MDEV-36817)

  • CREATE OR REPLACE with self-referencing CHECK hangs forever, cannot be killed (MDEV-29155)

  • Segfault on INTERSECT ALL with UNION in Oracle mode (MDEV-25158)

  • This commit fixes a bug where Aria tables are used in (master->slave1->slave2) and a backup is taken on slave2. In this case it is possible that the replication position in the backup, stored in mysql.gtid_slave_pos, will be wrong. This will lead to replication errors if one is trying to use the backup as a new slave. (MDEV-36143)

  • Fatal InnoDB error: Unknown error Temp file write failure (MDEV-36017)

  • semi sync makes the master unresponsive when a replica is stopped (MDEV-36934)

  • json_extract crashes in Item_func_json_extract::read_json (MDEV-21530)

  • Inconsistency detected - create sequence (MENT-2297)

  • Replica stops with "Found invalid event in binary log" (MENT-2385)

Can result in unexpected behaviour

  • ALTER TABLE require ALTER privilege on sequence from DEFAULT value expression (MDEV-36280)

  • In certain cases privileges on sequences were too restrictive, for example, SELECT on a table might've erroneously required INSERT privilege on a sequences (MDEV-36870)

  • AUTO_INCREMENT leads to non-serializable on results (MDEV-36330)

  • UNIQUE constraint that was USING HASH and UNIQUE constrant WITHOUT OVERLAPS could be violated under heavy load in READ COMMITTED transaction isolation mode. (MDEV-37199)

  • UNIQUE KEY USING HASH accepting duplicate records (MENT-2324)
