## Notable Items

### Storage Engines

#### InnoDB

* Fatal InnoDB error: Unknown error Temp file write failure ([MDEV-36017](https://jira.mariadb.org/browse/MDEV-36017))
* AUTO\_INCREMENT leads to non-serializable on results ([MDEV-36330](https://jira.mariadb.org/browse/MDEV-36330))

### Data Definition - Alter Table

* 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](https://jira.mariadb.org/browse/MDEV-36852))

### Partitioning

* Server crashes in do\_mark\_index\_columns instead of ER\_DUP\_ENTRY on partitioned table ([MDEV-36817](https://jira.mariadb.org/browse/MDEV-36817))

### Data Definition - Create Table

* CREATE OR REPLACE with self-referencing CHECK hangs forever, cannot be killed ([MDEV-29155](https://jira.mariadb.org/browse/MDEV-29155))

### Server

* Segfault on INTERSECT ALL with UNION in Oracle mode ([MDEV-25158](https://jira.mariadb.org/browse/MDEV-25158))
* 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](https://jira.mariadb.org/browse/MDEV-36870))

### mariadb-backup

* 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](https://jira.mariadb.org/browse/MDEV-36143))

### Galera

* [Galera](https://app.gitbook.com/o/diTpXxF5WsbHqTReoBsS/s/3VYeeVGUV4AMqrA3zwy7/) updated to 26.4.23
* galera\_3nodes.inconsistency\_shutdown test occasionally hangs ([MDEV-36968](https://jira.mariadb.org/browse/MDEV-36968))
* Galera-26.4.23 corrects an incompatibility with OpenZFS >= 2.3.0 enabling the use of galera on this filesystem.

### Replication

* semi sync makes the master unresponsive when a replica is stopped ([MDEV-36934](https://jira.mariadb.org/browse/MDEV-36934))

### Authentication and Privilege System

* ALTER TABLE require ALTER privilege on sequence from DEFAULT value expression ([MDEV-36280](https://jira.mariadb.org/browse/MDEV-36280))

### Data Manipulation - Insert

* 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](https://jira.mariadb.org/browse/MDEV-37199))

### General

* Add [analyze\_max\_length](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#analyze_max_length) option to not collect statistics for long char/varchars ([MDEV-36536](https://jira.mariadb.org/browse/MDEV-36536))
* Packages for RHEL8 no longer depend on liburing. The RHEL8 kernel had insufficient kernel support so linking was an unneeded dependency. libaio was sufficient ([MDBF-1042](https://jira.mariadb.org/browse/MDBF-1042))
