{% endhint %} [MariaDB 11.3](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/what-is-mariadb-113) is a previous rolling release. It is the first release in the new release model. From 11.3, we stop doing GA bug fix releases within each minor version. See [Adjusting the MariaDB Server release model](https://mariadb.org/adjusting-release-model) (mariadb.org). ## Upgrading * See [Upgrading Between Major MariaDB Versions](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/install-and-upgrade-mariadb/upgrading/platform-specific-upgrade-guides/upgrading-on-linux/upgrading-between-major-mariadb-versions) and [Upgrading from MariaDB 11.2 to MariaDB 11.3](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-to-unmaintained-mariadb-releases/upgrading-from-mariadb-11-2-to-mariadb-11-3). ## New Features & Improvements ### Connection Redirection * Added a [redirect mechanism](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/connection-redirection-mechanism-in-the-mariadb-clientserver-protocol) using the [redirect\_url](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#redirect_url) system variable ([MDEV-15935](https://jira.mariadb.org/browse/MDEV-15935)) * At the moment client-side support is missing ### InnoDB * Shrink [temporary tablespaces](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/innodb/innodb-tablespaces/innodb-temporary-tablespaces) without restart by setting the [innodb\_truncate\_temporary\_tablespace\_now](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/innodb/innodb-system-variables#innodb_truncate_temporary_tablespace_now) system variable. ([MDEV-28699](https://jira.mariadb.org/browse/MDEV-28699)) ### Replication * Add keywords "SQL\_BEFORE\_GTIDS" and "SQL\_AFTER\_GTIDS" for [START SLAVE UNTIL](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/standard-replication/gtid#sql_before_gtidssql_after_gtids) ([MDEV-27247](https://jira.mariadb.org/browse/MDEV-27247)).\ SQL\_BEFORE\_GTIDS stops the replica when it sees gtids of the option's argument list, without executing them. ### Data Types * It is now possible to create [partitions](https://mariadb.com/docs/server/reference/sql-statements/data-definition/alter/alter-table#partitions) on tables that contain [GEOMETRY types](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-structure/geometry/geometry-types) ([MDEV-19177](https://jira.mariadb.org/browse/MDEV-19177)) * [INET4](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/data-types/string-data-types/inet4) data types can now be cast into [INET6](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/data-types/string-data-types/inet6) types ([MDEV-31626](https://jira.mariadb.org/browse/MDEV-31626)) * This means INET4 values can be compared with INET6 values and can be inserted into INET6 columns;\ the server can automatically convert INET4 value into INET6 as needed. ### Functions * Values generated by the Key Derivation Function [KDF](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/secondary-functions/encryption-hashing-and-compression-functions/kdf) are resistant against password hashing generators, so are good for strongly hashed passwords ([MDEV-31474](https://jira.mariadb.org/browse/MDEV-31474)). #### Date and Time * [DATE\_FORMAT](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/date-time-functions/date_format) function can now print the current time zone abbreviation and current time zone offset from UTC with `%Z` and `%z` format specifiers. ([MDEV-31684](https://jira.mariadb.org/browse/MDEV-31684)) ### Optimizer * Queries like [UCASE(varchar\_col)=...](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/string-functions/upper) can now use an index on `varchar_col` if its collation is case insensitive. An [optimizer\_switch](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/optimization-and-tuning/query-optimizations/optimizer-switch) option, [sargable\_casefold=ON](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/optimization-and-tuning/query-optimizations/sargable-upper), has been added to enable this optimization. ([MDEV-31496](https://jira.mariadb.org/browse/MDEV-31496)) ### Privileges * Add a new database-level [privilege](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-statements/account-management-sql-statements/grant), `SHOW CREATE ROUTINE` that allows one to see the routine definition even if the user isn't the routine owner ([MDEV-29167](https://jira.mariadb.org/browse/MDEV-29167)) ### Processlist * Added a `SENT_ROWS` column to the [Information Schema PROCESSLIST](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/system-tables/information-schema/information-schema-tables/information-schema-processlist-table) table, as well as extended the display size for the columns in processlist to ensure\ that most results will fit in display ([MDEV-3953](https://jira.mariadb.org/browse/MDEV-3953)) ### OLD\_MODE * Setting a non-default [old\_mode](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/old_mode) value will now always issue a deprecation warning ([MDEV-31811](https://jira.mariadb.org/browse/MDEV-31811)) ### mariadb-backup * [mariadb-backup --innobackupex](https://mariadb.com/docs/server/server-usage/backup-and-restore/mariadb-backup/mariadb-backup-options#innobackupex) mode has been deprecated ([MDEV-31505](https://jira.mariadb.org/browse/MDEV-31505)) ### Spider * The [Spider](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/spider) storage engine now supports table options instead of having to encode them in COMMENT/CONNECTION strings. When any table option is specified, Spider will ignore COMMENT/CONNECTION strings at the same table/partition/subpartition. A new variable [spider\_ignore\_comments](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/spider/spider-system-variables#spider_ignore_comments) is introduced to ignore them globally at all levels (table/partition/subpartition). Another variable, [spider\_suppress\_comment\_ignored\_warning](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/spider/spider-system-variables#spider_suppress_comment_ignored_warning), is introduced to suppress warnings when Spider ignores COMMENT/CONNECTION strings. ([MDEV-28856](https://jira.mariadb.org/browse/MDEV-28856)) ### Removed The following deprecated features and system variables have been removed ([MDEV-32104](https://jira.mariadb.org/browse/MDEV-32104)): * sr\_YU [locale](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/data-types/string-data-types/character-sets/internationalization-and-localization/server-locale) (deprecated since [MariaDB 10.0.11](https://github.com/mariadb-corporation/docs-server/blob/test/release-notes/mariadb-community-server-release-notes/old-releases/release-notes-mariadb-11-3-rolling-releases/broken-reference/README.md)) * "engine\_condition\_pushdown" in [optimizer\_switch](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/optimization-and-tuning/query-optimizations/optimizer-switch) (deprecated since [MariaDB 10.1.1](https://mariadb.com/docs/release-notes/community-server/old-releases/10.1/10.1.1)) * [date\_format](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#date_format), [datetime\_format](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#datetime_format), [time\_format](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#time_format), [max\_tmp\_tables](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#max_tmp_tables) (deprecated since [MariaDB 10.1.2](https://github.com/mariadb-corporation/docs-server/blob/test/release-notes/mariadb-community-server-release-notes/old-releases/release-notes-mariadb-11-3-rolling-releases/broken-reference/README.md)) * [wsrep\_causal\_reads](https://app.gitbook.com/s/3VYeeVGUV4AMqrA3zwy7/reference/galera-cluster-system-variables#wsrep_causal_reads) (deprecated since [MariaDB 10.1.3](https://mariadb.com/docs/release-notes/community-server/old-releases/10.1/10.1.3)) * "parser" in [mroonga](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/mroonga) table comment (deprecated since [MariaDB 10.2.11](https://mariadb.com/docs/release-notes/community-server/old-releases/10.2/10.2.11)) ### Variables * For a list of all new variables, see [System Variables Added in MariaDB 11.3](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/optimization-and-tuning/system-variables/system-and-status-variables-added-by-major-release/system-and-status-variables-added-by-major-unmaintained-release/system-variables-added-in-mariadb-11-3). ## Security Vulnerabilities Fixed in [MariaDB 11.3](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/what-is-mariadb-113) For a complete list of security vulnerabilities (CVEs) fixed across all\ versions of MariaDB, see the [Security Vulnerabilities Fixed in MariaDB](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/security/cve)\ page. ## List of All [MariaDB 11.3](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/what-is-mariadb-113) Releases | Date | Release | Status | Release Notes | Changelog | | ----------- | -------------------------------------------------------------------------------------------------- | ----------- | ------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- | | 16 Feb 2024 | [MariaDB 11.3.2](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/11.3.2) | Stable (GA) | [Release Notes](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/11.3.2) | [Changelog](https://mariadb.com/docs/release-notes/community-server/changelogs/11.3/mariadb-11-3-2-changelog) | | 21 Nov 2023 | [MariaDB 11.3.1](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/11.3.1) | RC | [Release Notes](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/11.3.1) | [Changelog](https://mariadb.com/docs/release-notes/community-server/changelogs/11.3/mariadb-11-3-1-changelog) | | 20 Sep 2023 | [MariaDB 11.3.0](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/11.3.0) | Alpha | [Release Notes](https://mariadb.com/docs/release-notes/community-server/old-releases/11.3/11.3.0) | | {% hint style="info" %} Be notified of new MariaDB Server releases automatically by [subscribing](https://lists.mariadb.org/postorius/lists/announce.lists.mariadb.org/) to the MariaDB Foundation community announce 'at' lists.mariadb.org announcement list (this is a low traffic, announce-only list).
