## Notable changes
Because this is the first release in the series, the changes are the full set of features added since [MariaDB Enterprise Server 11.8](/docs/release-notes/enterprise-server/11.8/whats-new.md). The highlights:
* [**MariaDB Raft Cluster**](/docs/release-notes/advanced-cluster.md) **0.9.1** — a replication provider built on the Raft consensus protocol, delivered as the `raft` plugin, with its own system variables, status variables, and `RAFT_*` Information Schema tables
* **Conflict Detection and Resolution** — `FOR CONFLICT` triggers that resolve row-based replication conflicts on the replica, with the new `ORG` row accessor for the primary's before-image ([MENT-2033](https://jira.mariadb.org/browse/MENT-2033))
* **Password-less authentication with TLS certificates** — the new `tls_certificate` authentication plugin, which authenticates a client from its TLS certificate against the account's `REQUIRE SUBJECT` clause ([MENT-2425](https://jira.mariadb.org/browse/MENT-2425))
* **Passphrase-protected TLS keys** — a private key protected by a passphrase can now be used, with the passphrase supplied through the [ssl\_passphrase](/docs/server/security/encryption/data-in-transit-encryption/ssltls-system-variables.md#ssl_passphrase) system variable
* [**Optimizer hints**](/docs/server/ha-and-performance/optimization-and-tuning/optimizer-hints.md) — inline hints for join order, index selection, subquery strategy, and execution time
* **InnoDB-based binary log** — binary log events can now be written to InnoDB-managed, page-structured files (`.ibb`) that are integrated with InnoDB's redo log and crash recovery, removing the costly two-phase commit between the binary log and InnoDB. Enabled with the read-only [binlog\_storage\_engine](/docs/server/ha-and-performance/standard-replication/replication-and-binary-log-system-variables.md#binlog_storage_engine) option ([MDEV-34705](https://jira.mariadb.org/browse/MDEV-34705))
* **Oracle compatibility** — [TO\_DATE()](/docs/server/reference/sql-functions/date-time-functions/to_date.md), [TO\_NUMBER()](/docs/server/reference/sql-functions/numeric-functions/to_number.md), [TRUNC()](/docs/server/reference/sql-functions/date-time-functions/trunc.md), [`( + )` outer join syntax](/docs/server/reference/sql-statements/data-manipulation/selecting-data/joins/join-syntax.md#oracle-mode), [cursors](/docs/server/reference/sql-statements/programmatic-compound-statements/programmatic-compound-statements-cursors.md) on prepared statements, and `SYS_REFCURSOR`
* **New GIS functions** — [ST\_Validate](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_validate.md), [ST\_IsValid](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_isvalid.md), [ST\_Simplify](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_simplify.md), [ST\_Collect](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_collect.md), [MBRCoveredBy](/docs/server/reference/sql-statements/geometry-constructors/mbr-minimum-bounding-rectangle/mbrcoveredby.md), [ST\_GeoHash](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_geohash.md), [ST\_LatFromGeoHash](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_latfromgeohash.md), [ST\_LongFromGeoHash](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_longfromgeohash.md), and [ST\_PointFromGeoHash](/docs/server/reference/sql-statements/geometry-constructors/miscellaneous-gis-functions/st_pointfromgeohash.md), improving MySQL 8 compatibility
* [**MariaDB Enterprise Audit**](/docs/server/reference/plugins/mariadb-enterprise-audit.md) — connection records now log the client port alongside the host, and connection events record the negotiated TLS version, on `DISCONNECT` and `CHANGE_USER` as well as `CONNECT` ([MENT-2470](https://jira.mariadb.org/browse/MENT-2470), [MENT-2471](https://jira.mariadb.org/browse/MENT-2471))
* [**Galera**](https://mariadb.com/docs/galera-cluster/) **26.4.27** — the replication library incorporated in this release for MariaDB Enterprise Cluster
For the complete list, see [What's New in MariaDB Enterprise Server 12.3](/docs/release-notes/enterprise-server/12.3/whats-new.md).
This release also includes the changes and improvements made in MariaDB Community Server 12.3, which are not all repeated here. For the upstream list, see [Changes and Improvements in MariaDB 12.3](/docs/release-notes/community-server/12.3/mariadb-12.3-changes-and-improvements.md).
## Changes in Storage Engines
* This release incorporates MariaDB ColumnStore engine version 25.10.7
## Incompatible Changes
The following keywords are now [reserved words](/docs/server/reference/sql-structure/sql-language-structure/reserved-words.md) and must be quoted if used as identifiers: `CONVERSION`, `TO_DATE`.
`ST_COLLECT` is not a reserved word, but as an aggregate function it is recognized as the built-in when it appears immediately before an opening parenthesis, so a stored function named `ST_Collect` can no longer be created or called by an unqualified name. The eight other new GIS functions are not affected this way. See [New Built-in Function Names](/docs/release-notes/enterprise-server/12.3/whats-new.md#new-built-in-function-names) for details.
The deprecated `big_tables`, `large_page_size`, and `storage_engine` system variables have been removed.
See [Incompatible Changes](/docs/release-notes/enterprise-server/12.3/whats-new.md#incompatible-changes) for details.
