## Notable Items
### MariaDB Cluster (Galera)
* A new `mariadb-server-galera` package now exists for Deb and RPM packages for ease of installing a galera system and pulling in its dependencies. Without galera, `mariadb-server` can be used
* Those on Galera systems will need to install `mariadb-server-galera` explicity as an upgrade from previous versions will result in galera dependencies being installed but not updated having a package dependency of MariaDB requiring them. Also the systemd service definations will not be galera-capable for bootstrap or SST transfers without the `mariadb-server-galera` package
* RPMs currently require explicit installation of `galera-4` along with the any dependencies used for SST, such as rsync, socat, lsof, grep, gawk, iproute, coreutils, findutils, and/or tar
* The `wsrep_info` plugin is installed by default with the `mariadb-server-galera` package
### Data Definition - Create Table
* On an error in `CREATE TEMPORARY TABLE ... SELECT`, InnoDB internally aborted a transaction, while the server thought the transaction still existed. This caused various inconsistencies in the binary log, disappearing savepoints, and more. The issue was fixed differently in different versions. In 10.11.16, 11.4.10, 11.8.6, and 12.2.2, the transaction is consistently and completely rolled back if `CREATE TEMPORARY TABLE ... SELECT` fails with an error. In 12.3.1, there is no rollback at all. ([MDEV-36787](https://jira.mariadb.org/browse/MDEV-36787))
### Plugin - Audit Log
* Audit log plugin will now log events for MariaDB Cluster (Galera) replication applier operations with a generic user name: ``. Before this change the user name in audit logs has been empty ([MDEV-35511](https://jira.mariadb.org/browse/MDEV-35511))
### Systemd
* Use of the `MYSQLD_OPTS` as an environment variable for systemd services is deprecated and will be removed in a later release. Place configuration option in configuration files

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://mariadb.com/docs/release-notes/community-server/12.3/12.3.2.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
