# MariaDB 10.4.9 Changelog

The most recent release of [MariaDB 10.4](https://github.com/mariadb-corporation/mariadb-docs/blob/main/release-notes/mariadb-community-server-release-notes/mariadb-community-server-release-notes/old-releases/release-notes-mariadb-10-4-series/README.md) is:[**MariaDB 10.4.34**](/docs/release-notes/community-server/old-releases/10.4/10.4.34.md) Stable (GA) [Download Now](https://downloads.mariadb.org/mariadb/10.4.34/)

After an upgrade MariaDB Server can crash if InnoDB tables exist with a `FULLTEXT INDEX` and a `FOREIGN KEY` constraint attached to them. We got reports that the crash already will be encountered on startup, but a crash is also possible at a later stage. See [MDEV-20987](https://jira.mariadb.org/browse/MDEV-20987) for more details.**Do not download or use this release.**
