MariaDB 10.4.9 Release Notes

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 for more details.

Do not download or use this release.
