Notable Items

SSL

  • The server no longer tolerates incorrectly configured SSL (MDEV-29811). If you have enabled SSL in my.cnf but have not configured it properly (for example, a certificate file is missing), MariaDB used to silently disable SSL, leaving you under impression that everything was fine and connections were secure. Since this release, MariaDB will fail to start if SSL is enabled, but cannot be switched on.

Backup

InnoDB

Galera

JSON

Replication

Repositories

  • Beginning with the next release (Q1 2023), our Yum, DNF, and Zypper repositories for Red Hat, Fedora, and SUSE will be migrated to being signed with a new GPG key. The key we are migrating to is the same one we already use for our Debian and Ubuntu Repositories.
    • The short Key ID is: 0xC74CD1D8
    • The long Key ID is: 0xF1656F24C74CD1D8
    • The full fingerprint of the key is: 177F 4010 FE56 CA33 3630 0305 F165 6F24 C74C D1D8
    • The key can be imported now in preparation for this change using the following command: 
sudo rpm --import https://supplychain.mariadb.com/MariaDB-Server-GPG-KEY

Docker Official Image

The following changes have been made to the docker.io/library/mariadb container image.

  • The number of gpg packages packages has been removed, leaving enough to apt-get update, but dirmngr that would fetch keys has been removed. (inspired by issue #469)
  • The environment variable LANG=C.UTF-8 has been added for those that exec into containers and copy paste UTF8 characters (fixes issue #468).
  • Adds OCI labels to image (fixes issue 436 and users need for version)
  • MariaDB config: skip-host-cache and skip-name-resolve moved to /etc/mysql/mariadb.conf.d/05-skipcache.cnf
