Security

Upgrading from 10.2 versions earlier than 10.2.17 is highly recommended
for all Galera users due to bug MDEV-12837 which caused serious stability
issues with earlier versions. See the bug issue page for more information.

When upgrading from MariaDB 10.2.16 or earlier to MariaDB 10.2.17 or higher,
running mysql_upgrade is required due to changes introduced in MDEV-14637.

MongoDB protocol support files for the CONNECT engine are missing in this release.
If you want to use CONNECT engine with MongoDB, you need to download
Mongo2.jar or Mongo3.jar and put a path to this file into the connect_class_path in the my.cnf.
