Notable Changes

  • Out-of-cycle release to fix regressions in MariaDB 10.2.35
  • Follow up to MDEV-19838 to alter protocol checks to support the following implementations (which add garbage to the end of some packets):
    • PHP PDO (all versions) (MDEV-24121)
    • mysqlnd (from PHP < 7.3) (MDEV-24121)
    • mysql-connector-python (all versions) (MDEV-24134)
    • and mysql-connector-java (all versions)
  • The query optimizer consumed a lot of memory when handling construct in form of key_column [NOT] IN (large-list-of constants) (MDEV-24117)

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.
