Notable Changes

Notable changes of this release include:

Atomic DDL

Replication, Galera and Binlog

  • The delay between binary log purges can now be specified with much greater precision. The system variable binlog_expire_logs_seconds is introduced as a form of alias for expire_logs_days, which now accepts a precision of 1/1000000 days (MDEV-19371)
  • Allow transition from unencrypted to TLS Galera cluster communication without cluster downtime (MDEV-22131)
  • DDL information logged on all Galera cluster nodes if wsrep_debug is set to SERVER and wsrep_OSU_method is 'TOI' (MDEV-9609)
  • For the mysqlbinlog / mariadb-binlog --base64-output option, removed the deprecated always option, and changed the default to auto (MDEV-25222)

Oracle Compatibility

Character Sets

  • The utf8 character set (and related collations) is now by default an alias for utf8mb3 rather than the other way around. It can be set to imply utf8mb4 by changing the value of the old_mode system variable (MDEV-8334)


  • For clients such as mysql / mariadb, the connection property specified via the command line (e.g. --port=3306) will now force its type (MDEV-14974)
