Notable Changes

  • When creating a connection, the tls_version connection attribute can be specified to select a version of the TLS protocol. (CONPY-253)

    • For example, to specify the connection attribute to the mariadb.connect() method:

      conn = mariadb.connect(

Issues Fixed

  • When a numeric column has the ZEROFILL option set, a ValueError exception is raised for values that have 2 or more leading zeros. (CONPY-258)

  • When the pool.get_connection() method is called and all connections are in use, None is returned. (CONPY-255)

    • Starting with this release, a PoolError exception is raised in this scenario to better match the behavior of other Python database drivers.

  • When the pool.get_connection() method is called, the same connection can be returned twice. (CONPY-256)
