Thestart_transaction()method now supports areadonlyargument. This argument can beTrueto start the transaction inREAD ONLYmode orFalseto start it inREAD WRITEmode. Ifreadonlyis omitted, the server's default access mode is used. For details about transaction access mode, see the description for theSTART TRANSACTIONstatement atSTART TRANSACTION, COMMIT, and ROLLBACK Statements. If the server is older than MySQL 5.6.5, it does not support setting the access mode and Connector/Python raises aValueError. (Bug #70545, Bug #17573172)

When using connection pooling, a connection returned to the pool was not reset, so session variables retained their values. Now these variables are reset by re-authenticating the user when the connection is returned to the pool. To disable this behavior, pass apool_reset_sessionargument toconnect()when requesting a pooled connection:

cnx = mysql.connector.connect(pool_reset_session=False,...)
