Mysql：Changes in MySQL 5.6.22 (2014-12-01, General Availability)：【sql-log-bin】

Replication: The global scope for the sql_log_bin system variable has been deprecated, and this variable can now be set with session scope only. The statement SET GLOBAL SQL_LOG_BIN now produces an error. It remains possible to read the global value of sql_log_bin, but doing so produces a warning. You should act now to remove from your applications any dependencies on reading this value; the global scope sql_log_bin is removed in MySQL 8.0. (Bug #67433, Bug #15868071)

Replication: The variable binlogging_impossible_mode now has an alias named binlog_error_action, which is the preferred name. binlogging_impossible_mode is now deprecated. (Bug #19507567)
