MySQL 5.6.12 officially released a number of improvements

The major improvements of this version are as follows:

Mysql_upgrade improvement: now we will verify whether the compiled version matches the server version. If not, exit. You can use the -- version-check and -- skip-version-checking options to enable or disable version checks.

Compatibility fix: if the GRANT statement is used for an existing MySQL account, unexpected results may occur. This is because if the named account already exists, you cannot use the GRANT statement and the identified with clause to create a new user.

Important changes to Replication: if the server uses the -- binlog-ignore-db parameter and SELECTDATABASE () returns null to indicate that no database is selected currently), use dbname. statements using fully qualified table names in tblname format are not written into binary logs.
