Add support of changing/adding any attribute in my.cnf. NB!!! It breaks backward compatibility for mysql.server state. Delete mysql_size param support (now you can customiza all my.cnf parameters in pillar) Add script import_users.py that create user pillar for existent server Add support root@localhost mysql user without password (root_password = False) Add support of grant_option
