[3.0.0] - 2021-11-16

• Mysql.new no longer connect. use Mysql.connect or Mysql#connect.

• Mysql.init is removed. use Mysql.new instead.

• Mysql.new, Mysql.conncet and Mysql#connect takes URI object or URI string or Hash object. example: Mysql.connect('mysql://user:password@hostname:port/dbname?charset=ascii') Mysql.connect('mysql://user:password@%2Ftmp%2Fmysql.sock/dbname?charset=ascii') # for UNIX socket Mysql.connect('hostname', 'user', 'password', 'dbname') Mysql.connect(host: 'hostname', username: 'user', password: 'password', database: 'dbname')

• Mysql.options is removed. use Mysql#param = value instead. For example: m = Mysql.init m.options(Mysql::OPT_LOCAL_INFILE, true) m.connect(host, user, passwd) change to m = Mysql.new m.local_infile = true m.connect(host, user, passwd) or m = Mysql.connect(host, user, passwd, local_infile: true)

• Mysql::Time is removed. Instead, Time object is returned for the DATE, DATETIME, TIMESTAMP data, and Integer object is returned for the TIME data. If DATE, DATETIME, TIMESTAMP are invalid values for Time, nil is returned.

• meaningless methods are removed:

  • bind_result
  • client_info
  • client_version
  • get_proto_info
  • get_server_info
  • get_server_version
  • proto_info
  • query_with_result

• alias method are removed:

  • get_host_info: use host_info
