1.4.0-beta.4

• Breaking Remove ConnectionIdlePingTime: #1042.
  • The Connection Idle Ping Time connection string option is still accepted, but has no effect.
  • If Connection Reset = False, MySqlConnection.Open will return a pooled connection (if one is available) without testing it for liveness (by pinging the server). This improves performance but may degrade reliability. (Connection Reset = True, which is the default, is still recommended for greatest reliability.)
  • If the server has closed the pooled connection, MySqlConnection.Open will succeed, but the first operation on that connection will fail. Command execution should be wrapped in a try/catch/retry loop to handle this scenario.
• Add more values to MySqlErrorCode: #1048.
• Fix bug executing stored procedures with backticks in their names: #1029.
• Remove inner exception for UnableToConnectToHost exception: #1035.
• Fix rare ObjectDisposedException that could be thrown when a connection timeout occurred.
• Reword "recovering leaked sessions" log message.
