Download on NuGet

• Breaking The default value for the UseAffectedRows connection string option has changed from true to false. This provides better compatibility with Connector/NET's defaults and also with other ADO.NET libraries: #600.
  • If you are upgrading from an earlier version of MySqlConnector, either audit your uses of the return value of ExecuteNonQuery (it will now return the number of rows matched by the WHERE clause for UPDATE statements, instead of the number of rows whose values are actually changed), or add UseAffectedRows=true to your connection string.
  • If you are migrating (or have recently migrated) from Connector/NET to MySqlConnector, then no changes need to be made: MySqlConnector now exhibits the same default behaviour as Connector/NET.
• Make MySqlException serializable: #601.
• Set MySqlException.Number to MySqlErrorCode.UnableToConnectToHost when connecting fails: #599.
• Populate MySqlException.Data dictionary: #602.
