The DATETIME format contained an erroneous space. (Bug#41021)

If connection pooling was not set explicitly in the connection string, Connector/NET added “;Pooling=False” to the end of the connection string when MySqlCommand.ExecuteReader() was called.

If connection pooling was explicitly set in the connection string, when MySqlConnection.Open() was called it converted “Pooling=True” to “pooling=True”.

If MySqlCommand.ExecuteReader() was subsequently called, it concatenated “;Pooling=False” to the end of the connection string. The resulting connection string was thus terminated with “pooling=True;Pooling=False”. This disabled connection pooling completely. (Bug#40091)

If, when using the MySqlTransaction transaction object, an exception was thrown, the transaction object was not disposed of and the transaction was not rolled back. (Bug#39817)

When a prepared insert query is run that contains an UNSIGNED TINYINT in the parameter list, the complete query and data that should be inserted is corrupted and no error is thrown. (Bug#37968)
