	Change	Effect
1	Virtual method DBClientWithCommands::runCommand ( std::string const&, BSONObj const&, BSONObj&, int ) has been added to this class instead of DBClientWithCommands::runCommand ( std::string const&, BSONObj const&, BSONObj&, int, AuthenticationTable const* ).	Applications will pass parameters of older replaced method to newly added virtual method. This may result in crash or incorrect behavior of applications.
