	Change	Effect
1	Size of v-table in this class has been changed from 92 bytes to 96 bytes.	The layout of v-tables in its subclasses has been changed. Call of any virtual method in subclasses may result in crash or incorrect behavior of applications.
2	Virtual method DBClientWithCommands::runCommand ( std::string const& dbname, BSONObj const& cmd, BSONObj& info, int options ) has been added to this class.	The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.
