Problems with Data Types, High Severity (3)

	Change	Effect
1	Size of this class has been increased from 140 bytes to 148 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Virtual method DBClientWithCommands::_auth ( BSONObj const& ) 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.
2	Virtual method DBClientWithCommands::auth ( std::string const&, std::string const&, std::string const&, std::string&, bool, enum Auth::Level* ) has been removed from this class.	The layout of v-table has been changed. Call of this virtual method or any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.

Problems with Symbols, High Severity (1)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN5mongo20DBClientWithCommands4authERKSsS2_S2_RSsbPNS_4Auth5LevelE to _ZN5mongo20DBClientWithCommands4authERKNS_7BSONObjE. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Medium Severity (3)

	Change	Effect
1	Field _lastReadPref has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	The layout of v-table has been changed for unknown reason.	Call of any method in this class may result in crash or incorrect behavior of applications.

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Type of field authCache has been changed from std::map<std::string,std::pair<std::string,std::string> > to std::map<std::string,BSONObj>.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
