Problems with Data Types, High Severity (9)

	Change	Effect
1	Size of this class has been increased from 156 bytes to 188 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	Size of this class has been changed from 28 bytes to 12 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been changed from 64 bytes to 96 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been changed from 144 bytes to 180 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been changed from 40 bytes to 72 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.
2	Virtual method DBClientWithCommands::setPostRunCommandHook ( DBClientWithCommands::PostRunCommandHookFunc ) 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.
3	Virtual method DBClientWithCommands::setRunCommandHook ( DBClientWithCommands::RunCommandHookFunc ) has been added to this class.	The layout of v-table has been changed.

Problems with Symbols, High Severity (2)

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN5mongo18DBClientReplicaSet8toStringEv to _ZNK5mongo18DBClientReplicaSet8toStringEv. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Medium Severity (3)

	Change	Effect
1	Size of field tags has been changed from 24 bytes to 8 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field may be broken.

	Change	Effect
1	Field _serverAddrString 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	Pure virtual method DBClientWithCommands::toString ( ) const has been added to this class instead of DBClientWithCommands::toString ( ).	Applications will provide an older method to the library instead of expected newely added virtual method. This may result in crash or incorrect behavior of applications.

Problems with Data Types, Low Severity (11)

	Change	Effect
1	Field _slaveOk has been renamed to _secondaryQueryOk.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Size of this type has been changed from 24 bytes to 8 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field _currentTag has been removed from this type.	Size of the inclusive type has been changed.
3	Field _isExhausted has been removed from this type.	Size of the inclusive type has been changed.
4	Field _tagIterator has been removed from this type.	Size of the inclusive type has been changed.

	Change	Effect
1	Field _postRunCommandHook has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field _runCommandHook has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Value of member MaxError has been changed from 11001 to 11602.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Field _abortOnFailure has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 16 bytes to 20 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of field _globalDomain has been changed from 16 bytes to 20 bytes.	Size of the inclusive type has been changed.
