Problems with Data Types, High Severity (7)

	Change	Effect
1	Size of this class has been changed from 36 bytes to 40 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 v-table in this class has been changed from 136 bytes to 144 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	Pure virtual method DBClientBase::killCursor ( long long cursorID ) has been added to this class.	1) Applications will not provide the implementation for this pure virtual method and therefore cause a crash in the library trying to call this method. 2) 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.

Problems with Symbols, High Severity (2)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN5mongo20DBClientWithCommands16createCollectionERKSsjbiPNS_7BSONObjE to _ZN5mongo20DBClientWithCommands16createCollectionERKSsxbiPNS_7BSONObjE. This may cause "undefined reference" linker error in old client applications.
