	Change	Effect
1	Base class AllocatedObject<0> has been removed.	1) Size of the class has been changed from 80 bytes to 72 bytes. 2) The memory layout in this class has been shifted by 16 bytes.
2	Base class WorkQueue::ResponseHandler has been removed.	1) The layout of v-table in this class has been changed. 2) Size of the class has been changed from 80 bytes to 72 bytes. 3) The memory layout in this class has been shifted by 16 bytes.
3	Size of this class has been changed from 80 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.
4	Virtual method canHandleRequest ( WorkQueue::Request const, WorkQueue const ) 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.
5	Virtual method canHandleResponse ( struct WorkQueue::Response const, WorkQueue const ) 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.
