Problems with Data Types, High Severity (2)

	Change	Effect
1	Size of this class has been increased from 1016 bytes to 1020 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.

Problems with Data Types, Low Severity (3)

	Change	Effect
1	Field ping_ 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 112 bytes to 116 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field failed_ 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.
