Problems with Data Types, High Severity (1)

	Change	Effect
1	Field aligner has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

to the top

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Type of field opaque has been changed from unsigned char[136] (136 bytes) to unsigned char[256] (256 bytes).	1) This field may be incorrectly initialized or accessed by applications. 2) Size of the inclusive type has been changed.

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 144 bytes to 256 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
