Problems with Data Types, High Severity (2)

	Change	Effect
1	Field params 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.
2	Field update 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.

Problems with Data Types, Low Severity (9)

	Change	Effect
1	Field kbddriverdata has been added to this type.	1) This field will not be initialized by old clients. 2) 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	Field mousedriverdata has been added to this type.	1) This field will not be initialized by old clients. 2) 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.
