Problems with Data Types, High Severity (3)

	Change	Effect
1	Field create 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 destroy 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.
3	Field modify 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, Medium Severity (3)

	Change	Effect
1	Field frame has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 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 mtdev has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
3	Type of field caps has been changed from touch_dev_caps (196 bytes) to touch_caps (32 bytes).	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Field state 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 224 bytes to 2088 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
3	The relative position of private field priv has been changed from 4 to 2.	Size of the inclusive type has been changed.
4	Field impl has been renamed to slot.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

Problems with Constants (1)

	Change	Effect
1	The value of constant DIM_GRAIL_PROP has been changed from 16 to 32.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
