Problems with Data Types, Medium Severity (4)

	Change	Effect
1	Field n_dup_vars 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	Size of field constants has been changed from 560 bytes to 640 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.
3	Size of field vars has been changed from 4608 bytes to 5120 bytes.	1) Size of the inclusive type has been 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 (13)

	Change	Effect
1	Size of this type has been changed from 10820 bytes to 11416 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field use_count 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	Size of this type has been changed from 28 bytes to 32 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field constant_m 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 constant_n 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.
3	Field is_2d 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.
4	Size of this type has been changed from 7860 bytes to 8384 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field opcode_set has been renamed to opcode_major.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field get_asm_preamble has been added to this type.	This field will not be initialized by old clients. 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 load_constant has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Field load_dest 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 sampling_type 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.
3	Size of this type has been changed from 72 bytes to 80 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Constants, Low Severity (1)

	Change	Effect
1	The value of constant ORC_STATIC_OPCODE_ACCUMULATOR has been changed from 1 to (1<<0).	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.
