Problems with Data Types, High Severity (1)

	Change	Effect
1	Field path 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.

cpml-segment.h
[+] struct _CpmlSegment (1)

to the top

Problems with Symbols, High Severity (1)

	Change	Effect
1	1st middle parameter distance has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

cpml-pair.h, libcpml-0.4.0.so
[+] cpml_pair_distance ( double* distance, CpmlPair const* from, CpmlPair const* to ) (1)

to the top

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field cairo_path 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.

cpml-segment.h
[+] struct _CpmlSegment (1)

to the top

Problems with Symbols, Medium Severity (4)

	Change	Effect
1	Parameter user_data of type gpointer has been added to the calling stack.	This parameter will not be initialized by old clients.

	Change	Effect
1	Type of return value has been changed from cairo_bool_t to double.	The return value became passed in different register. Applications will read the wrong memory block instead of the return value. Also, distribution of parameters on the available registers and stack may be changed.

	Change	Effect
1	Type of return value has been changed from cairo_bool_t (4 bytes) to void.	Applications will not obtain a return value and execution may change.

	Change	Effect
1	Parameter length of type double has been added to the calling stack.	This parameter will not be initialized by old clients.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Base type has been changed from *void()(AdgEntity,cairo_t) to void()(AdgEntity,cairo_t,gpointer)*.	Replacement of the base data type may indicate a change in its semantic meaning.

	Change	Effect
1	Field num_data 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 16 bytes to 12 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
3	Field original has been renamed to data.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

adg-entity.h
[+] typedef AdgCallback (1)

cpml-segment.h
[+] struct _CpmlSegment (3)

to the top

Problems with Symbols, Low Severity (5)

	Change	Effect
1	The pointer level of return value has been increased from 0 to 1.	Applications will treat the return value as the lower-dimension array and will not read all elements. This may change the behavior of applications.
2	Type of return value has been changed from cairo_bool_t to CpmlPair*.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 1st parameter vector has been changed from CpmlPair* to CpmlVector*.	Replacement of parameter data type may indicate a change in its semantic meaning.
2	The pointer level of return value has been increased from 0 to 1.	Applications will treat the return value as the lower-dimension array and will not read all elements. This may change the behavior of applications.
3	Type of return value has been changed from cairo_bool_t to CpmlVector*.	Replacement of return type may indicate a change in its semantic meaning.

Problems with Constants, Low Severity (3)

	Change	Effect
1	The constant CPML_DIR_DOWN with value (M_PI/2.) has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant CPML_DIR_RIGHT with value 0. has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant CPML_DIR_UP with value *(M_PI3./2.)** has been removed.	The value of this constant may no longer be properly handled by new-version library functions.
