Problems with Data Types, Medium Severity 6

	Change	Effect
1	Field client 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.

	Change	Effect
1	Size of field area has been changed from 56 bytes to 64 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field may be broken.

Problems with Symbols, Medium Severity 2

	Change	Effect
1	Parameter whence of type int has been added to the calling stack.	This parameter will not be initialized by old clients.
2	Type of return value has been changed from int (4 bytes) to gint64 (8 bytes).	Applications will obtain a different return value and execution may change.

Problems with Constants, Low Severity 2

	Change	Effect
1	The value of constant VIPS_LIBRARY_AGE has been changed from (11) to (12).	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.

	Change	Effect
1	The value of constant VIPS_LIBRARY_CURRENT has been changed from (53) to (54).	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.
