Problems with Symbols, High Severity (2)

	Change	Effect
1	Parameter dims of type int has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Symbols, Medium Severity (2)

	Change	Effect
1	The pointer level of 2nd parameter result has been decreased from 2 to 1.	The library function will treat the parameter as the lower-dimension array and will not read all elements. This may change the behavior of applications. NOTE: if this is out-parameter then this change may cause a crash of applications.

Problems with Data Types, Low Severity (8)

	Change	Effect
1	Field Next 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 80 bytes to 88 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Symbols, Low Severity (8)

	Change	Effect
1	1st parameter geom has been renamed to out_buf.	Renaming of a parameter may indicate a change in its semantic meaning.
2	2nd parameter result has been renamed to geom.	Renaming of a parameter may indicate a change in its semantic meaning.
3	Base type of 1st parameter geom has been changed from gaiaGeomCollStruct (80 bytes) to gaiaOutBufferStruct (16 bytes).	Memory stored by pointer may be incorrectly initialized by applications.
4	Type of 2nd parameter result has been changed from char to gaiaGeomCollPtr**.	Replacement of parameter data type may indicate a change in its semantic meaning.
