Problems with Symbols, High Severity (8)

	Change	Effect
1	Parameter ctx of type scmp_filter_ctx const 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.

1	Parameter ctx of type scmp_filter_ctx const has been added to the calling stack.	This parameter will not be initialized by old clients.

Problems with Symbols, Low Severity (2)

	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 int to scmp_filter_ctx.	Replacement of return type may indicate a change in its semantic meaning.
