Problems with Symbols, High Severity (2)

	Change	Effect
1	Middle parameter p1 of type mwChannelSet* 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.

	Change	Effect
1	Type of 3rd parameter msg_type has been changed from guint32 (4 bytes) to guint16 (2 bytes).	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 Data Types, Medium Severity (5)

	Change	Effect
1	Field start 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	Field state 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.
3	Field stop 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 service has been changed from 36 bytes to 48 bytes.	1) Size of the inclusive type has 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 Symbols, Medium Severity (3)

	Change	Effect
1	4th parameter text has been removed from the calling stack.	This parameter will be ignored by the function.

	Change	Effect
1	The pointer level of 1st parameter p1 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.
