Problems with Symbols, High Severity (2)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN13AlgorithmEnumC2EiPKc to _ZN13AlgorithmEnumD2Ev. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Medium Severity (3)

	Change	Effect
1	Field authAlgorithm 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 symEncAlgorithm 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.

Problems with Symbols, Medium Severity (5)

	Change	Effect
1	1st parameter cb has been removed from the calling stack.	This parameter will be ignored by the function.
2	2nd parameter id has been removed from the calling stack.	This parameter will be ignored by the function.
3	3rd parameter config has been removed from the calling stack.	This parameter will be ignored by the function.
4	4th parameter zidFilename has been removed from the calling stack.	This parameter will be ignored by the function.
5	5th parameter userData has been removed from the calling stack.	This parameter will be ignored by the function.

Problems with Data Types, Low Severity (2)

	Change	Effect
1	Size of this type has been changed from 44 bytes to 52 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 12 bytes to 16 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
