Problems with Data Types, Low Severity (7)

	Change	Effect
1	Size of this type has been changed from 216 bytes to 3968 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Base type of field buildMatrixCallback2 has been changed from void()(struct DmtxFinderBar) to void()(struct DmtxFinderBar,struct DmtxMatrixRegion*).	Replacement of field base type may indicate a change in the semantic meaning of the field.
3	Base type of field crossScanCallback has been changed from void()(struct DmtxScanRange,struct DmtxGradient,struct DmtxCrossScan) to void()(struct DmtxScanRange,struct DmtxGradient,struct DmtxEdgeScan).	Replacement of field base type may indicate a change in the semantic meaning of the field.
4	Base type of field finalCallback has been changed from *void()(float[3],float[3])** to void()(struct DmtxMatrixRegion).	Replacement of field base type may indicate a change in the semantic meaning of the field.
5	Base type of field followScanCallback has been changed from void()(struct DmtxFollower) to void()(struct DmtxEdgeFollower).	Replacement of field base type may indicate a change in the semantic meaning of the field.
6	Base type of field plotModuleCallback has been changed from void()(DmtxInfo,int,int,struct DmtxVector3) to void()(DmtxInfo,struct DmtxMatrixRegion*,int,int,struct DmtxVector3).	Replacement of field base type may indicate a change in the semantic meaning of the field.
7	Base type of field stepScanCallback has been changed from void()(struct DmtxScanRange,struct DmtxStepScan) to void()(DmtxInfo,struct DmtxScanRange,struct DmtxJumpScan*).	Replacement of field base type may indicate a change in the semantic meaning of the field.

Problems with Symbols, Low Severity (11)

	Change	Effect
1	2nd parameter line has been renamed to dir.	Renaming of a parameter may indicate a change in its semantic meaning.
2	3rd parameter direction has been renamed to lineNbr.	Renaming of a parameter may indicate a change in its semantic meaning.
3	Type of return value has been changed from void to int (4 bytes).	Replacement of return type may indicate a change in its semantic meaning.
4	Type of 3rd parameter direction has been changed from enum DmtxDirection to int.	Replacement of parameter data type may indicate a change in its semantic meaning.
5	Type of 2nd parameter line has been changed from int to enum DmtxDirection.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type of 2nd parameter func has been changed from void()(struct DmtxFinderBar) to void()(struct DmtxFinderBar,struct DmtxMatrixRegion*).	Replacement of parameter base type may indicate a change in its semantic meaning.
