Problems with Data Types, High Severity (7)

	Change	Effect
1	Size of this class has been changed from 4 bytes to 20 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.
2	Virtual method Decoder::getNumExtraBands ( ) const has been added to this class.	The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.
3	Virtual method Decoder::getPosition ( ) const has been added to this class.	The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.

	Change	Effect
1	Size of this class has been increased from 24 bytes to 48 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Medium Severity (5)

	Change	Effect
1	Virtual method Encoder::setICCProfile ( Encoder::ICCProfile const& ) has been added to this class.	The layout of v-table has been changed. This leaf class has no exported constructors and therefore applications will copy an old v-table of the class that will not contain a pointer to added virtual method. Call of any method in this class may result in crash or incorrect behavior of applications. NOTE: if new virtual method is called only from other new methods, then binary compatibility should not be affected.
2	Virtual method Encoder::setYResolution ( float ) has been added to this class.	The layout of v-table has been changed. This leaf class has no exported constructors and therefore applications will copy an old v-table of the class that will not contain a pointer to added virtual method. Call of any method in this class may result in crash or incorrect behavior of applications. NOTE: if new virtual method is called only from other new methods, then binary compatibility should not be affected.

	Change	Effect
1	Value of member DOUBLE has been changed from 4 to 6.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	Value of member FLOAT has been changed from 3 to 5.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
3	Value of member INT32 has been changed from 2 to 3.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
