Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been increased from 12 bytes to 16 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 neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Symbols, High Severity (13)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZNK8Echonest6Artist12fetchProfileE6QFlagsINS0_21ArtistInformationFlagEE to _ZNK8Echonest6Artist12fetchProfileENS_17ArtistInformationE. This may cause "undefined reference" linker error in old client applications.

This may cause "undefined reference" linker error in old client applications.

1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN8Echonest6Artist8topHotttE6QFlagsINS0_21ArtistInformationFlagEEiib to _ZN8Echonest6Artist8topHotttENS_17ArtistInformationEiib. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Type of return value has been changed from enum Analysis::AnalysisStatus (4 bytes) to QString (4 bytes).	1) The return value became passed in memory as the hidden first argument (address of the space on the stack provided by the caller) instead of the register and therefore the layout of parameter's stack has been shifted by 4 bytes. All the parameters will be incorrectly initialized by applications. 2) Applications will read the wrong memory block instead of the return value.

1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN8Echonest12AudioSummary14setAnalysisUrlERK7QString to _ZN8Echonest12AudioSummary14setAnalysisUrlERK4QUrl. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field details 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.
