Problems with Data Types, High Severity (1)

	Change	Effect
1	Field isValid has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

internalJSONNode.h
[+] class internalJSONNode (1)

to the top

Problems with Symbols, High Severity (1)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZNK16internalJSONNode7NullifyEb to _ZNK16internalJSONNode7NullifyEv. This may cause "undefined reference" linker error in old client applications.

internalJSONNode.h, libjson.so
[+] internalJSONNode::Nullify ( bool validation ) const (1)

to the top

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field _comment has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

internalJSONNode.h
[+] class internalJSONNode (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 48 bytes to 44 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
