Problems with Symbols, High Severity (5)

	Change	Effect
1	1st middle parameter config has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Type of 2nd parameter number has been changed from long (4 bytes) to long long (8 bytes).	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Parameter afs of type struct yajl_alloc_funcs* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
2	2nd middle parameter config has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
3	3rd middle parameter allocFuncs has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Data Types, Medium Severity (1)

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

yajl_parse.h
[+] enum yajl_status (1)

to the top

Problems with Data Types, Low Severity (5)

	Change	Effect
1	The member yajl_status_insufficient_data has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.

	Change	Effect
1	Base type of field yajl_integer has been changed from *int()(void,long)* to int()(void,long long).	Replacement of field base type may indicate a change in the semantic meaning of the field.
2	Base type of field yajl_map_key has been changed from int()(void,unsigned char const,unsigned int) to int()(void,unsigned char const,size_t).	Replacement of field base type may indicate a change in the semantic meaning of the field.
3	Base type of field yajl_number has been changed from int()(void,char const,unsigned int) to int()(void,char const,size_t).	Replacement of field base type may indicate a change in the semantic meaning of the field.
4	Base type of field yajl_string has been changed from int()(void,unsigned char const,unsigned int) to int()(void,unsigned char const,size_t).	Replacement of field base type may indicate a change in the semantic meaning of the field.

Problems with Symbols, Low Severity (6)

	Change	Effect
1	Type of 3rd parameter len has been changed from unsigned int* to size_t*.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 3rd parameter len has been changed from unsigned int to size_t.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 3rd parameter len has been changed from unsigned int to size_t.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of return value has been changed from unsigned int to size_t.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 4th parameter jsonTextLength has been changed from unsigned int to size_t.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 3rd parameter jsonTextLength has been changed from unsigned int to size_t.	Replacement of parameter data type may indicate a change in its semantic meaning.
