	Change	Effect
1	Type of 1st parameter type has been changed from char (1 byte) to enum lo_type (4 bytes).	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, Low Severity (9)

	Change	Effect
1	Base type has been changed from struct _lo_blob* to void*.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Base type has been changed from struct _lo_message* to void*.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Base type has been changed from struct _lo_method* to void*.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Base type has been changed from int()(char const,char const,union lo_arg,int,void,void) to int()(char const,char const,union lo_arg*,int,lo_message,void).	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Base type has been changed from struct _lo_server* to void*.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Base type has been changed from struct _lo_server_thread* to void*.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Base type has been changed from struct _lo_target* to void*.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Size of this type has been changed from 4 bytes to 8 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	The pointer level of field s has been decreased from 1 to 0.	The library functions will treat the value of this field as the lower-dimension array and will not read all elements. This may change the behavior of applications.

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

1	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.

	Change	Effect
1	Type of 2nd parameter a has been changed from int to int32_t.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 1st parameter targ has been changed from lo_target to lo_address.	Replacement of parameter data type may indicate a change in its semantic meaning.
