Problems with Symbols, High Severity (1)

	Change	Effect
1	Type of 2nd parameter portnum has been changed from unsigned short (2 bytes) to unsigned int (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 (7)

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

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

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

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

	Change	Effect
1	Base type has been changed from *void()(void,ne_buffer) to void()(ne_request,void,ne_buffer)**.	Possible incorrect initialization of parameters by applications.

	Change	Effect
1	Type of field port has been changed from int to unsigned int.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Type of field reason_phrase has been changed from char const* to char*.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

Problems with Symbols, Low Severity (5)

	Change	Effect
1	Base type of 2nd parameter fn has been changed from *void()(void)* to *void()(ne_request,void)**.	Replacement of parameter base type may indicate a change in its semantic meaning.

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

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

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

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

[+] ne_uri_defaultport ( char const* scheme ) (1)

Problems with Constants (3)

	Change	Effect
1	The value of constant NE_SOCK_CLOSED has been changed from -3 to (-3).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant NE_SOCK_ERROR has been changed from -1 to (-1).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant NE_SOCK_TIMEOUT has been changed from -2 to (-2).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
