Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Type of field key has been changed from unsigned char[32] (32 bytes) to unsigned char[64] (64 bytes).	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

	Change	Effect
1	Size of field b has been changed from 144 bytes to 176 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Parameter tz of type struct timezone const* has been added to the calling stack.	This parameter will not be initialized by old clients.

Problems with Data Types, Low Severity (5)

	Change	Effect
1	Size of this type has been changed from 144 bytes to 176 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 204 bytes to 236 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

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

	Change	Effect
1	Field enc_capa has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 564 bytes to 568 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Symbols, Low Severity (3)

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

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

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

Problems with Constants, Low Severity (2)

	Change	Effect
1	The value of constant IW_ENCODING_TOKEN_MAX has been changed from 32 to 64.	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 WIRELESS_EXT has been changed from 17 to 20.	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.
