Problems with Data Types, Low Severity 18

	Change	Effect
1	Size of this type has been changed from 1000 bytes to 1016 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field hash 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	Field mgf 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.
3	Size of this type has been changed from 72 bytes to 80 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
4	Field saltLen has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Size of this type has been changed from 3184 bytes to 3136 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 4264 bytes to 4200 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect

	Change	Effect
1	Field crlNumber 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 168 bytes to 184 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 32 bytes to 48 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 1200 bytes to 1216 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 248 bytes to 232 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 masterSecret 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.
3	The pointer level of field serverID 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.
