Problems with Data Types, High Severity 1

	Change	Effect
1	Field closing has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

Problems with Data Types, Medium Severity 4

	Change	Effect
1	Field snapshot has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
2	Field restore_snapshot has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
3	Field is_snapshot_set has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

	Change	Effect
1	Field state has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

Problems with Data Types, Low Severity 5

	Change	Effect
1	Size of this type has been changed from 88 bytes to 64 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field ssltunnel_ostream 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 16744 bytes to 16752 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field accept has been renamed to accept_func.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field priority 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.
