Problems with Symbols, High Severity (1)

	Change	Effect
1	Type of 2nd parameter limit has been changed from apr_size_t (4 bytes) to apr_uint64_t (8 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, Medium Severity (5)

	Change	Effect
1	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.
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 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.

	Change	Effect
1	Field ssltunnel_ostream 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.

	Change	Effect
1	Field priority 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 44 bytes to 32 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
