Problems with Symbols, High Severity (1)

	Change	Effect
1	The pointer level of 3rd parameter ppvItems has been increased from 2 to 3.	The library function may try to access unallocated memory by the dereferencing of old parameter value and therefore cause a crash of applications.

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Size of field connectionChangeData has been changed from 24 bytes to 40 bytes.	Previous accesses of applications and library functions to this field may be broken.

Problems with Data Types, Low Severity (10)

	Change	Effect
1	Field hrConnectionFailedReason has been added to this type.	Size of the inclusive type has been changed. ATTENTION: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field ullNextConnectionId has been added to this type.	Size of the inclusive type has been changed. ATTENTION: 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 24 bytes to 40 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 sin6_addr has been changed from in6_addr to IN6_ADDR.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
2	Type of field sin6_family has been changed from short to ADDRESS_FAMILY.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
3	Type of field sin6_flowinfo has been changed from u_long to DWORD.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
4	Type of field sin6_port has been changed from u_short to USHORT.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
5	Field sin6_scope_id has been renamed to unnamed0.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Type of field Byte has been changed from u_char[16] to BYTE[16].	Replacement of the field data type may indicate a change in the semantic meaning of the field.
2	Type of field Word has been changed from u_short[8] to USHORT[8].	Replacement of the field data type may indicate a change in the semantic meaning of the field.

Problems with Symbols, Low Severity (6)

	Change	Effect
1	Type of 4th parameter phGraph has been changed from PHGRAPH to HGRAPH*.	Replacement of parameter data type may indicate a change in its semantic meaning.

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

	Change	Effect
1	Type of 2nd parameter pCount has been changed from PULONG to DWORD*.	Replacement of parameter data type may indicate a change in its semantic meaning.
2	Type of 3rd parameter ppvItems has been changed from PVOID* to PVOID**.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 7th parameter phGraph has been changed from PHGRAPH to HGRAPH*.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 4th parameter pEventRegistrations has been changed from PPEER_GRAPH_EVENT_REGISTRATION to PEER_GRAPH_EVENT_REGISTRATION*.	Replacement of parameter data type may indicate a change in its semantic meaning.
