Problems with Symbols, High Severity (1)

	Change	Effect
1	2nd middle parameter fAcceptPartialFailure has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

clusapi.h, clusapi.dll
[+] CreateCluster ( PCREATE_CLUSTER_CONFIG pConfig, BOOL fAcceptPartialFailure, PCLUSTER_MEMBERSHIP_CHANGE_PROGRESS pfnProgressCallback, PVOID pvCallbackArg ) (1)

to the top

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field lpszQuorumVolume has been removed from this type.	Applications will access incorrect memory when attempting to access this field.

clusapi.h
[+] struct _CREATE_CLUSTER_CONFIG (1)

to the top

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Parameter fdeleteVirtualComputerObjects of type BOOL has been added to the calling stack.	This parameter will not be initialized by old clients.

clusapi.h, clusapi.dll
[+] DestroyCluster ( HCLUSTER hCluster, PCLUSTER_MEMBERSHIP_CHANGE_PROGRESS pfnProgressCallback, PVOID pvCallbackArg ) (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Field fEmptyCluster has been added to this type.	ATTENTION: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

clusapi.h
[+] struct _CREATE_CLUSTER_CONFIG (1)

to the top

Problems with Symbols, Low Severity (2)

	Change	Effect
1	Base type of 3rd parameter pfnProgressCallback has been changed from *BOOL()(PVOID,CLUSTER_MEMBERSHIP_CHANGE_PHASE,DWORD,PCWSTR,DWORD) to BOOL()(PVOID,CLUSTER_SETUP_PHASE,CLUSTER_SETUP_PHASE_TYPE,CLUSTER_SETUP_PHASE_SEVERITY,DWORD,PCWSTR,DWORD)*.	Replacement of parameter base type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type of 2nd parameter pfnProgressCallback has been changed from *BOOL()(PVOID,CLUSTER_MEMBERSHIP_CHANGE_PHASE,DWORD,PCWSTR,DWORD) to BOOL()(PVOID,CLUSTER_SETUP_PHASE,CLUSTER_SETUP_PHASE_TYPE,CLUSTER_SETUP_PHASE_SEVERITY,DWORD,PCWSTR,DWORD)*.	Replacement of parameter base type may indicate a change in its semantic meaning.

[+] DestroyCluster ( HCLUSTER hCluster, PCLUSTER_MEMBERSHIP_CHANGE_PROGRESS pfnProgressCallback, PVOID pvCallbackArg ) (1)

to the top

Problems with Constants (1)

	Change	Effect
1	The value of constant CLUSREG_NAME_PHYSDISK_MAINTMODE has been changed from L"MainteanceMode" to L"MaintenanceMode".	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.
