Problems with Data Types, Low Severity (2)

	Change	Effect
1	Value of member FEATURE_ENTRY_COUNT has been changed from 19 to 28.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Base type has been changed from __MIDL___MIDL_itf_wtypes_0003_0001 to __MIDL___MIDL_itf_wtypes_0000_0001_0001.	Possible incorrect initialization of parameters by applications.

Problems with Symbols, Low Severity (4)

	Change	Effect
1	Base type of parameter pClassSpec has been changed from __MIDL___MIDL_itf_wtypes_0003_0001 to __MIDL___MIDL_itf_wtypes_0000_0001_0001 of different format.	This parameter may be incorrectly initialized by applications.

	Change	Effect
1	Base type of parameter pClassSpec has been changed from __MIDL___MIDL_itf_wtypes_0003_0001 to __MIDL___MIDL_itf_wtypes_0000_0001_0001 of different format.	This parameter may be incorrectly initialized by applications.

	Change	Effect
1	Base type of parameter pClassspec has been changed from __MIDL___MIDL_itf_wtypes_0003_0001 to __MIDL___MIDL_itf_wtypes_0000_0001_0001 of different format.	This parameter may be incorrectly initialized by applications.

	Change	Effect
1	Type of 3rd parameter p3 has been changed from LPTSTR to LPSTR.	Replacement of parameter data type may indicate a change in its semantic meaning.

Problems with Constants (4)

	Change	Effect
1	The value of constant INET_E_ERROR_LAST has been changed from _HRESULT_TYPEDEF_(0x800C0300L) to _HRESULT_TYPEDEF_(0x800C0500L).	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.

	Change	Effect
1	The value of constant URLACTION_ACTIVEX_CURR_MAX has been changed from 0x00001206 to 0x0000120A.	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.

	Change	Effect
1	The value of constant URLACTION_SCRIPT_CURR_MAX has been changed from 0x00001407 to 0x00001408.	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.

	Change	Effect
1	The value of constant URLACTION_SHELL_CURR_MAX has been changed from 0x0000180B to 0x0000180D.	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.
