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

	Change	Effect

10	2nd middle parameter inputDevice has been removed from the interface signature.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Field defaultLowInputLatency has been added at the middle position of this structural type.	Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	Field defaultLowOutputLatency has been added at the middle position of this structural type.	Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
3	Field hostApi has been added at the middle position of this structural type.	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	14th parameter callback has been removed from the interface signature.	This parameter will be ignored by the interface.
2	9th parameter outputDriverInfo has been removed from the interface signature.	This parameter will be ignored by the interface.
3	12th parameter numberOfBuffers has been removed from the interface signature.	This parameter will be ignored by the interface.

	Change	Effect
1	Field defaultHighInputLatency 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 interfaces, otherwise it may result in crash or incorrect behavior of applications.
2	Field defaultHighOutputLatency 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 interfaces, otherwise it may result in crash or incorrect behavior of applications.
3	Field defaultSampleRate 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 interfaces, otherwise it may result in crash or incorrect behavior of applications.
4	Size of this type has been changed from 28 to 60 bytes.	Change of type size may lead to different effects. [+] ...

	Change	Effect
1	Type of 1st parameter stream has been changed from PortAudioStream* to PaStream*.	Replacement of parameter data type may indicate a change in the semantic meaning of this parameter.
