Problems with Data Types, Medium Severity (4)

	Change	Effect
1	Field dereverb_enabled 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.
2	Field reverb_decay 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.
3	Field reverb_estimate 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.
4	Field reverb_level 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 (3)

	Change	Effect
1	Base type has been changed from *int()(void,SpeexBits,short)* to *int()(void,SpeexBits,void)*.	Replacement of the base data type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type has been changed from *int()(void,short,SpeexBits)* to *int()(void,void,SpeexBits)*.	Replacement of the base data type may indicate a change in its semantic meaning.

	Change	Effect
1	Size of this type has been changed from 168 bytes to 184 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
