Problems with Symbols, Medium Severity (3)

	Change	Effect
1	Size of this global data has been changed from 8 bytes to 12 bytes.	Applications will obtain a different value and execution may change.
2	Type of this global data has been changed from *SpeexMode[2] (8 bytes) to SpeexMode[3]* (12 bytes).	Applications will obtain a different value and execution may change.

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

Problems with Data Types, Low Severity (11)

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

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

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

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

	Change	Effect
1	Field buf_size has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field overflow has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Field reserved1 has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
4	Field reserved2 has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
5	Size of this type has been changed from 20 bytes to 36 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field extra_headers has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field speex_header_version has been renamed to speex_version_id.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

Problems with Constants, Low Severity (2)

	Change	Effect
1	The value of constant SPEEX_NB_MODES has been changed from 2 to 3.	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 MAX_BYTES_PER_FRAME has been changed from 1000 to 2000.	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.
