Problems with Data Types, High Severity (1)

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

speex_echo.h
[+] struct SpeexEchoState (1)

to the top

Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Type of field buf has been changed from char[20][2000] (40000 bytes) to char[20][1500] (30000 bytes).	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.
2	Field interp_frame has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

speex_jitter.h
[+] struct SpeexJitter (2)

to the top

Problems with Symbols, Medium Severity (1)

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

[+] speex_jitter_get ( SpeexJitter* jitter, short* out ) (1)

to the top

Problems with Data Types, Low Severity (7)

	Change	Effect
1	Size of this type has been changed from 76 bytes to 72 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field longterm_margin 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 loss_rate 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 shortterm_margin 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.
4	Size of this type has been changed from 40232 bytes to 30328 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
5	Field drop_frame has been renamed to lost_count.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.
6	Field underflow_count has been renamed to reset_state.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

speex_echo.h
[+] struct SpeexEchoState (1)

speex_jitter.h
[+] struct SpeexJitter (6)

to the top

Problems with Constants, Low Severity (1)

	Change	Effect
1	The value of constant SPEEX_JITTER_MAX_PACKET_SIZE has been changed from 2000 to 1500.	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.

speex_jitter.h
[+] SPEEX_JITTER_MAX_PACKET_SIZE

to the top

Other Changes in Constants (5)

	Change	Effect
1	The constant SPEEX_GET_LOOKAHEAD with value 39 has been added.	No effect.

	Change	Effect
1	The constant SPEEX_MODEID_NB with value 0 has been added.	No effect.

	Change	Effect
1	The constant SPEEX_MODEID_UWB with value 2 has been added.	No effect.

	Change	Effect
1	The constant SPEEX_MODEID_WB with value 1 has been added.	No effect.

	Change	Effect
1	The constant MAX_MARGIN with value 12 has been added.	No effect.
