Problems with Data Types, Medium Severity (5)

	Change	Effect
1	The pointer level of field single has been increased from 0 to 1.	The library functions may try to access unallocated memory by the dereferencing of old field value and therefore cause a crash of applications.

	Change	Effect
1	Size of field ref has been changed from 104 bytes to 92 bytes.	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

	Change	Effect
1	Size of field builtin has been changed from 92 bytes to 40 bytes.	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field may be broken.

	Change	Effect
1	Size of field lock has been changed from 76 bytes to 24 bytes.	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

	Change	Effect
1	Size of field multi has been changed from 104 bytes to 52 bytes.	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

Problems with Data Types, Low Severity (5)

	Change	Effect
1	Size of this type has been changed from 76 bytes to 24 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 144 bytes to 132 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 104 bytes to 52 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 92 bytes to 40 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 104 bytes to 92 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Constants (1)

	Change	Effect
1	The value of constant DFB_NUM_PIXELFORMATS has been changed from 31 to 35.	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.

Other Changes in Data Types (4)

	Change	Effect
1	The member DSPF_ARGB8565 with value 3246112 has been added.	No effect.
2	The member DSPF_AVYU with value 4295713 has been added.	No effect.
3	The member DSPF_VYU with value 3148834 has been added.	No effect.
4	The member DSPF_YUV444P with value 537922591 has been added.	No effect.
