Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Value of member DMT_ALL has been changed from 127 to 255.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

Problems with Data Types, Low Severity (12)

	Change	Effect
1	Field fatal_messages 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 log_delay_min_loops 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 log_delay_min_us 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	Field log_delay_rand_loops 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.
5	Field log_delay_rand_us 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.
6	Field perf_dump_interval 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.
7	Size of this type has been changed from 192 bytes to 216 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Value of member DFB__RESULT_END has been changed from 368681517 to 368681518.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Field priority 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 stack_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.
3	Field trace_buffer 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 112 bytes to 124 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Constants, Low Severity (2)

	Change	Effect
1	The value of constant FUSION_BUILD_KERNEL has been changed from (0) to (1).	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 DFB_NUM_PIXELFORMATS has been changed from 41 to 42.	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 Constants (4)

	Change	Effect
1	The constant DIRECT_BUILD_GCC_ATOMICS with value (0) has been added.	No effect.

	Change	Effect
1	The constant DFB_GRAPHICS_ENGINE_DESC_NAME_LENGTH with value 64 has been added.	No effect.

	Change	Effect
1	The constant D_String with value Direct::String has been added.	No effect.
