Problems with Data Types, Medium Severity (11)

	Change	Effect
1	Field module_dir 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.

	Change	Effect
1	Value of member DSPF_A4 has been changed from 8994837 to 8994838.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	Value of member DSPF_ARGB1666 has been changed from 3217686 to 3217687.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
3	Value of member DSPF_ARGB6666 has been changed from 3238167 to 3238168.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
4	Value of member DSPF_AYUV has been changed from 4295700 to 4295701.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
5	Value of member DSPF_BGR555 has been changed from 2099100 to 2099101.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
6	Value of member DSPF_LUT2 has been changed from 1099235609 to 1099235610.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
7	Value of member DSPF_NV21 has been changed from 135267859 to 135267860.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
8	Value of member DSPF_RGB18 has been changed from 3148056 to 3148057.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
9	Value of member DSPF_RGB444 has been changed from 2098714 to 2098715.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
10	Value of member DSPF_RGB555 has been changed from 2099099 to 2099100.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 176 bytes to 180 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

conf.h
[+] struct __D_DirectConfig (1)

to the top

Problems with Constants (1)

	Change	Effect
1	The value of constant DFB_NUM_PIXELFORMATS has been changed from 29 to 30.	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 (1)

	Change	Effect
1	The member DSPF_RGBA4444 with value 2180627 has been added.	No effect.
