Problems with Symbols, High Severity (2)

	Change	Effect
1	Parameter buffersize of type GLint has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	The pointer level of 2nd parameter size has been increased from 0 to 1.	The library function may try to access unallocated memory by the dereferencing of old parameter value and therefore cause a crash of applications.

Problems with Symbols, Medium Severity (1)

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

Problems with Symbols, Low Severity (15)

	Change	Effect
1	3rd parameter mode has been renamed to sort.	Renaming of a parameter may indicate a change in its semantic meaning.
2	5th parameter feedsize has been renamed to colormode.	Renaming of a parameter may indicate a change in its semantic meaning.
3	7th parameter rgba has been renamed to colormap.	Renaming of a parameter may indicate a change in its semantic meaning.
4	Type of return value has been changed from void to GLvoid (0 bytes).	Replacement of return type may indicate a change in its semantic meaning.
5	Type of 6th parameter colorsize has been changed from int to GLint.	Replacement of parameter data type may indicate a change in its semantic meaning.
6	Type of 4th parameter options has been changed from int to GLint.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of return value has been changed from void to GLvoid (0 bytes).	Replacement of return type may indicate a change in its semantic meaning.
2	Type of 1st parameter mode has been changed from int to GLint.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of return value has been changed from void to GLvoid (0 bytes).	Replacement of return type may indicate a change in its semantic meaning.
2	Type of 1st parameter mode has been changed from int to GLint.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	2nd parameter size has been renamed to fontname.	Renaming of a parameter may indicate a change in its semantic meaning.
2	3rd parameter font has been renamed to size.	Renaming of a parameter may indicate a change in its semantic meaning.
3	Type of return value has been changed from void to GLvoid (0 bytes).	Replacement of return type may indicate a change in its semantic meaning.
4	Type of 3rd parameter font has been changed from int to GLint.	Replacement of parameter data type may indicate a change in its semantic meaning.
5	Type of 2nd parameter size has been changed from int to char*.	Replacement of parameter data type may indicate a change in its semantic meaning.

Problems with Constants (4)

	Change	Effect
1	The value of constant GL2PS_BSP_SORT has been changed from 4 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 GL2PS_DRAW_BACKGROUND has been changed from 8 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 GL2PS_SILENT has been changed from 32 to 4.	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 GL2PS_SIMPLE_LINE_OFFSET has been changed from 16 to 2.	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.
