Problems with Symbols, High Severity (3)

	Change	Effect
1	3rd middle parameter viewport has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
2	4th middle parameter format has been removed from the calling stack.	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	Type of 3rd parameter fontsize has been changed from GLshort (2 bytes) to GLint (4 bytes).	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Symbols, Medium Severity (12)

	Change	Effect
1	10th parameter nr has been removed from the calling stack.	This parameter will be ignored by the function.
2	11th parameter ng has been removed from the calling stack.	This parameter will be ignored by the function.
3	12th parameter nb has been removed from the calling stack.	This parameter will be ignored by the function.
4	15th parameter filename has been removed from the calling stack.	This parameter will be ignored by the function.
5	Type of 2nd parameter producer has been changed from char const* to char* (became non-const).	This function may change parameter producer, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.
6	Type of 1st parameter title has been changed from char const* to char* (became non-const).	This function may change parameter title, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.
7	Type of return value has been changed from GLint (4 bytes) to void.	Applications will not obtain a return value and execution may change.

	Change	Effect
1	Type of return value has been changed from GLint (4 bytes) to void.	Applications will not obtain a return value and execution may change.

	Change	Effect
1	Type of return value has been changed from GLint (4 bytes) to void.	Applications will not obtain a return value and execution may change.

	Change	Effect
1	Type of 2nd parameter fontname has been changed from char const* to char* (became non-const).	This function may change parameter fontname, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.
2	Type of 1st parameter str has been changed from char const* to char* (became non-const).	This function may change parameter str, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.
3	Type of return value has been changed from GLint (4 bytes) to void.	Applications will not obtain a return value and execution may change.

Problems with Symbols, Low Severity (5)

	Change	Effect
1	4th parameter format has been renamed to options.	Renaming of a parameter may indicate a change in its semantic meaning.
2	5th parameter sort has been renamed to colormode.	Renaming of a parameter may indicate a change in its semantic meaning.
3	6th parameter options has been renamed to colorsize.	Renaming of a parameter may indicate a change in its semantic meaning.
4	8th parameter colorsize has been renamed to buffersize.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	3rd parameter fontsize has been renamed to size.	Renaming of a parameter may indicate a change in its semantic meaning.

Problems with Constants (2)

	Change	Effect
1	The value of constant GL2PS_NO_FEEDBACK has been changed from 4 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_OVERFLOW has been changed from 5 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.
