Problems with Symbols, High Severity (2)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _Z17minlbfgsiterationR10lbfgsstate to _Z17minlbfgsiterationR13minlbfgsstate. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _Z14minlmiterationR7lmstate to _Z14minlmiterationR10minlmstate. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Field stpmax 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.
2	Type of field optstate has been changed from struct lmstate (980 bytes) to struct minlmstate (1036 bytes).	1) Size of the inclusive type has been 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 (2)

	Change	Effect
1	Size of this type has been changed from 1308 bytes to 1372 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Type of field optrep has been changed from struct lmreport to struct minlmreport.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
