	Change	Effect
1	Type of 2nd parameter chart_ref_id has been changed from uint16_t (2 bytes) to uint32_t (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.
2	Type of 3rd parameter drawing_id has been changed from uint16_t (2 bytes) to uint32_t (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.

3	Value of member LXW_ERROR_32_STRING_LENGTH_EXCEEDED has been changed from 13 to 18.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
4	Value of member LXW_ERROR_IMAGE_DIMENSIONS has been changed from 20 to 25.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
5	Value of member LXW_ERROR_INVALID_SHEETNAME_CHARACTER has been changed from 11 to 14.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
6	Value of member LXW_ERROR_NULL_PARAMETER_IGNORED has been changed from 8 to 11.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
7	Value of member LXW_ERROR_PARAMETER_VALIDATION has been changed from 9 to 12.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
8	Value of member LXW_ERROR_SHARED_STRING_INDEX_NOT_FOUND has been changed from 17 to 22.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
9	Value of member LXW_ERROR_SHEETNAME_ALREADY_USED has been changed from 12 to 16.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
10	Value of member LXW_ERROR_SHEETNAME_LENGTH_EXCEEDED has been changed from 10 to 13.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
11	Value of member LXW_ERROR_WORKSHEET_INDEX_OUT_OF_RANGE has been changed from 18 to 23.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
12	Value of member LXW_ERROR_ZIP_CLOSE has been changed from 7 to 10.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Size of field options has been changed from 16 bytes to 24 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.

	Change	Effect
1	Type of field vba_codename has been changed from uint8_t (1 byte) to char* (8 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.
