chartsheet.h
[+] struct lxw_chartsheet 3

	Change	Effect
1	Field chart 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	Field is_protected 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.
3	Field protection 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.

[+] affected symbols: 34 (8.9%)

worksheet.h
[+] struct lxw_protection 2

	Change	Effect
1	Field no_content 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	The relative position of field no_sheet has been changed from 15 to 16.	Applications will access incorrect memory when attempting to access this field.

[+] struct lxw_chartsheet 1

worksheet.h
[+] struct lxw_protection 2

	Change	Effect
1	Size of this type has been changed from 23 bytes to 24 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field content has been renamed to no_objects.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

[+] affected symbols: 107 (28.1%)

	Change	Effect
1	Size of field protection has been changed from 23 bytes to 24 bytes.	Previous accesses of applications and library functions to this field may be broken.
