|
Change |
Effect |
| 1 |
Field fMetadata 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 |
Size of field fGraphManager has been changed from 14 bytes to 15 bytes. |
1) Size of the inclusive type has been changed.
2) Previous accesses of applications and library functions to this field may be broken. |
[+] affected symbols: 1 (0.6%)
