	Change	Effect
1	Field emulate has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 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 emulate_user has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
