	Change	Effect
1	Field reliableWindows 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 usedReliableWindows 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 incomingUnreliableSequenceNumber has been removed from this type.	Applications will access incorrect memory when attempting to access this field.
