 Implementing expiration (or another use for these bytes) will be a backwards-incompatible change.
 Routers MUST set this field to all zeros.
+As of release 0.9.12, a non-zero expiration field is again recognized, however we must wait
+several releases to use this field, until the vast majority of the network recognizes it.
