APASS 9 to 10 Record Identifier

APASS 9 has a field labeled "recno" which I assume is a unique record identifier.  When I query APASS 10 on this site I do not see that field.  Is it the case that it was not possible to preserve the match of objects between versions so this identifier was dropped?  

thanks for any clarification,
