Change to package asd (in archive asddigraphs) for release 1.13: 

ASDParser, now in version 1.07, has been modified to correct an
error that occurred, in rare circumstances, in its handling of 
semantic feature values.  Specifically, in some cases when a 
parse that was two or more levels deep in suspended subphrases
backtracked to an earlier state, a semantic feature could retain
an updated value rather than reverting to its value in the 
earlier state.
