EMRFD Errata:

Most  EMRFD errata entries will contain markings with an icon to tell the reader the status.   These are:
for those errata that were fixed in the 3rd printing.
signifying errors that are still in the third printing.  They may just have been too difficult to fix.
This signifies an error that is new in the 3rd printing, or one that we just discovered.
