Addendum
An addendum is a change to a bid package issued after it is posted and before bids are due.
It can change the scope, the drawings, the due date or the answers to bidders' questions, and bidders usually have to acknowledge each one.
On a real bid
Agencies post addenda on the same page as the original bid, often as separate files with numbers. A bid that does not acknowledge every addendum can be thrown out as non-responsive.
Addenda matter most late in a bid: a changed specification or a new due date often arrives in the last week.

Where Capveon reads it
Capveon reads every addendum with the rest of the package, so an answer that changed points to the addendum that changed it.
