Approvals should not leave a paper trail of changes that never happened. Now they don't. When you reopen a Purchase Order that is in an approval process and then discard your changes, Sigma no longer creates a PO revision, and the approval process picks up right where it left off.
The result is a cleaner, more accurate history: your POs reflect the revisions you actually made, not the ones you reconsidered.
This release also adds Comments to PO Adjustments. A new "plus" icon on any Adjustment field lets you attach a note, so the context behind a freight charge, an overage, or any other adjustment travels with it.
