Tighter nesting, release after release
The packer's job is to fit your parts into less film, and every metre it saves is material you do not buy. It keeps getting better at it: candidate positions now come from how far a part's material actually reaches in each row rather than from its bounding rectangle, cutouts in large panels can be used as material, and a plotter run is priced in so the packer stops giving a whole sheet away to save a millimetre.
This one is never going to be finished, so it will not be marked as done. There is always a tighter layout, and we will keep looking for it.
