More significantly though is that the geometry has been pulled
from the props and converted into external OBJ files in the
Geometries folder reducing scene file size dramatically.
Also many more Camera & Light presets have been added to all of
the props making all of them easier to use. Some of the props
originally shipped with no presets at all! Finally, all five of
the props have now been made to work by default in Standard Poser
rather than Pro Pack.
I think all of this qualifies this release as a significant
upgrade rather than a simple bundling of old products.
