Hi Brian, There don't seem to have been many new plants with Vue 4, but the ones that are for sale aren't included with any version of Vue, and yes, they will work with Vue 4. There are a few free ones there, marked with "free". There evidently also is a zip file of updated plant materials (free for download) which they recommend people get, since the way Vue 4 handles materials is different from the way Vue 3 does.
