That's exactly right, yeah - the tools libraries and add-ons themselves are version-specific, but to open projects in newer versions, they migrate without you needing to do anything.
WRT new features - there actually have been a quite lot recently. Since the initial v24 release came out we've released 3 updates, each containing a handful of new feature additions, and we also recently built a powerful Preset engine into the tool which allows you to build full catalogs of joinery elements, setup snappable sizing tables, and automatically generate type codes on the fly.
