More libraries have been released recently. It doesn’t help that the Steinberg site is currently split - you start at the old www.steinberg.net but some new products are only on new.steinberg.net (which you cannot visit directly, as it redirects to www.steinberg.net). Some products are on both, some are not. Hopefully Steinberg will get everything on new.steinberg.net soon and retire the old web site.
If you go to the page for Electric Bass, which is one of the recent releases, and click ‘more products’ at the top, you will see Zilhouette Strings, Vibrant, RAST-A, Olympus Choir (two editions - the smaller Elements is included in Dorico 3 Pro and Absolute 4), Hybrid Bundle (which can also be brought as separate products POLY and WAVE), Bouncy Vibrations and Future Bass. Most if not all of these have been announced in the past six months.
