Yep, I purchased Dec of '17. According to that page, "It comes with one year of free upgrades and e-mail support." Perhaps they're just on a post-annual update system
FYI, the "new" maintenance release 1.9.8 is for MACOS. AFAIK, 1.9.5 Core Engine is still the most recent for PC.
Still a nice piano - was using it just this weekend.
