I think I'll hold off on that 10.13.1 "security update" it keeps bugging me about. Seems to let anyone use my computer...
Edit: After looking a little further, it seems staying on Sierra will always be a 10.12.* version, and High Sierra is 10.13.*?
- Mavericks (10.9.x)
- Yosemite (10.10.x)
- El Capitan (10.11.x)
- Sierra (10.12.x)
- High Sierra (10.13.x)
