I'm confused about the different oculus packages

I'm trying to upgrade/downgrade between different versions of Unity Integration (v1.40 was released today).

I've tried downloading manually, and importing it from the asset store. I see a bunch of import progress, but when I check my package manager, I see two things: "Oculus Android" and "Oculus Desktop". I expect to see a package called "Oculus Integration" but it's not there.

My questions:

1. Are Oculus Android and Oculus Desktop synonymous with "Oculus Integration"?
2. No matter what I do, the versions that appear in the Package Manager for Oculus Android and Oculus Desktop are 1.38.2, 1.38.1, and 1.36.0 — wheres the 1.40 I've tried to import over and over?
3. Is there some place else I should be looking for "Oculus Integration"?
4. How can I see what version of "Oculus Integration" my project is running?

When I import Oculus Integration, a big import window appears and a ton of progress bars go by, and a success message. But I don't see any changes reflected in my project, or package manager. What am I missing.

Thanks!
