Why is my Office 2019 Ribbon exactly like Office 2016's Ribbon?

Hey all,

I recently installed Office 2019 on my work PC, and I've noticed that the ribbon for it looks exactly like it did in Office 2016.  In fact, aside from the version number, there is no change in the UI whatsoever.  This is the standalone installation from my Visual Studio Enterprise account.  Any ideas?

Well, that's because the new ribbon is only available for Office 365 Insiders... for now.
