George:

Sorry I don't remember back to what the 2015 version was like (heck I can scarcely remember last week! LOL).
Are you wanting to have the tempo shown just in the main chord grid window?
Or are you referring to showing it in the Notation / Leadsheet window, and printing it out?

Somewhere along the line BIAB introduced "Layers" where you can insert text right above the chords in the chord grid window.

Let us know more about where you'd like the display. Someone here may be able to help.
Good luck!
