I wrote a post about it, including some tips for how to get it working on your theme, if your theme hasn’t been updated yet.
Update: Whelp, no. It just got rolled back for some fixing. Stay tuned!
I was also surprised by this release with such an unannounced feature, but with a bit of work, the Eihei, Myoan, Reiro, Basho, Daigo, and Genki themes already support custom fonts. I hope this feature will be further developed as it clearly has great potential. It’s worth noting that the fonts use the fonts.bunny.net database.

Yep. It’ll be back! Just not today.

I’d actually be interested if this would also support adding custom font files. At least in version 5.101.1 it’s not possible - but that might be a reason to why it got removed again. 
Anyway, cool that it’s something the Ghost Team is working on! 
It’s back but as a toggleable beta setting, hidden under /ghost > settings (gear icon) > labs. Docs are here: How to use custom settings in Ghost themes - Developer docs
After you turn the toggle on, you’ll see typography settings show up under settings > design & branding > customize. [If you don’t, maybe reload.]
If your theme has been updated (and you’ve got the updated copy activated), you should see the toggle changing your fonts. If it doesn’t, you may need to update your theme. (You can also try the code injection fix offered in my original post.)
For official themes, you can get the latest version by clicking to install it from the theme install section - that’ll overwrite the old copy and install the new one.
For other themes, contact the theme developer.
Update: More about custom fonts:
