UFO Export version

Glyphs 3 (3112) is exporting UFO version 2 for my current project, despite statement in the handbook that exports are always in version 3. I can’t figure out how to change this. It looks like it might be okay to change the UFOFormat field (which currently says “2”) in the UFO.lib section of fontinfo.plist, but editing Glyphs files makes me nervous. Is there some way to change the UFO export version inside the app?

Editing the .glyphs file is meant to be done. It is a text based format for that reason.
But you can do it with that line in the macro window:

Font.userData["UFOFormat"] = 3

Or even better:


Thank you, Georg!
