Variable Font Beta?

Hi

I’m currently using Glyphs 2. I’m trying to create a Variable font. When I go to export > variable font it says Beta. Ive read here I think that its Beta because some functionality is missing.

What is the missing functionality

Is it still Beta in Glyphs 3

In Glyphs 2, the possible master positions are limited and some of the extra tables (e.g. STAT) are not fully up to speed. Glyphs 3 is much better and we are about to remove the beta label.

Thank you, I’ll upgrade to Glyphs 3
