How safe is Glyphs 2.0?

How safe is Glyphs 2.0 for generating fonts?

Is it the same “engine” as Glyphs 1.0 and will generate same quality, or are there bugs that need to be addressed before retail fonts can be generated with 2.0.

I want to start using 2.0 but have so many crucial deadlines, so I don’t want to find problems along the way.

The export from Glyphs 2 should be even saver as I fixed seveal bugs.
