ufo2glyphs changes custom parameters on Glyphs 3 files

[elitype]

Hi everyone,

I'm using glyphsLib 6.7.1 and I'd like to ask if there's a way to avoid the changes on custom parameters on Glyphs 3 files when I do a roundtrip, it also changes version 3 to version 2 and deletes the variable font export instance, or the panose defined on each instance is placed under the font tab, it takes a long time to remove all those changes, I wonder if is it possible to do a cleaner roundtrip.

Thank you in advance.

Can you try the 'Glyphs3-merge' branch? It supports glyphs 3 file much better.

Thank you Georg, the branch minimizes the changes, still does some in font info:
it duplicates the GASP table and Axis Mappings under the font tab
under the masters tab, it adds Gasp table, openTypeHheaCaretOffset, winAscent, WinDescent; it removes weightClass and widthClass.
under the exports tab it removes the Variable instance
In general it works much better!

That is very good feedback. I'll add those to the test cases.
