Problem with Autohint

All of a sudden, I get this while exporting TTF. Otf export is perfect.

Exporting web fonts brings the same alert.

Do you get this messenge for instances where you use the custom parameter TTFAutohint Options?

Yes. As always

I got this today, just after the update to 2.5

OK - I opened a font i generated successfully few days ago with the old version of Glyphs, both TTF and OTF.
Now with the new version, can’t generate TTF anymore. I get the same error message.

Erich? Georg? anybody?

The API of TTFautohint has changed a bit. I just fixed it. For now, set the Strong Stem settings like this. Screenshot

Those are the recommended settings anyway. Why do you like different settings?

Thanks Georg! Perfect TTF now.
