Hey folks,
I’m still using V1.3 so this question may be redundant.
Is it possible to Change the OS/2 table to V4?
I’m particularly interested in enabling bit 7.
Bit 7 was specified in OS/2 table v. 4. If fonts created with an earlier version of the OS/2 table are updated to the current version of the OS/2 table, then, in order to minimize potential reflow of existing documents which use the fonts, the bit would be set only for fonts for which using the OS/2.usWin* metrics for line height would yield significantly inferior results than using the OS/2.sTypo* values. New fonts, however, are not constrained by backward compatibility situations, and so are free to set this bit always.

I can change the table outside of GlyphsApp. However, I prefer to use as little external editors/hacks as possible.
Thanks,
Marc
