Some updates are needed for CompositeData.xml and Transform scripts in the process.
Edit: I just updated the attachment to the last post Working With Transformations to remove a couple of glyphs from Fixed Width Figures, and changed the width from 1500 to 1024 funits, which is a more sensible average width. Users will have to edit the width anyway for their fonts.
Take a look at Leon's thread to see what updates might be needed.
