I released Zupiter on June 1, 2003. The name was a playful distortion of “Jupiter,” meant to suggest classic science fiction. The design was conceived as a display face with semi-serif letterforms; the uppercase was more successful than the lowercase, where characters like the “e” did not meet my intentions.
In 2021, I updated Zupiter to resolve several technical issues. Deprecated characters such as L with dot and E with breve were removed; the ellipsis was narrowed to a more reasonable width; and the OpenType fractions feature was expanded to support extended numerators and denominators, including values like 13/64 or 199/200. I also refined outlines to correct errors in some curves that could cause rendering problems, and I adjusted vertical metrics to improve cross-browser compatibility. These adjustments did not alter scaling in Adobe applications.
Zupiter was always sold commercially; it was not offered free. On November 9, 2022, I placed it into the public domain.
