As an AI language model, I don't have any context of 1.0 Courier. However, there are a few possibilities:

1. It might refer to version 1.0 of Courier a typeface designed by Howard Kettler in 1955. It was originally intended to be a monospaced font for IBM typewriters but later became a standard typeface used in the printing industry.
