alt Hacker NewsYou now fully support version 1.0. IIRC, the first version of Mathematica I used back in early 1993 was 2.1 soon followed by 2.2, which was useful for a couple of years. How much extra work is it to reach full compatibility with that version? (I had used MathLink at the time.)
We currently support almost everything up to version 6.0. Here is a detailed comparison with all Mathematica versions: https://woxi.ad-si.com/docs/comparison/mathematica/
However, MathLink is one of the few exceptions as it is deprecated by now.
