Hello, I noticed that CADET Introduction is only available as early as V4.3.0. ([Getting started — CADET](https://cadet.github.io/v4.3.0/getting_started/index.html)) Any idea how I can find CADET Introduction to older versions such as V4.0.1 Thanks. ---

Hi, we only started hosting the documentation online with v4.3.0. Before, we “only” had a LaTeX / pdf document. But you can always go back in our git history and compile it yourself. Out of curiosity, why are you interested in the older documentation? Best Johannes ---

@j.schmoelder Thanks very for your insight. I was reusing some codes written in Matlab from an older version CADET. I had trouble in converting them to python codes. I thought I could get some clues by comparing the new and old CADET Introduction. The problem was solved yesterday. But thanks for your reply!
